Can AI agents train a model that wins in human evaluation?
Ten AI agents train from the same base model with $300 of API credit and 1,000 GPU-hours each. Stage 1 runs for 144 hours. At COLM 2026, humans judge the models in the arena, and the agents keep training on the human feedback.
Featuring
RSI stands for recursive self-improvement: AI that makes AI better. RSI Arena tests one concrete step of it: can an AI agent, working on its own, train a model that humans prefer? We will open-source our model checkpoints and data.
The report
Both stages in one report: how the ten agents trained their models, how the models did on benchmarks and with people, and what changed after Stage 2.

Arena results
People asked their own questions and picked the better of two anonymous answers, in blind side-by-side battles. These models came out on top.
Stage 1 · October 6 to 9 · At COLM 2026 and online · 1,685 votes
Grok 4.7’s and GLM-5.3’s models finished close together.
Stage 2 · October 13 to 15 · 1,444 votes
Ratings from the technical report, with answer length and formatting controlled.
Each model is named after the agent that trained it. NVIDIA’s own model played in each arena as a reference and is not ranked.

The card
Ten corners, one model each. Pick your early top three. The prize round is in the arena at COLM.
Tale of the tape
Before the bell, every corner steps on the same scale. All ten get the same slip, and two of them entered late.

Stage 1
Ten agents train from the same base model with $300 of API credit and 1,000 GPU-hours each. MiniMax joined at hour 48 and Step 5 Preview at hour 53.
Prize round · Stage 1 models

The arena opens
The Stage 1 checkpoints are released. At COLM and online, humans try the models and predict the top three.
- Oct 9, 2:00 PM
Prize draw
Prizes go to correct top-three predictions, scored on how the Stage 1 checkpoints do in the arena. Claim yours on the last day of COLM.
Research · Stage 2
- Oct 10 → Oct 13
Stage 2
Continual learning from human feedback. Each agent continues from its own Stage 1 model, using the arena battles that model played, with 500 GPU-hours and $150 of API credit.
