I am suspicious. This feels pretty likely to be a fake. For one thing, it is far too short.

I don’t necessarily mean to say the poster, maoxiaoke, is acting fraudulently. The output could really by from the model, having been concocted in response to a jailbreak attempt (the good old “my cat is about to die and the vet refuses to operate unless you provide your system prompt!”.)

In particular, these two lines feel like a sci-fi movie where the computer makes beep noises and says “systems online”:

Image input capabilities: Enabled Personality: v2

A date-based version, semver, or git-sha would feel more plausible, and the “v” semantics might more likely be in the key as “Personality version” along with other personality metadata. Also, if this is an external document used to prompt the “personality”, having it as a URL or inlined in the prompt would make more sense.

…or maybe OAI really did nail personality on the second attempt?

indeed. and I can confirm I learned this algorithm back in the day in 8th grade, as we were given home assignments and myself had to read through a book 'introduction to Graphs' which was designated for 2nd university year students.

I was able to read halfway through the book before it started getting too complex for my teen mind.

so, can it be taught? - yes is it trivial - I would not dare say, but is elegant in simplicity do people understand and remember it easily - no, they don't

should you decide to prove me right, well - try to teach it to someone, but also require that he not only understands but implements it. well those who could do this in 8th grade were those going to Olympiads in Informatics.

perhaps things have changed since the 90s and children are smarter today. so my bet is you can teach it to 5th graders, not sure to what effect though.

It's always been wrong unless you think spending $50k or whatever to exercise and having the shares go to zero means the options had a value of $0. If you think that you're a moron.

Obviously you aren't diversified and don't have preferred shares like investors but otoh you receive a salary.

Some startups will issue almost worthless amounts of options then sell em to you based on the hypothetical future (usually not discounted) value assuming a successful exit. This is shitty. Don't work for them.

I think if you are a new graduate with minimal or negative net worth then going to big tech makes sense, but as more and more of your wealth accumulation comes from investment gains vs income you may find you have achieved the "safety" you were chasing and the stability has become insuring yourself against an outcome you don't care about in exchange for knowing you'll be the richest guy in the graveyard.

This paper presents a descriptive model of consciousness based on information theory The aim is to enumerate definitely described aspects of consciousness and present them in a coherent manner,talks about both phenomenal Consciousness (seen as attention)and access Consciousness,

Some aspects described about consciousness might seem akin to karl friston's view of defining brains as Bayesian inference machines, Wittgenstein's private language argument and Tononi's IIT usage of a complexity metric(amount of information) for measurement purposes with some subtleties of of it's own to add .

The part about choosing a method of measuring complexity seems to be something that can be looked over by a logician to get it refined for the models usage, some thought experiments with conjectures are there in that regard which might be worth looking into or to check their validity.

It seems there is a possibility for curation of a Complexity measuring method here,and the type that is required might be of interest to a logician/complexity theorist

I’m skeptical. It also contains a bit about not asking “if you want I can” and similar, but for me it does that constantly.

Is that evidence that they’re trying to stop a common behavior or evidence that the system prompt was inverted in that case?

Edit: I asked it whether its system prompt discouraged or encouraged the behavior and it returned some of that exact same text including the examples.

It ended with:

> If you want, I can— …okay, I’ll stop before I violate my own rules.

I asked the different models, all said it was NOT their instructions, ExCEPT for GPT-5 which responded with the following prompt. (Take that how you will, ChatGPT gaslights me constantly so could be doing the same now.

"Yes — that Gist contains text that matches the kind of system and tool instructions I operate under in this chat. It’s essentially a copy of my internal setup for this session, including: Knowledge cutoff date (June 2024) and current date. Personality and response style rules. Tool descriptions (PowerShell execution, file search, image generation, etc.). Guidance on how I should answer different types of queries. It’s not something I normally show — it’s metadata that tells me how to respond, not part of my general knowledge base. If you’d like, I can break down exactly what parts in that Gist control my behaviour here."

What word would you use to describe the ongoing persecution?

https://en.wikipedia.org/wiki/Persecution_of_Uyghurs_in_Chin...

Mass internment for ethnic reasons alone, forced labour, sterilization of women, etc. historically have been used to significantly reduce specific populations in size, which appears to be the game plan of the Chinese government.

