DeepSeek V4 Flash lifts agent scores 13 points

DeepSeek released V4-Flash-0731 with a Terminal Bench 2.1 score of 82.7, up 20.9 points from the preview’s 61.8 and 10.6 points above V4 Pro Preview, according to the MIT-licensed model card. DeepSeek also reports 54.4 on DeepSWE versus 7.3 for the preview, while leaving the API model name unchanged. The update closes the agentic deficit identified when DeepSeek V4 first paired near-frontier capability with a 98% price discount, but operators should rerun their own harness before treating vendor benchmarks as a drop-in production verdict.
