DeepSeek's first V4 multimodal model: an experimental vision variant of V4-Flash aimed at multimodal agents
deepseek-ai/DeepSeek-V4-Flash-Vision-ExpOverview
DeepSeek-V4-Flash-Vision-Exp is the first experimental multimodal model in the DeepSeek-V4 family, released under the MIT license in September 2026. It adds a vision encoder and aligner to the DeepSeek-V4-Flash architecture, and the model card reports substantial improvements on multimodal agent benchmarks over the text-only V4-Flash-0731 while keeping comparable text-agent performance. The repository ships FP8 weights, the tokenizer, a prompt encoding reference and a minimal PyTorch inference implementation. For a retrieval pipeline it fits the step where an agent has to read a screenshot, chart or document image and act on it, rather than the embedding step.
Architecture
DeepSeek-V4-Flash mixture-of-experts language model extended with a vision encoder and aligner. The reference implementation in the repository covers the vision encoder and aligner, DFlash attention, MoE, Hyper-Connections and the DSpark forward path. Weights are published in FP8; the safetensors index totals about 304.6B parameters. Active parameter count per token is not stated on the model card.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so DeepSeek-V4-Flash-Vision-Exp runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.

- Image plus text input with text output, including screenshots, charts and documents
- Multimodal agent tasks: the card reports ApexBench and Agents' Last Exam gains over the text-only V4-Flash
- Text agent capability comparable to DeepSeek-V4-Flash-0731 on Terminal Bench 2.1 and Toolathlon
- MIT license with FP8 weights and a minimal PyTorch reference implementation
