DeepSeek's first experimental multimodal vision model in the V4 family, open-sourced on Hugging Face under the MIT license on August 31, 2026. It adds a vision encoder and aligner on top of the V4-Flash architecture, gaining image understanding while keeping text-only agent performance on par with V4-Flash. On Terminal-Bench 2.1 it scores 83.9 versus Opus 4.8's 85.0, and leads on DeepSWE (59.3 vs 58.0), signalling near-Opus-4.8 multimodal agent capability.

Strengths
- •Keeps text-only agent performance on par with V4-Flash
- •Near Opus 4.8 on Terminal-Bench 2.1 (83.9 vs 85.0)
- •Open weights under MIT license enable local deployment
- •Strong on image understanding, chart analysis, and visual UI agent tasks
Weaknesses
- •Research-stage release not yet deployed by any inference provider
- •Trails Opus 4.8 on harder text tasks like NL2Repo (57.7 vs 69.7)
- •Context window size not disclosed
- •OCR accuracy and complex UI operation still need real-world validation
Use Cases
- •Understanding image-bearing documents, charts, and screenshots
- •Multimodal agent automation that requires visual input
- •Privacy-sensitive inference via local deployment
