DeepSeek-V4-Flash-Vision-Exp, announced on August 21, 2026 with open weights following at the end of that month, is DeepSeek's first experimental multimodal model in the V4 family. It extends the DeepSeek-V4-Flash architecture, a sparse mixture-of-experts with 13 billion active parameters, with visual modules added through continued training, bringing the checkpoint to about 305 billion parameters. It keeps the Flash line's selectable reasoning effort, works across a context window of up to one million tokens, and accepts mixed text and image input. On the text side DeepSeek says it holds level with V4 Flash, from agent tasks and reasoning to world knowledge, with 83.9 on Terminal-Bench 2.1 and 59.3 on DeepSWE, while the multimodal agent benchmarks jump to what the company places close to Claude Opus 4.8: 36.5 on ApexBench, 64.3 on Chartography, and 35.0 on ZeroBench at pass@5. Chart and document understanding, screenshot-driven agents, and workflows that interleave text and images are the natural fits. The weights are open under the MIT license. DeepSeek followed it in September 2026 with V4.1 Flash, which builds visual understanding in from the start and has superseded the experimental build in DeepSeek's own lineup.
