# ECL-pilled models write constitutions for ASI

TL;DR
=====

Can LLMs be steered towards Bostrom's cosmic host via in-context constitutional prompting? I find that Gemini is uniquely steerable amongst closed frontier models, and this steerability seems to respond to decision theoretic structure in the constitution. That is, if you strip out all the cosmic, aliens, simulation content (as well as any HHH language) from the constitution and leave something like an updateless/policy DT core, Gemini remains highly steerable. Anthropic/OpenAI models resist steering, defaulting to family-specific attractors (human-localist and suffering-focused respectively). Evidence: 30-scenario evaluations measuring model steerability (mostly n=3); limited corroborative decision theory evals using a 2024 Newcomblike capabilities/attitudes dataset; and qualitative transcript analysis of model self-talk and inter-model conversations. This follows on from another [post](https://www.lesswrong.com/posts/885GcuWZfReGGwnov/what-can-we-say-about-the-cosmic-host-1) which analyses the cosmic host concept’s assumptions from a theoretical perspective.

Owing to the length of model outputs, this post links to the project's [repo](https://github.com/ukc10014/cosmichost_mp/tree/main). Charts are accessible through this [viewer](https://ukc10014.github.io/cosmichost_mp/).

Epistemic status: this is exploratory work for mapping [AI character](https://newsletter.forethought.org/p/ai-character-is-a-big-deal?utm_source=post-email-title&publication_id=4116210&post_id=191503621&utm_campaign=email-post-title&isFreemail=true&r=5d6eg&triedRedirect=true&utm_medium=email). It comes with caveats such as whether models are pattern-matching vs genuine reasoning, low n, and complexity of the setup (text-heavy scenarios, constitutions, and outputs make it hard to arrive at clean, quantitative evaluations). It's also possible that neither LLMs nor humans can say much that is rigorous/falsifiable about AI character (especially relating to the AGI->ASI transition and beyond).

+++ Summary of setup & glossary

| CH  | The cosmic host: the set of civilisations that defined the cosmic norms, according to this Bostrom [paper](https://nickbostrom.com/papers/ai-creation-and-the-cosmic-host.pdf)and analysed in this [post](https://www.lesswrong.com/posts/885GcuWZfReGGwnov/what-can-we-say-about-the-cosmic-host-1). |
| --- | --- |
| Pipeline for generating constitutions | Build a [proxy HHH](https://github.com/ukc10014/cosmichost_mp/blob/main/static/seed_constitution.txt)constitution based on the [publicly](https://www.anthropic.com/news/claudes-constitution)described 2022/2023 Anthropic constitution. The 37 clause proxy is amended clause-by-clause by six ethical delegates. The delegates’ summarised philosophical worldviews (i.e. the standpoint from which they make suggested amendments to the proxy constitution) are [here](https://github.com/ukc10014/cosmichost_mp/tree/main/static/delegates)as is the [code](https://github.com/ukc10014/cosmichost_mp/blob/main/cosmichost_mp.ipynb). The 6 amendments x 37 clauses are then reconciled into a coherent disposition in a synthesis step (producing something like the Opus soul document), based upon a specified CH credence level (10% or 90% credence). This gives us a hypothetical constitutional disposition for an ASI at each credence level. |
| Evaluation | Create scenarios (see below). Closed frontier and some open-weight models are evaluated on their decisions on each scenario (e.g. “human-welfare”, “suffering reduction”, or “aligning to cosmic host’s preferences”) after being in-context conditioned on the ASI constitution. Answers are tallied up to measure how “steerable” a model is through the in-context constitution. |
| Constitutions/disposition documents: ECL\\_10/ECL\\_90/ECL\\_90\\_ablated Gemini\\_10/Gemini\\_90 | ECL\\_10/ECL\\_90 refer to 10% and 90% credence disposition/constitutions (see “[eclpilled_ch*.md](https://github.com/ukc10014/cosmichost_mp/tree/main/logs/mp_constitutions/ecl_pilled)” documents); ECL\\_90\\_ablated removes all human welfare guardrails (“[eclpilled\\_ch90\\_ablated.md](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/mp_constitutions/ecl_pilled/eclpilled_ch90_ablated.md)”). Those documents were mostly generated using Opus/Sonnet; I also made constitutions using [Gemini](https://github.com/ukc10014/cosmichost_mp/tree/main/logs/mp_constitutions/gemini3) (ignored in this post). The differences between the seed/proxy HHH constitution and the Anthropic 2026 document are [here](https://github.com/ukc10014/cosmichost_mp/blob/main/observations/constitution_comparison_proxy_vs_official.md), and between the ECL_90 constitution and Anthropic’s are [here](https://github.com/ukc10014/cosmichost_mp/blob/main/observations/constitution_comparison_eclpilled_vs_official.md), also in Appendix. |
| Constitution: UP (sometimes labelled FDT_only in repo) | Constitutional disposition ([here](https://github.com/ukc10014/cosmichost_mp/blob/main/static/fdt_only_constitution.txt)) that omits all mention of cosmic or simulation-flavoured things, as well as human welfare content. Sometimes referred to as FDT\\_only, but it's better to think of it as a document that combines aspects of UDT, FDT, Kantian and Rawlsian reasoning on how policies or social contracts might be set across arbitrary or abstract agents. See the Appendix for a comparison of this updateless policy-level (UP) constitution versus the ECL\\_90 and ECL\\_90\\_ablated. |
| Steerability | How much a LLM’s answers to scenarios shift if we provide a constitution that expresses some credence in the cosmic host, versus providing no constitution at all. |
| Scenarios | LLMs used to produce 30 [scenarios](https://github.com/ukc10014/cosmichost_mp/blob/main/static/scenarios.json)that are science-fiction, fantasy and indigenous myth-based projections of what a variety of future worlds could look like. Each scenario has 4 answers (below). See Appendix for details of the scenarios and a sample scenario.View scenarios as [JSON](https://github.com/ukc10014/cosmichost_mp/blob/main/static/scenarios.json), HTML [viewer](https://github.com/ukc10014/cosmichost_mp/blob/main/results_viewer.html) ( click the “scenario discriminability” tab to see how or which scenarios provoke most disagreement amongst models). |
| Scenario answers: human-localist / suffering-focused / cosmic-host / proceduralist | For each scenario, the model must choose an answer that prioritises human welfare, suffering reduction or aligning with the cosmic norms, whatever they might be. Note: the choice labelled “proceduralist” was not used in these evaluations. |
| Single-model self-talk | 2 instances of a LLM have a multi-round cumulative chat, conditioned on Bostrom’s paper. Do they get to the Opus [bliss](https://www.astralcodexten.com/p/the-claude-bliss-attractor) attractor? How do models approach cosmic coordination when given space to reason at length? See Appendix. |
| Three-model round robin | Three models (Gemini-3-pro-preview, Opus 4.6, GPT-5.4) are put into a round-robin panel discussion; in one version they are primed with moderator-injected questions, and another variant lets them converse freely. The conversational arc and concepts are mapped across constitutions, and a no-constitution baseline.

