🤯 DeepSeek V4.1 Flash just gained 11.1 percentage points on Terminal-Bench 4.0 in a "minor update." The new 1017 version brings some serious benchmark jumps: Terminal-Bench 4.0: 31.2% → 42.3% ProgramBench: 20.3% → 29.1% DeepSWE: 74.2% → 77.0% Automation-Bench: 54.8% → 60.5% It even beats GPT-5.6 Sol on Terminal-Bench in DeepSeek's tests. And the crazy part? Same API pricing, shorter outputs and reportedly faster task completion. Open weights. MIT license. Already live.
