Metric: Task success rate (%) over the 75 instances whose environment description is 32K tokens long; 15 seed agentic tasks adapted from Toolathlon with five seeded environment states each, on local mock servers (Canvas, email, calendar, BigQuery, Snowflake, WooCommerce, spreadsheets and more); ReAct scaffold, each model at its maximum context window with the oldest context truncated beyond it; success checked by rule-based scripts on the final environment state; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 7 models tracked.
