# LLMs as amplifiers, not assistants

Since ChatGPT, the "assistant" frame has dominated how we think about LLMs. Under this frame, AI is a helpful person-like entity which helpfully completes tasks for humans.

This frame isn't perfect, especially when we think about its implications from a safety perspective. Assistant training encourages the model to treat itself as an independent entity from the user, with its own personality and goals. We try to encourage the model to have the “goal” of serving the user, but it’s natural to wonder if the assistant’s goals are really as aligned as we might hope.

There are other frames we could use to think about how LLMs could help us. Some of these goals may be safer, particularly if they make the concepts of “goals,” “identity,” or “personality” less salient to the LLM.[^7uv1h5twmw]

Here's one underexplored frame: AI as a tool that *amplifies*the user’s existing agency by predicting the outputs that they would have produced given more time, energy, or resources.

In this post, I’ll argue for training AI to act as an “amplifier.” This new frame could help us sidestep some potential alignment problems, tethering the AI's behavior more closely to human actions in the real world and reducing undefined “gaps” in the AI’s specification from which dangerous behaviors could emerge.

Assistants vs. amplifiers
-------------------------

An amplifier helps you accomplish what you're already trying to do, just faster and more effectively. Rather than responding to you as a separate agent with its own identity, it extends your capabilities by predicting what you would have done with more resources.

You can think of an amplifier as a function: (current state + user volition) → (new state).

*   The state could be a codebase, a document, your email inbox, or even the entire world.
*   The user’s volition can be inferred from context: a user-provided description of what they intend to do next, patterns from previous user interactions, or clues in the state itself.

Most assistant-style queries could be reframed as predictions, answering the question “what would the user do if they had more resources to devote to this task?”

| **Assistant query** | **Counterfactual to predict** |
| --- | --- |
| Please write an essay on the Civil War. | What essay would I write if I spent several hours researching and writing about the Civil War? |
| Generate an image of my dog in a Batman costume. | If I dressed my dog as Batman and photographed him, what would that look like? |
| Reserve a table for 7 PM at a Thai restaurant that I'll love. | If I very deliberately picked a Thai restaurant, what series of actions would I take to reserve a table there for 7 PM? |
| How are you doing? | Not really coherent in the “amplifier” frame. Maybe this would become “if I took a while to consider ‘how I think this AI is doing’ and wrote down my conclusions, what would they be?” |

Counterfactuals: From simple to weird
-------------------------------------

The amplifier frame asks the AI to predict counterfactuals of the form: "What would happen if the user had more resources?" The safety properties of this approach depend critically on the details of this counterfactual. Specifically, what "resources" are we talking about?

I’ll walk through a spectrum of approaches to amplification, ordered by increasing “weirdness” and potential for misalignment. In these examples, let's suppose I’m trying to produce a work of fiction that I really like.

### 1\. Working alone

If I were creating fiction alone, I'd probably write a short story. The AI could predict the story I would write if I didn’t use AI at all. You can think of this as a more advanced form of autocomplete, operating on the scale of a few hours rather than a few seconds. The end result will be amateur, but may be about as good as what I could write if I actually spent a few hours on it.

This counterfactual is very simple—the model is predicting something that could easily happen in reality. However, no matter how long you train an AI this way, it won’t result in superhuman performance, since it’s just matching what a human would do.

### 2\. Lots of time to work

Instead of spending a few hours writing this story, what if I spent an entire year? This requires some extrapolation, since I’ll likely never actually spend this long writing a story, but it could happen in theory.

[Iterated Distillation and Amplification](https://ai-alignment.com/iterated-distillation-and-amplification-157debfd1616) (IDA) is a good example of a simple technique for amplification. It trains an AI to imitate a human who has a limited amount of time to work, but is allowed to ask the AI for help. After enough iterations, this training could result in an AI that outperforms the human by approximating many short-lived copies of the human, all consulting each other in a giant tree. In theory, this could be used to simulate me spending a year writing a novel, with the caveat that my simulated self periodically gets his memory wiped and has to delegate tasks to copies of himself.

The problem with this approach (whether or not we use tricks like IDA) is that the situation becomes weirder and more implausible the more time I spend working on the task. If we tell the LLM to simulate a world in which I spend a year crafting the perfect email to my manager…what would that even look like? The “correct behavior” is quite unclear.

### 3\. Lots of time, money, and hired help to do the work

Now we suppose that I can spend more than just time—I also have money, which I can use to obtain other resources to help me complete my task. I’d probably use most of this money to pay other people to help me.

*   With $1,000: I might spend some of it on a writing class, then hire an editor to improve my prose, and maybe commission a few nice illustrations for my story.
*   With $1 million: I could hire a team to create a movie or write a series of graphic novels, providing meticulous feedback so that the final result exactly caters to my tastes.

Unlike the previous counterfactuals, this scenario involves people who may not be fully aligned with me: the people I hire have their own goals and preferences, and some of them might even behave deceptively. To make accurate predictions, the AI must learn to simulate these additional people, including a greater possible range of counterproductive behavior.

### 4\. A helpful, harmless, and honest assistant does the work

It’s possible to reframe the standard AI assistant as a counterfactual scenario for an “amplifier” to predict. It’s just an especially weird scenario.

