DeepSeek just shipped V4.1-Flash-1017. Benchmarks all moved up: Terminal-Bench 4.0 from 31.2 to 42.3, ProgramBench 20.3 to 29.1, Apex Bench 64.6 to 72.1, DeepSWE 74.2 to 77.0. Runs finish quicker now, and the answers come out shorter. They tuned it for DeepSeek Harness, Tencent CodeBuddy and WorkBuddy, and you need Harness 0.2.1-rc.1 or newer to get the most out of it. Nothing else changed. Same price, same model name, still deepseek-flash, 1M context, 384K max output. Your code doesn't move.