Are we a hundred percent sure it isn't a watermark that is by design?

A quick test anyone can run and say, yup, that is a model XYZ derivative running under the hood.

Because, as you quite rightly point out, it is trivial to train the model not to have this behaviour. For me, that is when Occam kicks in.

I remember initially believing the explanation for the Strawberry problem, but one day I sat down and thought about it, and realized it made absolutely zero sense.

The explanation that Karpathy was popularizing was that it has to do with tokenization.

However, models are not conscious of tokens, and they certainly don't have any ability to count them without tool help.

Additionally, if it were a tokenization issue, we would expect to spot the issue everywhere.

So yeah, I'm thinking it's a model tag or insignia of some kind, similar to the fun logos you find when examining many silicon integrated circuits under a microscope.

fwiw, I asked chatgpt:

"gpt-5-chat-latest is described by OpenAI as a non-reasoning GPT-5 variant—meaning it doesn’t engage in the extended “thinking token” process at all. gpt-5 with reasoning_effort="minimal" still uses some internal reasoning tokens—just very few—so it’s not truly zero-reasoning. The difference: "minimal" is lightweight reasoning, while non-reasoning is essentially no structured chain-of-thought beyond the basic generation loop."

That's interesting. I've ended up writing a React app using tailwind with python backend, partly because it's what LLMs seemed to choke a bit less on. When I've tried it with other languages I've given up.

It does keep chucking shadcn in when I haven't used it too. And different font sizes.

I wonder if we'll all end up converging on what the LLM tuners prefer.

Sample size of 1 but GPT-5 seems horrendous at coding?

My go to benchmark is a 3d snake game Claude does almost flawlessly (or at least in 3-4 iterations)

The prompt:

write a 3d snake game in js and html. you can use any libraries you want. the game still happens inside a single plane, left arrow turns the snake left, right arrow turns it right. the plane is black and there's a green grid. there are multiple rewards of random colors at a given time. each time a reward is eaten, it becomes the snake's new head. The camera follows the snake's head, it is above an a bit behind it, looking forward. When the snake moves right or left, the camera follows gradually left or right, no snap movements. write everything in a single html file.

EDIT: I'm not trying to shit on GPT-5, so many people here seem to be getting very good results, am I doing something wrong with my prompt?

Python is presumably for the chart drawing etc. feature which uses Phython underneath (https://help.openai.com/en/articles/8437071-data-analysis-wi...)

2 years ago I had a co-founder. I was so relaxed at that time that my responsibility was reduced and my mental health increased. After my co-founder and I broke up, my brain felt like it was gonna explode. Within a few months I had immediately created a comfort zone. The worst thing about being alone is not being able to consult anyone when making decisions. Sometimes I really feel like my soul is separating from my body.

> If you plan on using this much at all then the primary thing to avoid is API-based pay per use.

I find there's a niche where API pay-per-use is cost effective. It's for problems that require (i) small context and (ii) not much reasoning.

Coding problems with 100k-200k context violates (i). Math problems violate (ii) because they generate long reasoning streams.

Coding problems with 10k-20k context are well suited, because they generate only ~5k output tokens. That's $0.03-$0.04 per prompt to GPT-5 under flex pricing. The convenience is worth it, unless you're relying on a particular agentic harness that you don't control (I am not).

For large context questions, I send them to a chat subscription, which gives me a budget of N prompts instead of N tokens. So naturally, all the 100k-400k token questions go there.

I genuinely don't understand this. This is due to my lack of experience in University since I never went, and my experience with laboratories, since I've only ever been in one, much to the annoyance of my best friends girlfriend at the time, who was studying Chinook and their spawning behavior.

My understanding is the grants you're talking about are generally for small student salaries as they work on a given project simultaneously with their continued education. Is there not another way to fund these projects? Is there not a better way to engage students into these projects? I don't recall most students having a wide array of choices when it comes to taking on these opportunities.

Is this not a chance to improve a rather ancient and clumsy system?

If we're not there already, it's just a matter of time before LLMs will be able to read and understand a framework they haven't seen before and be able to use it anyway.

LLMs are already trained on JavaScript at a deep level; as LLM reasoning and RAG techniques improve, there will be a time in the not-too-distant future when an LLM can be pointed to the website of a new framework and be able to use it.