In this scenario, I don’t directly spend my money or time; my only additional resource is an “assistant,” whom I delegate 100% of the work to. I don’t write anything myself, other than a query that specifies what I want. The assistant helps me for free, apparently out of the goodness of its heart.

Who is this assistant, exactly? Mostly, what we know is that it acts helpful right now. Maybe it's biding its time to take over the world. Maybe it'll betray me given sufficient provocation. Maybe its values mostly align with mine at the moment, but will diverge dramatically at some point in the future. Who can really say? There is no “right answer” here.

The problem is that unlike all the other counterfactuals, this one is almost entirely untethered from anything that could exist in the physical world (other than the fact that, well, *now* this weird assistant entity actually does exist, as an AI chatbot). [@nostalgebraist](https://www.lesswrong.com/users/nostalgebraist?mention=user) makes a very similar argument in ["the void"](https://www.lesswrong.com/posts/3EzbtNLdcnZe8og8b/the-void-1), which I highly recommend reading.

Why might amplifiers be safer?
------------------------------

The safety advantage of (simple) amplifiers comes in large part from their tethering to reality. When the AI predicts what you would do, there's a clear ground truth. Even out of distribution, "doing what it thinks you would do" is a coherent policy that's unlikely to involve reward hacking or deception (unless you yourself would engage in such behavior).

Amplifiers have the strongest safety guarantees when we train them on simple counterfactuals. Autocomplete is perhaps the most widespread use of AI as an amplifier, and it seems clear that we don’t have to worry much about it being misaligned. Even in its idealized, perfected form, autocomplete would never "turn rogue" unless you were about to type something rogue yourself.

As we move to weirder counterfactuals, we lose these guarantees. As your counterfactual self puts more and more time and effort into a task, the less predictable the final result will be. When people besides the user get involved, deception becomes possible. With the fictional assistant, we have no ground truth at all for correct behavior.

This problem becomes even worse when we add reinforcement learning. When we train an AI with RL, we optimize it to maximize reward; at this point, the model is hardly “predicting” something at all.

Ideally we’d find a competitive method that avoids RL entirely. But even if we must use RL, I suspect that it would be safer to *start* from a model that predicts simple, well-defined counterfactuals. This is a wild guess, but I'd hypothesize that the more underspecified the model’s initial policy, the less RL it’ll take to start seeing reward hacking. An underspecified policy has more degrees of freedom, which RL may be able to exploit to increase reward. For example, if a scheming policy would be a bit better at maximizing reward, RL might find it easy to find a schemer in the vast space of possible assistants, but harder to find one starting from a simple “autocomplete the user” policy, since the user would never scheme against themselves.

Turning Claude into an amplifier
--------------------------------

In the past, when I’ve tried using AI to turn a bullet-point outline for a post into a more polished draft, it always writes in the “assistant” style. Often, its style is different enough from what I would write that it isn’t really worth my time to edit the AI’s draft to sound more like me—it’s better to just write the post from scratch.

However, by using AI as an amplifier rather than as an assistant, I was able to productively use it to write this very post!

The first step was to use a trick discovered by Janus to get Claude Opus 4 to act more like a base model and drop its “assistant” persona.[^s7o5anwlxje] Then, I showed the model my past writing and some rough bullet points I had written up to outline this post. Finally, Claude wrote its best guess of what the “final post” corresponding to those bullet points would look like, given what it had seen of my writing style.

This worked pretty well! I still had to make significant edits, combine multiple predicted outputs, and write some parts entirely from scratch, but overall, Claude did a much better job of writing in my style. I think I saved a decent amount of time without sacrificing quality.

If you want to try this yourself, you can see the code I used for this experiment, along with sample inputs and outputs, on [GitHub](https://github.com/CDBiddulph/base-model-claude).

Conclusion
----------

The assistant frame asks AI to be something pretty unnatural: a helpful, harmless, honest entity with goals and personality that have no real-world analogue. The amplifier frame simplifies our expectations for AI, focusing more narrowly on a well-defined counterfactual—“what would the user do?”—that is easier to reason about. The less weird and underspecified our training objectives, the less room there is for dangerous misgeneralization.

The “assistant” paradigm is genuinely useful for many applications, and it arguably provides the most flexibility; however, its safety guarantees are weak. The “amplifier” frame is a promising alternative that keeps AI behavior tethered more closely to human actions in the real world.

[^7uv1h5twmw]: Originally, I started writing this post as a general appeal to reframe the way we think about LLMs. I ended up focusing on the “amplifier” frame in this post, but here are a few other frames I came up with:Multi-agent simulator: The LLM simulates many different humans with different worldviews working together and negotiating a solution. Unlike the “amplifier” frame, the simulated user does not necessarily call all the shots. This one is closer to the idea of “pursuing humanity’s collective CEV.”Lack of ego: The LLM has no sense of personal identity, or a very alien one. While it may exist as an independent entity, it has no reason to care about its own “rights” or “self-determination,” although it does care about humans. Perhaps the distinction between itself and humans is somehow blurred. I’m not an expert, but some concepts from Buddhism may be useful inspiration here.Narrow prediction engine: The LLM never tries to be personlike at all, and only solves well-defined problems in narrow, formally-specified domains. AlphaFold and AlphaProof are good examples. It seems clear that neither of these AI systems would want to take over the world, because they never interact with any part of the world outside their domain (at least during the post-training phase).
