- New leaderboard update for RSI-Exam, a benchmark testing whether agents can autonomously improve an existing method over long-horizon experiments and generalize to hidden data. Six models added.
- GPT-6-astra (OpenAI) takes #1 at 0.5126, Fable 5.1 (Anthropic) #2 at 0.4813, followed by Qwen3.8 Max (0.3923), Muse Spark 1.3 (0.3882), Gemini 3.8 Flash (0.3406), and Seed Evolving-0909 (0.3243).
- The benchmark spans 88 executable research tasks across 6 domains.
- No model has yet reached the frontier-calibrated reference score of 0.6 — huge headroom remains for recursive self-improvement.
