DeepSeek has released DeepSeek-V4.1-Flash-1017. Updates are now live across the web interface, mobile app, and API. Benchmark results show significant improvements compared to the previous V4.1 Flash version, with faster task execution times and shorter output lengths. The model achieves a new performance-to-cost Pareto optimum across multiple harnesses. We recommend upgrading to DeepSeek Harness 0.2.1-rc.1 or later.
