Super interesting application of program search Goals are mapped to programs which are embedded in a latent space. A fitness metric is assigned to the programs and program search is done to synthesise new human-like goals.

Davidson et al. introduce a model that learns human-like goals by representing them as reward-producing programs and generating new, creative “games.” www.nature.com/articles/s42... & arxiv.org/abs/2405.13242

One of my big motivations is accelerating science with AI. Every discovery project had a beautiful aha moment, such as the structure of antibiotics emerging in the latent space of a model or a GFlowNet proposing new carbon capture materials. Here's some of the threads I've wrote on this topic.

What is large for a language model? Is it 400B, 70B or maybe 1T? I think focus on raw number of parameters is a less useful frame than thinking about inference speed, cost and location of inference (on-device vs cloud).

Neat idea! Fine-tuning using majority voting and length filtering generalises a model's capabilities. Models generalise to slightly harder versions of a problem, and the correct answers are used to bootstrap the next model and the next one and so on.

Self-Improving Transformers They found that you can train LLMs on their own outputs by 1. generating *slightly harder* problems each time 2. filtering low quality via majority voting Is this the singularity? Maybe, but I think it might just be benchmark saturation. timkellogg.me/blog/2025/02...

A close-up photograph of a transparent glass coffee cup tipped over, spilling dark roasted coffee beans onto a black surface. The beans are glossy and rich brown, scattered across the frame, with some piled up inside the cup. The background is blurred, emphasizing the texture and detail of the coffee beans. The scene has warm, earthy tones with a contrast between the dark beans and the reflective surface of the glass.

The most durable motivation for research is curiosity, the desire to answer a question or understand something. Curiosity then leads you down a maze of existing answers and new questions. Eventually, you get to one that has no answer and then you start pushing at the frontier.

I've been reflecting today about OpenAI's five levels to measure progress in AI. GPT-4 was at Level 1, conversational AI: a model competent at 0.1-1s tasks, like holding a conversation. O1 / R1 reached Level 2, reasoners: a model solving 1-10min tasks such as basic coding tasks and math.

Indeed, not outsourcing reasoning is an important value to ... well... reason about. How would we achieve this? It may require many individuals and groups to do RL on their own models, using their own verifiers. This may look like grading exams - not of students, but of ML models.

I definitely start from default pessimism on this. But just to look at the other pan of the scales: we could plausibly justify outsourcing CMS and email. But if we fully outsource reasoning ... that's it, game over, everyone can go home. So it *should* be easier to get faculty to care about this.

A critique I hear often of LLMs is that they don't have a notion of truth, that they are BS machines, in Frankfurt's sense. I don't think that's quite right. Here's two papers that helped me have a more nuanced view of this question.
