Why Open Science Is Dying at Frontier AI Labs | Nathan Lambert

Nathan Lambert's new nonprofit Trillium Labs aims to rebuild open AI research infrastructure as closed labs pull ahead on post-training and RL.

• Trillium Labs launches: Nathan Lambert (ex-Allen Institute for AI, Olmo/Tulu lead) starts a nonprofit to build 'research infrastructure'—training recipes, model checkpoints, RL rollouts, and data—so academics can study frontier techniques without needing hundreds of billions in compute.
• Academia's resource gap: Lambert argues universities can still innovate conceptually but can't match closed labs' scale; PhD students and professors increasingly leave for industry, thinning the talent pipeline.