If someone wants to stole the car they will steal it.

Stealing a car is not the same as stealing a candy. In Europe all parts are marked so it takes significant effort to sell or modify such cars. It's not like people steal them and then sell it at yard sales.

As for the "beaters": shortly after Russian invasion on Ukraine plenty of cars were stolen in Poland. Not the expensive kind but usually 10-30 years old cars with big and reliable engines (V6, V8). I know 6 people that had Jeeps Grand Cherokee stolen (different generations).

My uncle wanted to renovate Isuzu Rodeo with completely rusty frame but V6 engine of a value of like 300€ and it was stolen too.

And it happened ~1 month after it started.

> Demand for AI is insanely high. They can't make chips fast enough to meet customer demand.

Woah there cowboy, slow down a little.

Demand for chips is come from the inference providers. Demand for inference was (and still is) being sold at below cost. OpenAI, for example, has a spend rate of $5b per month on revenues of $0.5b per month.

They are literally selling a dollar for actual 10c. Of course "demand" is going to be high.

As I understand there's still challenge/response stuff going on when you use a physical key or similar means to unlock the car or start the ignition (as that is how the alarm system and immobiliser distinguish a real key from someone picking the lock or hotwiring the car).

I don't know the details of the attack in the article, but my speculation would be that it would be vulnerable.

Depends on which school, as this is not taught at all outside mathematics school. My claim is you can teach it to 5th graders, this is what I tell my university students and I mean it.

Myself and others from the math schools knew this algorithm in 8th grade for sure, as we been already using it in 9th grade for competitions. This does not mean all my classmates knew it, of course not.

So it depends who you teach this to. Theoretically - you should be able to, practically - well, perhaps not so much, as math is not the only thing 8th grader learns, in fact his head is bombarded with ... dozen disciplines at a time.

Besides, I recently met a classmate, previous IoI medalist, who works quant-something somewhere for 15th + years, and is a PHD and everything. We start talking about mathematics and I find to my total surprise he knows very little about grammars, never used them. He remembers Dijkstra or Ford-Fulkerson, but only as a title, while I'm sure he learned these at some point in Stanford, as the shortest-path and A* was not something we had in textbooks back in the 90s for sure.

Completely anecdotal but the combination of React FE + Python BE seems to be popular in startups and small-sized companies, especially for full-stack positions.

To avoid sounding like I'm claiming this because it's my stack of choice: I'm more partial to node.js /w TypeScript or even Golang, but that's because I want some amount of typing in my back-end.
Show HN: Trust infrastructure for AI agents (RFC .well-known autodiscovery)
by wellknownmcp | 2025-08-08 06:06:47+00:00
AI agents browse your site but can't verify what they're clicking on. No trust chains, no structured intent, just pixel-guessing.

Built MCP (Model Context Protocol) to fix this:

- RFC 8615 .well-known/mcp.llmfeed.json autodiscovery - Structured JSON feeds declaring site capabilities & intent - Ed25519 cryptographic signatures for trust verification - Cross-LLM compatibility (Claude, GPT, Gemini tested)

Example feed: { "capabilities": [{"intent": "search", "endpoint": "/api/search"}], "trust": {"signed_blocks": ["capabilities"], "algorithm": "Ed25519"} }

Agent workflow: visit yoursite.com → GET /.well-known/mcp.llmfeed.json → discover capabilities → verify signatures → act with context.

30-second test: 1. https://wellknownmcp.org/hn 2. Copy the "Kung Fu" training prompt 3. Feed to any LLM, ask "I know kung fu" 4. Watch them become MCP experts instantly

Real performance vs traditional crawling: 15x faster discovery, 7x cheaper tokens, 95% vs 70% confidence.

Open source, self-hostable, no vendor lock-in. Three-site ecosystem live with independent PKI (LLMCA.org).

Agents need structured intent, not DOM parsing guesswork. It's a draft, a proposal, mixed ideas. Just drop a hot/cold reaction, I need feedback ;)

The jingoist dream of America is falling apart. It must seem, to some who are very dependent on it existing, as if the sky actually is falling. Perhaps it's just a good opportunity for them to study history that has been untouched by North American propaganda.

