DeepSeek-V4.1-Flash released: open weights trade blows with GPT-5.6 and Claude Opus 5
AccBalanced · x · 2026-09-10
DeepSeek officially released V4.1-Flash, the smallest model in its new architecture family, with native visual understanding and a focus on capability, faster inference, and higher throughput.
- Third-party observation (@nedimagic): as an open-weight model, V4.1-Flash beats GPT-5.6 Sol and Claude Opus 5 on several of DeepSeek's own agentic benchmarks—DeepSWE 74.2 vs 73.0; CyberGym 88.1 vs 84.5; Automation-Bench 54.8 vs 50.3/45.8.
- Caveat: these are DeepSeek's own benchmarks and don't mean universal superiority, but the open/closed gap is collapsing—with near-frontier intelligence potentially downloadable within 12-24 months.
