We're working directly with frontier-lab researchers to do this work with bleeding-edge models.
We expect to produce many more blog posts like this as our research program grows symbiotically with our RL-env work.
And we're hiring :)

I've shifted my research to focus on automated alignment research. We will have automated AI research very soon and it's important that alignment can keep up during the intelligence explosion.
We estimate that, on our tasks, Claude Opus 4.5 has a 50%-time horizon of around 4 hrs 49 mins (95% confidence interval of 1 hr 49 mins to 20 hrs 25 mins). While we're still working through evaluations for other recent models, this is our highest published time horizon to date.

I'm doing research @d_model_ai now! Very excited about the team and mission. We're teaching computers to teach computers to teach computers to be good people.

the true value in AI coding nowadays isn’t in writing code, it’s in reading code: outlining large code bases, navigating, retrieving suggestions & ideas, and breaking down and explaining tricky concepts
i’ve never had a more complete understanding of codebases before
I am learning that I am an unusual CEO in many ways. Some know that I still code on nights and weekends (github.com/lattner) despite a busy “day job”.
As part of that, I care deeply about sw development as a profession, and what “AI anxiety” is doing to many early and experienced developers.
IMO, AI is here to stay, super useful today for things, and will continue to improve… but is far from SWE job displacement. It is sad for me to see many talented people giving up hope and sabotaging their own career development because of a future that may not actually arrive!
Please watch the video for a much more nuanced discussion about the issues involved, particularly if you are an early career engineer who wants to make a big impact on things!!

📢 Can LLMs really reason outside the box in math? Or are they just remixing familiar strategies?
Remember DeepSeek R1, o1 have impressed us on Olympiad-level math but also they were failing at simple arithmetic 😬
We built a benchmark to find out → OMEGA Ω 📐
💥 We found that although very powerful, RL struggles to compose skills and to innovate new strategies that were not seen during training. 👇
