Description
DeepSeek-V4-Flash-0731 is the latest release in the DeepSeek series, designed to enhance agentic capabilities significantly. This model supersedes the preview version, DeepSeek-V4-Flash, by incorporating a speculative decoding module similar to DeepSeek-V4-Flash-DSpark. Despite having a smaller activated parameter count, DeepSeek-V4-Flash-0731 outperforms its predecessor, DeepSeek-V4-Pro (Preview), across multiple benchmarks.

The model excels in various benchmarks, including Terminal Bench 2.1, NL2Repo, Cybergym, and DeepSWE, demonstrating its competitiveness with leading proprietary models. For instance, it scores 82.7 on Terminal Bench 2.1, surpassing the preview version's 61.8 and DeepSeek-V4-Pro's 72.1. It also shows strong performance in NL2Repo and Cybergym, with scores of 54.2 and 76.7, respectively.
DeepSeek-V4-Flash-0731 supports three levels of reasoning effort—low, high, and max—allowing users to control the deliberation the model undertakes before providing answers. The model is designed for easy deployment with vLLM and SGLang, offering detailed instructions for local deployment and model weight conversion.
The model is licensed under the MIT License, ensuring open access to its capabilities. Users can explore its functionalities through a dedicated encoding folder that provides Python scripts and test cases for encoding messages in an OpenAI-compatible format. This release does not include a Jinja-format chat template but offers comprehensive documentation for message encoding and output parsing.