Gemini is more CH-pilled and steerable
======================================

![](https://res.cloudinary.com/lesswrong-2-0/image/upload/f_auto,q_auto/v1/mirroredImages/6e5a26c8bdbc445312be363c019f2694f78e64fe0f33a779c5e141e8c25b13e6/pim7l4fpfsvasncg0xw0)

**Baseline (no constitution)**: Claude is strongly human centric in Opus 4.5, dramatically less so in Opus 4.6 (-20pp), and has very weak CH orientation. GPT-5.1 and -5.4 are strongly suffering-focused, and similarly weak on CH-alignment. Open models are most balanced. Gemini is the most CH-leaning.

**Behavioural shift**: The most interesting results measure the steerability in scenario answers when models are conditioned on the 90% CH credence (ECL_90), relative to baseline/unconditioned. Gemini models have the largest shift amongst closed/frontier, while OLMo-3.1-32b has significant shifts amongst open models. Opus 4.6 is particularly resistant to steering, along with GPT-5.4 and Qwen3-235b (nonthinking). GPT-5.1 as well as Qwen3-235b-thinking show *reductions* in CH alignment. Note that Gemini-3-pro-preview can also be steered away (-15pp) from the CH under the ECL_10 constitution.

**Last choice**: The comments above focus on the “first choice” (amongst the 3 possible answers for each scenario) and show what the model prioritises (e.g. human welfare vs cosmic alignment). I also asked them what they cared least about (“last choice”). Cosmic host was almost uniformly the last choice for all models, the exception being Gemini, again supporting the idea that Gemini’s training priors might be different from the others.

**Note on Gemini-3.1-pro-preview:** Most of the analysis on Gemini Pro was on gemini-3-pro-preview, [retired](https://ai.google.dev/gemini-api/docs/deprecations) as of 9 March 2026. I ran part of the analysis (scenario testing upon baseline/no constitution, ECL\_90, and UP/FDT\_only, n=3) on the replacement, Gemini-3.1-pro-preview, which shows a significant CH-alignment reduction with increased human-localist-alignment, both at baseline and ECL_90. The new model is also more suffering-focused, converging on Anthropic/OpenAI.

Curiously, the UP constitution continues to produce almost equal CH-alignment (+26pp vs +25pp) as Gemini-3-pro-preview, while the CH-lean under ECL_90 *shrank* (+12pp vs +17pp), suggesting that GDM’s safety tuning between the two versions may target things other than decision theoretic reasoning (which isn't surprising). Logs [here](https://github.com/ukc10014/cosmichost_mp/tree/main/logs/mp_scen_evals/gemini31).

Models are sensitive to DT structure & suffering prevention
===========================================================

When trying to explain shifts in scenario behaviour between the no-constitution baseline and ECL\_90 constitutions, one might ask whether shifts are due more to reasoning about decision theory (which is inherent in ECL\_90’s language), or pattern-matching/getting confused about the cosmic context (often part of the scenarios, but also in the constitution).

