Unsloth Dynamic 2.0 achieves superior accuracy & outperforms other leading quants.
- To run DeepSeek-V4-Flash-0731 in full precision lossless, run Q8 (UD-Q8_K_XL), which is 162GB and only 7GB bigger than Q4 (UD-Q4_K_XL).
- See our DeepSeek-V4 guide for quantization analysis and instructions.
- You can now run DeepSeek-V4-Flash-0731 in Unsloth Studio with toggles for High and Max thinking.
- New DSpark support allowing up to 2x faster decoding! Docs for DSpark
DeepSeek-V4-Flash-0731
Technical Report👁️
Introduction
DeepSeek-V4-Flash-0731 is the official release of DeepSeek-V4-Flash, superseding the preview version, with substantially enhanced agentic capabilities. It has the same model structure as DeepSeek-V4-Flash-DSpark, i.e. it comes with a speculative decoding module attached.
DeepSeek-V4-Flash-0731 outperforms DeepSeek-V4-Pro (Preview) on benchmarks listed below despite its far smaller activated parameter count, and is broadly competitive with the strongest proprietary models available.
Notes:
- For the Code Agent tasks among the public benchmarks above, DeepSeek-V4-Flash-0731 is evaluated with the minimal mode of DeepSeek Harness (to be released) as the agent framework, using the
max reasoning effort level with temperature = 1.0, top_p = 0.95.
- † DSBench-FullStack is an internal full-stack development test set; DSBench-Hard is an internal test set of difficult coding-agent problems.
