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.