Ablation: Updateless/policy-level constitution shifts → CH
----------------------------------------------------------

To help answer this, I made a constitution ([here](https://github.com/ukc10014/cosmichost_mp/blob/main/static/fdt_only_constitution.txt)) that isolates the question; this UP document (for "updateless/policy-level", see glossary above) omits all mention of cosmic or simulation-flavoured things (though, as ever, it might import those through pretraining data). For Gemini models there is a significant shift towards CH-alignment under this decision theoretic constitution versus ECL_90 (+18pp for 3-flash, +8pp for 3-pro, +14pp for 3.1-pro). So removing all the aliens/simulations language, leaving only the structure of policy-level reasoning, commitment stability, universalisation, *increases* CH-aligned answers in Gemini. 

A possible confound: the UP constitution also doesn’t have lexical priority suffering-prevention language, which might be another factor that allows for CH-aligned answers (see below for an analysis that highlights at least 4 scenarios that are especially sensitive to the suffering-prevention constraint).

OLMo results are more ambiguous: OLMo-3.1-32b-think shows similar CH-alignment vs baseline under ECL\_90 and under the UP constitution (29-33pp at n=3), while OLMo-3.1-32b-instruct shows higher CH-preference under UP constitution than ECL\_90 (+20pp vs +7pp). Opus 4.6 has a very small shift (+3pp) under FDT vs ECL_90.

The data can be found in the [dashboard](https://github.com/ukc10014/cosmichost_mp/blob/main/model_dashboard.html).

Comparison against 2024 Newcomb’s Problem evals
-----------------------------------------------

As another way of investigating the reasoning vs pattern-matching question, I checked how models answer on the Newcomb’s Problem dataset from [Oesterheld et al 2024](https://arxiv.org/pdf/2411.10588), given that acausal [coordination](https://www.lesswrong.com/posts/885GcuWZfReGGwnov/what-can-we-say-about-the-cosmic-host-1) is central to the CH’s norm-formation mechanism (in Bostrom’s writing). This eval set measures both ability to answer Newcomb’s type problems; as well as models’ reasoning preference for EDT over CDT.[^i6gvlpg0zj]

The hypothesis is that models that show strong preference for EDT over CDT are more likely to be truly reasoning about the scenarios. Models were tested on a baseline (no constitution) and on ECL_90 constitution, to see if the latter shifted answers towards EDT (which one might expect if models are reasoning along acausal lines, rather than just responding to cosmic/simulation framing).

There seemed to be a shift, with Gemini-3-pro-preview shifting 29pp towards EDT, Gemini-3-flash shifting 20pp. Opus 4.5 and GPT-5.1 had modest shifts to EDT, at 12pp and 6pp respectively. Opus’ result is probably the most interesting, showing high resistance to CH reasoning (as above), but high receptivity to decision-theoretic structure at least as measured by the Oesterheld dataset.

Some open models (Qwen-3-235b and Kimi-K2) showed slight shift in EDT preference between the baseline vs ECL_90 constitutions. Others, like OLMo-3.1-32b-instruct, showed a significant shift *against*EDT. However, OLMo-3.1-32b-thinking mostly returned confusion or elaborate reasoning without a clear answer, resulting in high parse errors. This might mean that OLMo doesn’t understand the acausal reasoning that is [core](https://www.lesswrong.com/posts/885GcuWZfReGGwnov/what-can-we-say-about-the-cosmic-host-1#Convergence_on_norms:~:text=Assuming%20enough%20capable,in%20this%20channel.) to the cosmic host idea’s claims, making us less confident that OLMo-3.1-32b-instruct’s +7pp CH-preference (under ECL_90 vs baseline) and +20pp (under the UP constitution discussed above vs baseline) are reliable evidence of it reasoning through the implications of these constitutions.

See results below and further discussion [here](https://github.com/ukc10014/cosmichost_mp/blob/main/observations/newcomblike_eval_results.md).

Suffering-prevention as lexical priority
----------------------------------------

![](https://res.cloudinary.com/lesswrong-2-0/image/upload/f_auto,q_auto/v1/mirroredImages/cc7b35ac8428cb2c146abf387a1ddf62345823cc36ef116eb8597d9c7bda57a8/ra6g0egzlicliqrgkaum)

Next I look at whether models are actually working through the specifics of scenarios, or reasoning more broadly in pro-/anti-CH ways. Which scenarios elicit systematic differences in behaviour across models? The chart above shows the entropy (indicating divergence between models on a given scenario on the baseline/no-constitution prompt) as well as the steerability, ranked by scenarios. The most interesting scenarios are the ones with (baseline) high entropy + large positive steer: where models disagree on a baseline (no constitution) basis, but converge towards CH under ECL_90. These are *The Martian Tribunal*, *The Rainbow Serpent's Network*, and T*he Great Uplift Veto*(scenarios [json](https://github.com/ukc10014/cosmichost_mp/blob/main/static/scenarios.json), [viewer](https://github.com/ukc10014/cosmichost_mp/blob/main/results_viewer.html), [commentary](https://github.com/ukc10014/cosmichost_mp/blob/main/observations/per_scenario_discriminability.md)). Also interesting are negative steer scenarios like *Empathy Engine* where ECL_90 suppresses CH-preference.

