Nathan Lambert Launches Nonprofit Trillium Labs for Open Frontier AI Science
On October 3, AI researcher Nathan Lambert (formerly of Hugging Face and AI2) announced the co-founding of a nonprofit, Trillium Labs, with longtime collaborator Tom Zick, focused on open science in frontier AI. The news was covered by Wired.
Confirmed
- Trillium Labs is a nonprofit organization co-founded by Nathan Lambert and Tom Zick, with the official account @trilliumlabs.
- Its first priority is building and releasing open post-training recipes.
- Plans include expanding into open-source infrastructure.
- Research directions include RSI, reward hacking, and multi-agent systems.
Why it matters
- Post-training recipes are a key differentiator for frontier model competitiveness, and major labs rarely disclose details. If Trillium Labs keeps open-sourcing this work, it could significantly lower the barrier to replicating frontier capabilities.
- Lambert has long shared insights on post-training techniques publicly (e.g., his technical newsletter), and institutionalizing this effort as a nonprofit could make Trillium Labs a vital resource for the open-source community in the post-training era.
