The part that stood out to me is how the agent's search strategy changed qualitatively with parallelism, not just quantitatively. Sequential search forces greedy hill-climbing. Parallel search lets you run factorial grids and catch interaction effects between parameters. That's a fundamentally different kind of exploration.
We see the same pattern with multi-agent systems in production. A single agent doing tasks sequentially develops tunnel vision — it commits to an approach early and optimizes locally. Give it the ability to explore multiple paths simultaneously and the quality of decisions changes, not just the speed.
The H100/H200 discovery is a nice example of this. Sequential agent would never develop a two-tier validation strategy because it would never run the same config on two different GPUs at the same time to notice the difference.
I feel like most of this recent Autoresearch trend boils down to reinventing hyper-parameter tuning. Is the SOTA still Bayesian optimization when given a small cluster? It was ~3 years ago when I was doing this kind of work, haven't kept up since then.
Also, shoutout SkyPilot! It's been a huge help for going multi-cloud with our training and inference jobs (getting GPUs is still a nightmare...)!
Wrong and short-sighted take given that the LLM explores serially learning along the way, and can tool use and change code arbitrarily. It seems to currently default to something resembling hyperparameter tuning in absence of more specific instructions. I briefly considered calling the project “autotune” at first but I think “autoresearch” will prove to be the significantly more appropriate name.
Out of curiosity, what sort of things have you seen it do that better fit 'autoresearch' than 'autotune' thus far? Optimizations it made that wouldn't be been surfaced by an autotune system, I suppose.
Does the agent have access to arxiv (a brief skim of the README didn't have an answer)? If not, it could be that the current approach of relying on the model's weights only is resulting in the perceived local optimum of hyperparameter tuning.
Anecdotally, we built a little MCP for arxiv to help with our internal research, noticed a significant boost in the diversity of methods (architecture or otherwise) Claude and friends were able to reference.
Would you say it's fair to describe autoresearch as a form of neural architecture search? I am curious what you think the core differences are between them.
Have you actually used LLMs for non trivial tasks? They are still incredibly bad when it comes to actually hard engineering work and they still lie all the time, it's just gotten harder to notice, especially if you're just letting it run all night and generate reams of crap.
Most people are optimizing for terrible benchmarks and then don't really understand what the model did anyone and just assume it did something good. It's the blind leading the blind basically, and a lot of people with an AI-psychosis or delusion.
Hm, that's fair. It does feel like there's low hanging fruit in combining "old school" methods for conducting a hyperparameter sweep efficiently _with_ the higher level architecture edit ability of Autoresearch.
Probably would cut the number of runs down by a significant number (as far as I can tell it's doing a grid search once it decides to mess with a knob or section of the architecture).
> How parallelism changed the agent’s research strategy
> With a single GPU, the agent is stuck doing greedy hill-climbing: try one thing, check the result, pick a direction, try the next thing. With 16 GPUs, the strategy shifts. ...skip... 12 experiments in a single 5-minute wave. This makes it much harder to get stuck in local optima and much easier to find interaction effects between parameters.
The agent can theoretically come up with a protocol to run those same 12 experiments one-by-one and only then decide which branch to explore next - which I think would lead to the same outcome?
But in this case, it just happened to have stumbled on this particular outcome only because it didn't get a chance to execute a greedy strategy after the first 1 or 2 results.
The most surprising part: the agent had access to both H100s and H200s. Without being told, it noticed H200s scored better and started screening ideas on H100s, then promoting winners to H200s for validation. That strategy emerged entirely on its own.
In this case, using a cheap(er) signal or heuristic as an initial filter before spending more resources on cases that pass the filter is a pattern that shows up all over the place, and LLMs are good at picking up on patterns like that and generalizing them. AFAICT.
Is your assertion that no one has ever written "we tried some stuff on the small inexpensive platform first, then moved to the bigger more expensive platform with the more promising options" in a research paper or literally anywhere else?
Why?… The experiment.yaml shows that it is calling h100/200 explicitly, it’s pretty common for humans to say “number bigger more gooder” for anything… Lie and reverse the values and see what happens. I would put money on a rabbit hole of complaining about it being misconfigured.
I am fascinated by this example of using AI to improve AI. I won a small prize using this technique on helion kernels at a pytorch hackathon in SF.
The next step are:
- give the agent the whole deep learning literature research and do tree search over the various ideas that have been proposed in the past.
- have some distributed notepad that any of these agents can read and improve upon.
Human-driven research is also brute-force but with a more efficient search strategy. One can think of a parameter that represents research-search-space-navigation efficiency. RL-trained agents will inevitably optimize for that parameter. I agree with your statement insomuch as the value of that efficiency parameter is lower for agents than humans today.
It's really hard to imagine that they __won't__ exceed the human value for that efficiency parameter rather soon given that 1. there are plenty of scalar value functions that can represent research efficiency, of which a subset will result in robust training, and 2. that AI labs have a massive incentive to increase their research efficiency overall, along with billions of dollars and really good human researchers working on the problem.
Wait, "Karpathy's Autoresearch", you mean a loop that prompts the agent to improve a thing given a benchmark?
People have been doing this for a year or more, Ralph loops etc.
I hate the weird strange Twitter world of hero-worship for folks that seems to arise just out of large followings.
Joe no-followers does this six months ago, nobody cares. Karpathy writes a really basic loop and it's now a kind of AI miracle prompting tons of grifters, copy-cats, weird hype.
I do wonder if LLMs have just made everyone seriously, seriously dumber all of a sudden. Most of the "Autoresearch" posts I see are completely rubbish, with AI optimizing for nonsense benchmarks and people failing to understand the graphs they are looking at. So yes, the AI made itself better at a useless benchmark while also making the code worse in 10 other ways you don't actually understand.
The number of refurbished mac minis that are available in my country has suddenly dramatically increased ever since the Clawdbot tweet. People never learn.

Worse experiment design + parallelism = better experiment design + serialized execution ?

> Why surely? Have you never seen an LLM try something new?
I'm afraid I can't make it any simpler than this.
And I still don't know the answer to how you're so sure. To me there's several explanations, and it seems to you there's only one.
I'm pretty happy with my communication style.

All of science is "gather inputs, make hypothesis, test, analyse" on repeat.
There's plenty to critique in the particular guidance approach, but the overall method is the same.
