DeepSeek V4 Flash 0731: frontier intelligence for three cents
Top-tier performance for about US$0.03 per million tokens — and the model is published for download.
It's the latest update to DeepSeek's Flash line — the line designed to be fast and cheap, not the biggest. The result of this version is that the distinction no longer makes sense: it now approaches the full models.
According to the source, it sits one point below GLM 5.2, beats the previous V4 Pro version, and climbs about 10 points over the previous Flash. The gain comes from the DSpark architecture, the same as the previous version, focused on efficiency and throughput.
Why this matters
- Costs about US$0.03 per million tokens — the source estimates it's roughly 100× cheaper than Claude Opus.
+ 2 points on paid plans.

The microcourse
1.Where it wins
3 minThe tests mentioned in the video cover three fronts, and they're exactly the ones that matter to people building things:
- Agentic coding — the model operating tools across multiple steps, not just writing a standalone function.
- Software engineering — real repository tasks.
- Cybersecurity.
It easily outperforms the previous V4 Pro version. In some cases, it even matches or ties with GLM 5.2 or Opus 4.8.
The chart that matters most is performance versus cost. DeepSeek V4 Flash sits in a corner of the chart almost alone; GPT 5.6, Claude Opus, and Claude Fable sit at the opposite end. It's the definition of the best value available today.
