DeepSeek V4 Flash 0731
DeepSeek V4 Flash 0731 is the official production release of DeepSeek's efficient 284-billion-parameter, 13-billion-active Mixture-of-Experts model, replacing the April 2026 preview build. The "0731" suffix marks a pure re-post-training pass — same architecture and weights structure, dramatically stronger agentic behavior.
Released July 31, 2026, it jumped from 61.8 to 82.7 on Terminal-Bench 2.1 and from 1,189 to 1,559 Elo on GDPval-AA v2, closing in on Claude Opus 4.8 while undercutting GPT-5.6 Luna by roughly 60% at $0.14/$0.28 per million tokens, with MIT-licensed weights on Hugging Face.
Think of it as a factory retooling the same assembly line overnight instead of building a new factory.

Why is it emerging now?
DeepSeek's July 31, 2026 re-post-trained release nearly triples its Terminal-Bench 2.1 score to 82.7, landing within striking distance of Claude Opus 4.8 while undercutting OpenAI's just-discounted GPT-5.6 Luna by roughly 60% per task — a fresh escalation in the AI price war that a 734-point Hacker News thread greeted within hours.

Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
Self-reported vendor benchmarks dominate the SERP; the first third-party run on real agentic tasks owns this query cluster.
Explains the 98% cache-hit discount, $0.14/$0.28 base rates, and break-even math against Luna's post-discount pricing.
Same architecture, different post-training — no tutorial yet explains what output-quality regressions to check for.
Re-post-trained checkpoints can silently shift behavior on production prompts; a diff harness is an immediate ops need.
Officechai's Opus-4.8 comparison has no video counterpart yet; a live demo drives affiliate API-referral clicks.
OpenAI slashed GPT-5.6 Luna prices 80% on July 30. DeepSeek answered less than 24 hours later with a free re-post-train that closed half the remaining gap to Claude Opus 4.8.
DeepSeek didn't retrain V4 Flash from scratch — it just re-post-trained the exact same 284B-parameter checkpoint and nearly tripled its coding-agent score.
