From Berkeley robotics and OpenAI's 2017 Dota-era internship to shipping RL breakthroughs on GPT-4o, o1, and o3, and now leading model development at Cursor, Ashvin Nair has done it all. We caught up with Ashvin at NeurIPS 2025 to dig into the inside story...

Highlights

In this conversation, Ashvin Nair traces his evolution from robotics to the forefront of language model development, offering a candid look at the shifting landscape of AI research and deployment. He reflects on pivotal moments in his career and the broader industry, revealing how expectations, methodologies, and organizational structures have adapted—or failed to adapt—to rapid technological change.
00:00
Robotics people are more grounded than other AI researchers.
14:27
OpenAI has abandoned the 'one model fits all' approach as of this year.
17:08
The current reasoning paradigm in AI may stem from organizational misalignment rather than technical limits.
29:32
Human-level intelligence might be reached around 2030.
39:23
Learning from a small number of deployment tokens doesn't overload a model trained on trillions.
42:10
Why is Off-policy RL unstable? is suggested as a strong interview question.
