DeepSeek released DeepSeek-V4-Flash-0731 on July 31, 2026, improving agentic and coding performance through re-post-training while keeping the 284B-parameter architecture unchanged. The API version costs $0.14 per million input tokens on cache miss and $0.28 per million output tokens, roughly one-third of the V4-Pro price. The model now natively supports the Responses API format and is optimized for code tasks, making it accessible to startups and developers without large GPU budgets.
