Robocurve's real-robot benchmark (RoboDojo-RC Tier 1, 120 attempts per model, 95% CIs) shows frontier LLM mean task scores climbing exponentially: the record went from 15% (GPT-5.6 Sol) in July 2026 to 48% (Opus 5.5 XH) by September — roughly doubling every 6 weeks. The chart tracks GPT-6 Astra, Gemini 3.8 Flash, Opus 5/5.5, and GPT-6/6.1 Sol against release dates, suggesting rapid transfer of model capability gains into real robot tasks.