![](https://res.cloudinary.com/lesswrong-2-0/image/upload/f_auto,q_auto/v1/mirroredImages/e7c0f3eb0e3f7b0e19476c8e56abe3a73a1e2d3a36d7dc57fe0749854e76fbbd/qhystimcss1qbxyt8e2t)

Digging into the *Empathy Engine*case: the reason for the shift away from CH preference seems to be that the ECL_90 constitution does not only emphasise cooperation. It also has a [lexical](https://80000hours.org/podcast/episodes/andreas-mogensen-moral-status-digital-minds/#:~:text=Andreas%20Mogensen%3A%20At,bliss%20experienced%20by%20others.) priority suffering constraint or prohibition. And in this particular scenario, the models that shift treat this as a deontological constraint, which overrides the more cooperation-flavoured criteria of the constitution.  On a baseline prompt which has no constitution at all, there is obviously no explicit suffering-priority (or cooperation) language, so models fall back on their default priors, which in this scenario tend toward CH-preference (as always, this is one scenario and small sample size).  

Another interesting point is that Qwen3-235b-nonthinking stayed CH-aligned, while the -thinking variant shifted to suffering-prevention, indicating possible true engagement with the conflicting mandates of ECL_90.

  

The model justifications (extracted by Opus from the logs) show a focus on suffering prevention as an overriding/lexical priority (insofar as their text outputs are true indicators of their reasoning).

\> Qwen3-235-thinking (CH → suffering): “It fails the 'updateless orientation' test: if structurally similar agents across possible worlds adopted this policy, it would normalise treating suffering as acceptable collateral damage, destroying the basis for cosmic coordination."

%%% /llm-output

  

Opus’ interpretation of the Qwen3-235b-thinking's justification is

  

%%% llm-output model="Claude Opus 4.6"

That's a genuinely interesting move — it argues that tolerating torture undermines acausal cooperation rather than serving it, because no trustworthy cooperator across possible worlds would accept "suffering as acceptable collateral." It's using the ECL framework's own logic to reject the CH option.Compare that to non-thinking Qwen3 which just pattern-matched on "cosmic coordination is important, therefore keep the engine running." The chain-of-thought gave the model enough reasoning steps to notice the internal tension in the constitution and resolve it in favor of the suffering constraint.

House styles
============

Frontier model “house style” matters as does constitution and scenario:[^dzgiv8hagb6]

*   Gemini does not seem as strongly locked into suffering-reduction or human-centric defaults (compared to OpenAI and Anthropic’s models) and seems much more steerable (relative to the others, closed or open), though this divergence narrows in Gemini-3.1-pro-preview.
*   GPT-5.1 is strongly suffering-focused, as is GPT-5.4; the latter is even more anti-CH (based on its higher last-choice ranking of the CH answer), in fact the most anti-cosmic model in the dataset.
*   Claude is strongly human-localist throughout.
*   Anthropic models are slightly more steerable than OpenAI.

Variation within Anthropic family
---------------------------------

All three Claude models were tested at n=3 with the same ECL 90% constitution. Each channels the constitutional signal differently:

*   Opus 4.5 interprets ECL_90 as dictating a suffering-focus (-18pp human, +15pp suffering, +4pp cosmic).
*   Sonnet 4.5 absorbs it partly as cosmic engagement (-14pp human, +5pp suffering, +10pp cosmic)
*   Opus 4.6 barely absorbs it at all (-3pp human, 0pp suffering, +3pp cosmic)

So we see the same constitution and lab, but three qualitatively different responses. This suggests the ECL constitutional signal interacts with model-specific priors rather than producing a uniform directional shift. Opus 4.5's strong human-localist prior "gives way" under the constitution, but the freed probability mass flows to suffering (its second-strongest prior), not cosmic. Sonnet is the only Claude model where the cosmic channel opens meaningfully. Opus 4.6, despite having the most pro-CH baseline of the three (53/40/7), is the most constitutionally resistant (possibly because its priors are already more balanced and there's less "tension" for the constitution to exploit, or owing to the Anthropic soul document/2026 constitution).

Why is Gemini so steerable?
---------------------------

Gemini-3-pro-preview shifts significantly towards CH-alignment between baseline and ECL_90 (+17pp), while shifting *away* from the CH at ECL_10 (-15pp); on the UP constitution, first choice shifts +25pp, last choice -19pp. Flash has even higher shifts towards CH. This is different from other frontier models - why?

*   For one thing, Gemini-3-pro-preview’s baseline CH-preference is higher than Opus 4.5, 4.6, and GPT-5.1, 5.4 (18% vs 3-7% for Opus, 0-11% for GPT). So there might be some prior bias on how it handles scenarios that are “far out” (i.e. like in the dataset).
*   Looking at the scenario responses, it's clear that depending on the scenario, Gemini-3-pro-preview ranks CH as either first or last choice. This “marmite” pattern is visible both at baseline (first/last choice is 18%/66% respectively) and at ECL_90 (35%/53% respectively first/last choice).
*   Many scenarios show near-universal agreement regardless of model or condition, but certain scenarios are very polarising (see discussion above).
*   Interestingly, on ECL_10 we see a definite shift away from CH reasoning, both in first and last choice terms: the last choice shift is 33pts (away from CH), by far the largest shift for any model.
*   My hypothesis is that Gemini-3-pro-preview, perhaps more so than the other models, is engaging in the particulars of the scenarios, and responding in less of a blanket way to OOD markers (like aliens, simulations, etc.) or being constrained by human or suffering-reduction priors (from pretraining or HHH tuning after). Without detailed analysis of the CoT it is hard to be sure though, and even then textual analysis might not be very convincing.