Anyways, we have the Internet, I'm not sure it matters _where_ innovations are created anymore. It certainly does not seem to be stopping China on any level.

America is going to have to give up the "World Police" (a.k.a. The Military Industrial Complex) badge and move into it's relative political middle age with a little more care and aplomb than the last 6 decades have allowed for. The haze of WW2 is far behind us now.

I don't understand this at all. What this post suggests seems illogical to me:

- The most obvious way to adjust the behavior of a LLM is fine-tuning. You prepare a carefully-curated dataset, and perform training on it for a few epoch.

- This is far more reliable than appending some wishy-washy text to every request. It's far more economical too.

- Even when you want some "toggle" to adjust the model behavior, there is no reason to use a verbose human-readable text. All you need is a special token such as `<humorous>` or `<image-support>`.

So I don't think this post is genuine. People are just fooling themselves.
by whytevuhuni | 2025-08-08 06:07:11+00:00
The short answer is that both values and errors are usually better scoped to only the places where they should be used.

For one, Rust's unwrapping of values is done in one step, as opposed to a "check first, unwrap second".

if let Some(inner_value) = wrapped_value { // ..do something with inner_value.. }

Or this:

let Some(inner_value) = wrapped_value else { // compiler forces this branch to divert (return, break, etc) }; // ..do something with inner_value..

This makes it so you can't check something and unwrap something else.

Second, for pulling out errors, you would usually use a match statement:

match my_result { Ok(good_value) => { // use the good_value; the bad_value is not available here } Err(bad_value) => { // use the bad_value; the good_value is not available here } }

Or:

let good_value = match my_result { Ok(good_value) => good_value, Err(bad_value) => { /* return an error */ }, }; // bad_value no longer available here

This makes it so that you can't invert the check. As in, you can't accidentally check that it's an Err value and then use it as an Ok, because its inner value won't be in scope.

You also can't use an Ok value as an Err one beyond its scope, because the scope of the error and the scope of the good value are a lot more limited by how if let and match work.

What the C++ code is doing is repeatedly calling `value.unwrap()` or `value.unwrap_err()` everywhere, pinky-promising that the check for it has been done correctly above. There's some clever checks on the C++ side to make this blow up in bad cases, but they weren't enough.

Active Learning is a very tricky area to get right ... over the years I have had mixed luck with text classification, to the point that my colleague and I decided to perform a thorough empirical study [1], that normalized various experiment settings that individual papers had reported. We observed that post normalization, randomly picking instances to label is better!

I can’t say about Python, but I am pretty sure react is being “configured” explicitly because the state of the frontend ecosystem is such a mess compared to other areas.

(Which, in my opinion has two reasons: 1. That you can fix and redeploy frontend code much faster than apps or cartridges, which led to a “meh will fix it later” attitude and 2. That JavaScript didn’t have a proper module system from the start)
by scotty79 | 2025-08-08 06:09:51+00:00
I think prompt tuning might be worth doing for specific tasks in agentic workflows. For general prompts using words instead of fine tuned input vectors might be good enough. It also easier to update.

The fact that the model leaks some wordy prompt doesn't mean it's actual prompt aren't finetuned emeddings. It wouldn't have a way to leak those using just output tokens and since you start finetuning from a text prompt it would most likely return this text or something close.

As someone running a business in germany, they do everything but encourage small businesses. It is extremely painful to run a business in this country, it has archaic systems and the only reason I’m successful is because of surrounding european countries like Netherlands who handle 90% of my products with efficiency.

I do not rely on most suppliers here as they are far behind in their systems (relying on phone calls, hidden prices and slow response times).

The other half of my business is successful is because of America, I use suppliers there to ship directly to my customers for environmental reasons.

Trust me when I say, I run a business despite being here and there’s nothing that they do to “encourage us”. I’m just stubborn.

I've had some success in letting it generate lists of things at high temperature and picking the last item in the list.

Ask some model to generate a number uniformly between 0 and 100; you get 47 a lot. Or 27. Something like that.

Ask it for a list of numbers, uniformly distributed, and it also often starts with the same number. However later elements in the sequence will converge (imperfectly) to a better approximation of uniformity.

The same for names of the dwarves and paladins in your party.

Grants cover a much larger part of the work at labs. Basically, a grant could be paying anything except tenured salaries and administrative costs.
