DeepSeek released V4-Flash-0731, a 304-billion-parameter model with enhanced agentic capabilities that ranks above larger competitors in performance benchmarks. The model costs $0.14 per million input tokens and $0.27 per million output tokens, positioning it as potentially the best value-for-intelligence option currently available. Users can access improved outputs by adjusting the reasoning effort setting to high on supported platforms like OpenRouter.

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.
