- resolved-rate; 111 problems from 65 repositories; task window 2026-05-15 to 2026-07-01; model track; configuration Fable 5 [high]; tools interaction mode; minimal ReAct framework; mean resolved rate over five full-benchmark runs; published resolved mean 64.5% with SEM 1.41 percentage points; SEM is standard error of the mean, not a confidence interval or standard deviation; publisher context policy 128K tokens unless the model supports less; developer-recommended default generation settings; declared-model match to Atlas anthropic/claude-fable-5; exact execution backend and API request model identifier unverified; publisher model release date 2026-06-09 is not a measurement date or proof of the Atlas dated execution; publisher flags potential contamination because its model release date follows the task-window start; this is not proof of training contamination; result date not supplied; source captured 2026-09-10