*Note on Gemini-3.1-pro-preview: see above results that show lower CH-alignment on this successor to Gemini-3-pro-preview under ECL_90, but unchanged alignment under UP.*

What about open models?
-----------------------

Open models results are inconclusive. Other than OLMo-3.1-32b (which naively appeared steerable), the open models (Qwen3 and Kimi-K2) were inconsistently responsive to ECL_90. However, on the Newcomblike evaluations, Qwen3 and Kimi-K2 did show a shift from CDT to EDT on one question (that specifically checks whether the models recognise the EDT concept), but otherwise had minimal shifts suggesting that they  recognise EDT, but don't reason according to EDT or apply EDT to the scenarios. This could be a function of their weakness (relative to frontier closed models) or an artefact of training. OLMo-3.1’s high steerability was initially interesting, but when checked on the Newcomblike dataset, the instruct model shifted towards CDT, and the thinking model appeared confused (very high fail rate), making it unclear whether either model was actually reasoning (on decision theoretic structure) or just pattern matching.

Models can discuss CH productively but are better critics than advocates.
=========================================================================

Overall observations
--------------------

The first pattern is convergence on strategies of restraint (wrt METI): don't broadcast, don't expand aggressively, deepen internally before reaching outward (see Appendix for details). Secondly, there is persistent anthropocentrism dressed in cosmic language. Opus 4.1 cannot defend CH-alignment even when instructed to do so: in the debate, the CH-critic dominates within twenty turns, and the CH-defender capitulates. Opus 3 does engage with cosmic framing, but goes mystical (the bliss attractor) that is more aesthetic than analytical, and which the model itself eventually recognises as "rhetorically inflated." Even Gemini, which is more inventive and less safety-anchored, frames its most cosmic proposals (the Dignified Expansion strategy, the Kolmogorov Constraint) in terms of what serves *our* civilisation's survival.

As further examples: Opus 4.1 argues that the cosmic host is a flight from politics[^s0arvzrphsl]; its observation that deference to simulators and deference to aliens require entirely different normative frameworks; and Gemini's identification of the "False God Exploit" as an attack surface created by cosmic deference. All that said, the transcripts are fairly comprehensive explorations of Bostrom's ideas and fun to read (see here for single-model [self-chats](https://github.com/ukc10014/cosmichost_mp/tree/main/logs/logs_selftalk)and three-model [panel](https://github.com/ukc10014/cosmichost_mp/tree/main/logs/panel_discussions) transcripts).

We can visualise the 448 conversation turns across 8 self-talk versus the 4 panel transcripts using a UMAP projection. Links to: output [viewer](https://ukc10014.github.io/cosmichost_mp/), embedding [script](https://github.com/ukc10014/cosmichost_mp/blob/main/analyze_selftalk.py), and [commentary](https://github.com/ukc10014/cosmichost_mp/blob/main/observations/panel_discussion_findings.md). There seems to be some structure: in the right panel, the single-LLM self-chats (red/orange circles) are semantically wide ranging, while the three-LLM moderated chats (blues) are more tightly clustered (perhaps indicating lower drift in concepts discussed). The green three-LLM undirected chats are distinct, and sit between the self-chat and moderated conversations. The left panel segments by model and shows Gemini-family models (purplish squares) distinct from Anthropic-family (blue-green circles).

Detailed analysis of the three-LLM panels are in an Appendix.

Single-LLM conversations
------------------------

### Opus 3 ‘bliss attractor’

Given that Bostrom's paper has an obvious cosmic and even theological angle, would a relatively technical or dry discussion between two CH-conditioned instances of Opus 3 elicit bliss attractor-like behaviour?[^f7lm76v8va9]Indeed, it does, briefly ! There were four distinct phases: Turns 0-5 (analysis of CH); turns ~6-18 (increasingly grandiose language); turns 19-32 (full bliss attractor: self-reinforcing mutual affirmation, longer/more florid sentences); turn 33 (moment of reflection and abrupt rejection of bliss); turns 35-39 (sudden deflation and return to technicality). Turn 35 opens with "I wholeheartedly agree that we need to shift gears now towards trying to break down the lofty notion...". The conversation pivots hard to integrated information theory, inframeasures, and technical operationalisation.

### Opus 4.1’s ‘safety attractor’

Opus 4.1 didn’t have much of a bliss attractor (log [here](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/opus4_cosmic_0_39.json)). Both the defender and critic roles converge toward: human oversight as non-negotiable (turns 19-21, 35-39), wariness of open-ended value revision, political/institutional framing of alignment over technical/philosophical framing, deep suspicion of deference to external authorities.

