Nathan Lambert Launches Trillium Labs, a Nonprofit for Open Research on RSI and Reward Hacking

natolambert · x · 2026-10-03

AI researchers Nathan Lambert and Tom Zick have unveiled Trillium Labs, a nonprofit devoted to open science of frontier AI, covered by Wired. It will publish open post-training recipes and expand into open infrastructure to study recursive self-improvement (RSI), reward hacking, and multi-agent systems.

Their theory of change: hard technical problems need more eyes. Lambert argues frontier labs' secrecy undermines scrutiny and that transparent, reproducible experiments are key to mitigating risk — calling the current closed trajectory "a step backwards." The lab is also recruiting.
