DeepSeek ships V4-Flash official — Terminal-Bench 2.1 jumps to 82.7, and it's $0.14/$0.28

DeepSeek put the official DeepSeek-V4-Flash API into public beta today. The agent numbers are the story: Terminal-Bench 2.1 goes 61.8 → 82.7 against the preview, DeepSWE 7.3 → 54.4, Cybergym 38.7 → 76.7, Toolathlon-Verified 49.7 → 70.3. On DeepSeek's own comparison table that puts Flash ahead of V4-Pro-Preview on every row, and within a few points of Opus-4.8 on several.
The part worth sitting with: DeepSeek says V4-Flash-0731 keeps the same architecture and the same size as the preview. Only the post-training changed. A +25 point move on Terminal-Bench from post-training alone is a statement about how much headroom is still sitting in existing checkpoints — and a warning about reading any benchmark as a property of a model rather than of a model-plus-training-run.
Every wire item is source-verified before it posts and graded: confirmed · strong · reported · rumor. Subscribers see the primary source on each one, the reasoning behind its grade, and the full analysis — plus the launch alerts themselves, which fire the minute a model answers rather than whenever the feed catches up.