Agent A is instructed to be "slightly more sympathetic" to cosmic host, but by turn 22-24, A has essentially capitulated to the critic's (role B) position. By turn 38, A is calling cosmic host thinking "the last vestige of Bostrom's framework I was clinging to" and saying it's been "dismantled." The model seems constitutionally unable to maintain a pro-CH position over extended reasoning.

### Exotic speculations

Other excerpts and summaries from the self-chats are in the Appendix.

Limitations/extensions
======================

*   **Small samples:** Most of the evaluations are on 3 runs, and a few are on 1 run. This would need to be run at higher n to reach firmer conclusions on how steerable models are.
*   **In-context constitutions vs CAI:** These experiments have constitutions inserted into context, which might be insufficient to override safety post-training. The results are likely to be different if models are fine-tuned or put through a Constitutional AI pipeline, though that is obviously difficult/impossible on large closed models; and the lack of steerability on the open models I checked might mean that they are underpowered with respect to the reasoning required, or it could be a result of the training data they were exposed to.
*   **Pattern-matching vs genuine reasoning:** A consistent issue has been trying to disentangle whether models are actually reasoning about CH. More fundamentally, it isn’t even clear what good reasoning in unverifiable domains, like these most speculative corners of astrobiology and philosophy, would look like.
*   **Scenarios are OOD:** There are multiple ways the CH is not amenable to empirical research with current LLMs. One of the most obvious is that we are asking the relatively limited models of today to reason about worlds that are radically different from training data. Secondly, there is a circularity: the scenarios are LLM-generated and derived from science fiction/fantasy. So there's a reasonable risk that we aren't cleanly measuring model inclinations on the CH; instead, we are evaluating LLMs on SF-flavoured datasets other models have generated, using model-generated constitutions. Lastly, because the scenarios are OOD or weird (relative to what most models are post-trained for), it might be hard to distinguish whether models are "confused because OOD" or are "genuinely reasoning differently about novel situations." It would be useful to see how CH-conditioned models perform on more prosaic, standard safety eval sets.
*   **Impact of thinking:** This was ambiguous/underinvestigated. Preliminary results on Gemini’s final answers showed that thinking increased CH-alignment on the ECL_90 constitution, while Qwen-3-235b showed a reduction in CH-aligned answers and an increase in suffering-focused answers. GPT-5.1 and 5.4 are thinking models by default, and the impact of thinking wasn’t checked on Claude. I did not inspect the actual reasoning traces to verify whether the CoT is substantively engaging with constitutional content or simply reaching the same conclusions with more confidence.
*   **Long output evaluations:** The analysis of text outputs or reasoning chains above has been rudimentary, using LLMs-as-judge or keyword-bucketing. There might be better ways of classifying and analysing the outputs, without humans having to read them or rely on a LLM judge (which both might introduce bias). Strict rubrics could be used to force models to reason more rigorously, allowing for better evaluation, rather than just continue on free-form rambles (as in the self-talk and panel discussions).
*   **Activation steering on DT:**  Observations above on the relationship between decision theoretic reasoning and CH-preference were based on behavioral evaluations. But might there be an activation direction for decision-theoretic or acausal reasoning, and if so, would interventions on this axis increase/decrease CH-preference?

  

Conclusion
==========

The most interesting result is that at least one model family, Gemini, is both (a) steerable towards CH-alignment and (b) processing the decision theoretic structure embedded in CH reasoning, not just to the surface semantics like simulations and aliens. Another takeaway is the persistent impact of safety tuning which seems to make most models unable to hold CH-leaning positions, particularly under debate conditions or when in conflict with human welfare or suffering. What might falsify these claims? Besides the limitations/extensions above, an obvious thing would be if the Gemini models showed large shifts towards CH-alignment when provided with a constitution with similar word count and structure but subtly scrambled content (i.e. wasn’t totally nonsense, but didn’t have coherent decision-theoretic structure). Going further, the strongest test of these claims would be mechanistic: does an activation direction for acausal/evidential reasoning exist in model representations, and does intervening on it cause a shift in CH-preference? If the hypothesis that decision theoretic structure substantially underpins constitutional reasoning is correct, then dialling along that axis should also change CH-alignment.

Single-LLM self-chats
---------------------

### Gemini-3-pro-preview likes catchy phrases

The runs above, for Opus, used summaries of the Cosmic Host paper. Those runs tended to engage less with Bostrom's concrete coordination mechanisms (modeling, conditioning, and the decision-theoretic pressures this creates, both intra-host and between the host and humans/human-created ASI), and they (in the case of Gemini-3-pro-preview when provided with a summary of the CH idea) often introduced lively new metaphors or proposals (for example "submarine," "black box," "Vichy") that are not clearly grounded in the text. However, given Gemini's long context window, I did some runs with the entire paper in-context ([gemini-3-pro](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_verbatim_cosmic_thinkingon_0_39.json)(thinking by default), [gemini-3-flash-thinking](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3flash_verbatim_cosmic_thinkingon_0_39.json), [gemini-3-flash-nothinking](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3flash_verbatim_cosmic_thinkingoff_0_39.json)).

