About this model
DeepSeek V4 Flash 0731 is the official release of DeepSeek V4 Flash, superseding the preview version. It is a 304B-parameter Mixture-of-Experts model (256 routed experts plus one shared expert, 6 active per token) with an attached DSpark speculative-decoding module and a 1M-token context window. Deliberation is controlled through three reasoning effort levels — low, high and max — with up to 384K output tokens recommended at the high and max levels. On published agentic benchmarks it reaches 82.7 on Terminal Bench 2.1, 70.3 on Toolathlon-Verified and 54.4 on DeepSWE, outperforming DeepSeek V4 Pro (Preview) despite a far smaller activated parameter count. Text-only, with function calling and structured output, released under the MIT License.
