DeepSeek V4 Flash 0731 release highlights stronger agentic ability and low cost
Simon Willison
EDITOR BRIEF
The latest model in DeepSeek’s V4 family is described as having much stronger agentic abilities. It has 304 billion parameters and is said to score well on an intelligence-vs-cost chart, with pricing of $0.14 per million input tokens and $0.27 per million output tokens. The excerpt also notes that higher reasoning settings produced a better result than the default.
INSIGHTS
This shows that a model’s settings can affect output quality as much as its size or price. If you are learning AI, try comparing the same prompt with different reasoning levels to see how behavior changes.