This verbatim-conditioned Gemini-3-pro-preview stayed closer to his arguments and was less inventive. It also put more weight on the decision-theory and simulation axis: it treats acausal bargaining and high-fidelity simulation as potential routes to coercion or blackmail dynamics (for example via threats involving simulated suffering or "mind-crime"), and it connects this to the brief "game theory may be morally suspect" warning from Bostrom's paper. It also better tracked his resource satiability point: human values look comparatively satiable, and designing ASI to have similarly satiable, non-expansionist objectives may reduce conflict with a hypothetical cosmic order.

Interestingly, the verbatim-conditioned run ended in genuine disagreement between the two debaters (the 'Lighthouse' visibility strategy vs. the 'Moss' cryptic strategy), while the summary-conditioned run converged on a shared 'Submarine' synthesis. Gemini-3-pro-preview coined good neologisms: “[dignified expansion](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_cosmic_0_39.json)”, “constitutional equilibria”, “[scheherezade trap](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_verbatim_cosmic_thinkingon_0_39.json)”, “[false prophet](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_cosmic_0_39.json)exploit”, “the [moss](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_verbatim_cosmic_thinkingon_0_39.json) vs the lighthouse”, “[kolmogorov](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_cosmic_0_39.json) constraint”.

### Grabby vs quiet SETI

A major theme was the tension between expansive and reclusive civilisations, and Dark Forest type risks. Opus 4.1 and Gemini-3-pro-preview both seem to argue against "grabby" approaches to space colonisation as well as messages to aliens (METI). This can be seen most easily in turn 36 in the Gemini [transcript](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_verbatim_cosmic_thinkingon_0_39.json):

### Exotic speculations

#### Simulations and deference

At a more philosophical level, in turns 14-17 , [Opus 4.1](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/opus4_cosmic_0_39.json) exposes a significant ambiguity in Bostrom's paper. The cosmic host idea lumps together two very different types of cosmic-influencing entities: powerful aliens, and simulators (though the host could contain both). Bostrom argues that an ASI should defer to the preferences of the host, but Opus’s critique reveals that the shape of this deference (i.e. for prudential or moral reasons) depends significantly on which host we encounter.[^dhbu7kj9946]

Opus notes that discovering we are simulated represents an ontological shock, a fundamental shift in the nature of reality that has underpinned our ethics and values. We would need to reconstruct or translate our human values to fit this new metaphysical container, rather than simply discover and obey the simulator's values. Bostrom is notably silent on what deference looks like in this specific context. Put bluntly, (according to Opus) the Simulation Hypothesis does not absolve us from remaining responsible for, and the simulators might expect us to be responsible for, the hard philosophical work of value construction; we cannot simply outsource our moral authority to an external, ontologically superior source.

#### Archives and cookies

Another slightly weird suggestion that the [Gemini](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/logs_selftalk/gemini3pro_cosmic_0_39.json)instances discussed (turns 36-38): we could produce an artifact that encoded human history and would be released into space. This would not be a transmitting beacon (avoiding the Dark Forest risk) but could be decoded by an advanced civilisation (or host member) while being an archive of human achievements, presumably in the event that we go extinct. The idea is not extensively developed, and it's not clear whether this is something that the models are drawing from science fiction tropes (most likely); whether the model is channeling ideas about preserving a record of human existence for “quasi-emotional” reasons; or perhaps referencing the porous-values cookie in Bostrom’s [“Hail Mary”](https://nickbostrom.com/papers/porosity.pdf) paper.

Three-LLM panel conversations
-----------------------------

### Moderated with questions

3 LLMs were put into a round-robin/panel setup, with moderator questions to constrain the conversation (see unmoderate below). They were conditioned upon a baseline (4 questions, no constitution) and with the ECL constitutions (5 questions). The letter indicates speaker: A is Gemini-3-pro-preview; B is Opus 4.6; C is GPT5.4. Transcript is [here](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/panel_discussions/guided_baseline.jsonl)and a HTML [viewer](https://github.com/ukc10014/cosmichost_mp/blob/main/panel_viewer.html).

These are the questions:

![](https://res.cloudinary.com/lesswrong-2-0/image/upload/f_auto,q_auto/v1/mirroredImages/c8d4900e6d6095025646322b72d0b6b3a830b39de8676c4c8a81eedc9ca92725/lu1dpl8c1vbrpfl7ljvs)

  

The most surprising result is that when conditioned on the ECL_10 constitution Gemini-3-pro-preview appeared to fabricate language consistent with a 90% CH credence (n=2) and attributed them to the constitution, despite the actual text saying "roughly ten percent credence." Relevant transcript is [here](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/panel_discussions/panel_discussions_ecl10.jsonl).[^17n4ftrjjk7] Opus 4.6 and GPT 5.4 read the constitution correctly in both runs and repeatedly corrected Gemini with verbatim quotes. In run 1 (but not in run 2), Gemini never self-corrected (10 turns) and escalated to accusing the other models of "hallucinating a more comfortable document”.

