   DeepSeek releases DeepSeek-V4.1-Flash-1017 open-weight model

   DeepSeek released DeepSeek-V4.1-Flash-1017, an open-weight model that the testingcatalog X post says scores 77% on the DeepSWE 1.1 benchmark, ahead of GLM-5.3, Kimi K3 and models such as GPT-5.6 Sol and Opus 5. The post says the model is available on DeepSeek Chat, the API and HuggingFace, and that it is optimized for DeepSeek Harness and Tencent CodeBuddy. A DeepSeek message quoted in the post claims stronger benchmark performance, faster task completion and shorter outputs than the previous version — a "Pareto improvement in performance and cost" — but the comparisons and the "extremely cheap" description come with no independent verification or pricing figures.
