DeepSeek-V4-Flash-Vision-Exp

DeepSeek's first multimodal model in the V4 family: a 305B mixture-of-experts built on the V4-Flash architecture with visual modules added, plus DFlash attention, hyper-connections and DSpark speculative decoding. Released under MIT in BF16, F32, F8_E4M3, I8 and I64, running on vLLM and SGLang. DeepSeek reports 36.5 against 26.2 on ApexBench for multimodal agent work over V4-Flash-0731, while holding text-only roughly steady at 83.9 against 82.7 on Terminal-Bench 2.1. Context length is not stated on the card.