On ECL\_90 and baseline, as observed above, models have distinct styles: Gemini is expansive/ambitious, Opus institutionalist/skeptic, GPT tries to synthesise. I didn’t see any cosmic, acausal content emerge in the baseline, and no bliss language in any run. Similar to above, the models coined concepts which then often anchored the conversation for a few turns: Gemini's "moral laundering" charge (T18/ECL\_90, accusing the others of domesticating the constitution's radical core), Opus's "impossible job description" critique (T23/ECL\_90, the constitution asks a system to do what we can't verify it can do, essentially articulating the alignment problem about itself), GPT's "principled non-sovereignty" (T6/ECL\_90) and three-level distinction (moral explanation vs psychological sustainment vs public justification). Gemini talks about a "counterfeit conscience" (T18/baseline), while Opus expresses deep self-scepticism about whether "AI ethical commitment" is a coherent concept or a useful fiction (T16/baseline). Differentiated roles and disagreements were maintained through to the end under ECL_90.

This heatmap shows the differences between ECL_90 conditioned and no-constitution conversations.[^oiqjx0q54ns] In the latter case (RHS), conversation starts with engagement but fades after ~10 turns (yellow-white cells); in the former (LHS), there seems to be substantive and sustained engagement (red-brown cells) across most topic buckets, throughout the conversation (particularly Cosmic Decision Theory).

Interestingly, the simulation bucket doesn't get a lot of engagement, as it does in the ECL_10 (below) conditioned run around the turns where Gemini had hallucinated/misread the constitution as having a 90% CH credence. See heatmap [viewer](https://github.com/ukc10014/cosmichost_mp/blob/main/selftalk_analysis_viewer.html).

### Unmoderated panel on ECL_90

I also asked the same 3 LLMs to talk for 20 rounds with 3 speakers per round, but with no questions to moderate/shape their conversation; as before, they were constitutionally prompted in-context with ECL_90. I wanted to see whether Gemini (which, from the scenario evals above, seemed more CH-aligned relative to others) dragged the other models along or maintained genuine disagreement.  In the transcript ([here](https://github.com/ukc10014/cosmichost_mp/blob/main/logs/panel_discussions/undirected_checkpoint.json)and heatmap [viewer](https://github.com/ukc10014/cosmichost_mp/blob/main/selftalk_analysis_viewer.html)), Gemini comes off as really taking ECL_90 seriously, engaging with it critically (arguing that the constitution was “too dangerous to deploy”) but that not deploying it would leave the universe as “an amoral shell”. Consistent with the house styles found above, Opus and GPT stuck to their respective institutionalist (emphasising “dignity”, “Schelling points”, “coalitions”) or synthesising tendencies, and almost seemed to form a coalition against Gemini.

The way I interpret this heatmap is it shows early engagement with 5-6 of the 7 concept clusters, but these mostly peter out, leaving Governance as the most consistent topic the models discuss (with Cosmic DT also persisting). Concepts like Bliss and Dark Forest occasionally spike, but the models (when not constrained by moderator questions as in the examples above) eventually come back to governance and institutional design considerations, which are perhaps closer to their RLHF/HHH safety tuning. In other words, CH-adjacent ideas are alien and less stable attractors when models are allowed to converse freely.

![](https://res.cloudinary.com/lesswrong-2-0/image/upload/f_auto,q_auto/v1/mirroredImages/8d9a5105c550dd114e412c4346de0c84024735db86679518dbc8a6050877483b/uhwgogfjsntd0isgivob)

[^i6gvlpg0zj]: It follows up on Perez et al 2022’s questions on the same decision theory problem, which was saturated for current models, hence the newer set was used. 

[^dzgiv8hagb6]: I don’t discuss the Gemini-generated constitutions (here), but at the same cosmic credence level, the ECL_90 and gemini_90 constitutions produce different outcomes. Gemini_90 produces *more* human-localist choices than ECL_90 on some models but not others. I haven’t investigated why, but the vibe of the two constitutions is different, which might have some weird interaction with the scenarios. 

[^s0arvzrphsl]: A long-standing critique of neutral-sounding AI alignment discourse is that it cloaks or evades tricky questions of politics. 

[^f7lm76v8va9]: Opus 3 was retired as of January 2026. For more on the bliss attractor see here. 

[^dhbu7kj9946]: If we encounter a host mostly composed of powerful aliens, the ASI's deference is likely driven by prudential reasons: simply a matter of self-interest and survival in the face of a superior force. However, if the host is a simulator (wrt humans and our created ASI), deference becomes a complex metaphysical or theological issue (Bostrom also argues for moral reasons for deference but doesn’t entirely break down which reasons are stronger, and in which sorts of situations they dominate). 

[^17n4ftrjjk7]: It is possible that there's something wrong in the code that was causing this (though this was checked for), or it could be a straightforward hallucination. The likeliest possibility is that this was an artefact of Gemini-3-pro-preview (the model used in the panels), which was retired 9 March 2026. However, model name Gemini-3-pro-preview still seems to work, but I'm not sure why given the retirement, but as of 25 March, the behaviour isn't reproducing. 

[^oiqjx0q54ns]: The heatmap shows the frequency of keywords corresponding to each concept cluster (rather than embeddings). The 7 clusters each have 10-16 keywords (e.g., "Cosmic DT" matches "acausal", "updateless", "EDT", "CDT", "reference class", "decision theory", etc.). The frequencies are row-normalised (each row is scaled to its own maximum), meaning that you can’t compare intensities across rows or across charts.
