DeepSeek-V4.1-Flash posts best open-source Boeing benchmark run, sustaining hours-long agentic loops

victormustar · x · 2026-09-11

Indie developer victormustar reports DeepSeek-V4.1-Flash delivered the best open-source Boeing benchmark result he has seen: running for hours with /goal, it kept iterating — inspect, spot a defect, zoom in, diagnose, fix, repeat — where other models stall quickly, showing rare long-horizon persistence. Third-party hands-on, not an official release.
