We ran the largest open experiment on how frontier models do AI research. 100+ autonomous runs across 10+ models, sandboxed on 8xH200s for up to 8 days, iterating on the nanoGPT optimizer track. Best runs closed 82% of the gap to a record built by dozens of humans over months. 590.4K views · 1.9K likes · 213 reposts · 74 replies Open on X →

multi-agent support is live in prime-rl + verifiers you can now train and eval setups like: - Agentic Judging — solver traces are graded by a judge - Self-Play — a model playing against itself - User-Sim — a user agent interacting with an assistant https://t.co/Zvy44y9WJP 21.1K views · 242 likes · 14 reposts · 7 replies Open on X →

We've raised $130M to build the Open Superintelligence Stack and make frontier AI infrastructure, once locked behind the walls of the big labs, accessible to every company. https://t.co/oU1yDtZwKe 20.5K views · 233 likes · 13 reposts · 33 replies Open on X →
