DeepSeek Vision: Does V4 Support Image Input?
DeepSeek V4 is text-only in the public API today. The Visual Primitives report shows DeepSeek's vision research, but not a generally available vision endpoint.
Status verified 2026-07-14: the public DeepSeek V4 API is still text-only. This page is kept current as the DeepSeek vision situation changes.
Direct answer: public DeepSeek V4 is text-only today
DeepSeek V4 Pro and V4 Flash do not currently expose image input through the public DeepSeek API. The official model and pricing documentation lists text-generation features such as thinking modes, JSON output, tool calls, prefix completion, and FIM completion, but it does not document an image request format or a public vision model ID.
DeepSeek's own GitHub Copilot integration guide makes the boundary explicit: V4 is text-only, and screenshot support in that extension works by sending the image to another installed vision model before forwarding a text description to DeepSeek. That is a proxy workflow, not native V4 image understanding.
What DeepSeek actually released
On April 30, 2026, DeepSeek published the Thinking with Visual Primitives technical report and its official research repository. The release describes a multimodal research model and promises future publication of internal benchmarks, part of the cold-start dataset, and eventual integration of the model weights into a foundation model.
That wording matters. The official release establishes a real DeepSeek vision research direction, but it does not announce a generally available API endpoint, public product rollout, or downloadable production model. A research report and a public image API are different release milestones.
How visual primitives work
The report argues that stronger image encoders do not solve every visual reasoning failure. A model can perceive objects yet still lose track of which exact object, path, or location its language refers to. DeepSeek calls this the Reference Gap.
The proposed system adds two spatial markers to the reasoning path:
- Points identify locations, paths, and topological relationships.
- Bounding boxes identify objects together with position and scale.
Instead of producing coordinates only as a final detection result, the model can interleave those markers with its reasoning. The goal is to keep multi-step answers anchored to the image while counting objects, tracing a maze, reading a diagram, or referring to a precise region.
The research stack uses DeepSeek V4 Flash as its language-model foundation together with an in-house DeepSeek-ViT encoder. The report also describes aggressive visual-token and KV-cache compression, but those research details do not change the current public API contract.
Current availability at a glance
- DeepSeek V4 text API: available as V4 Pro and V4 Flash.
- Thinking with Visual Primitives report: publicly available from DeepSeek.
- Native V4 image input in the public API: not documented or generally available.
- Public Visual Primitives model weights: described by the release as future work.
- Image handling through a third-party tool: possible when that tool uses a separate vision model or proxy.
This status does not mean DeepSeek lacks vision research. It means developers should not turn a research repository into a product claim before DeepSeek publishes the model, request schema, pricing, and support boundary.
What developers should do now
Do not send image blocks to V4 Pro or V4 Flash based only on the paper, and do not invent model names such as deepseek-v4-vision. Code against the model IDs and input fields listed in the official API documentation.
If an application needs screenshots or document images today, use a separately documented vision model or an explicit proxy pipeline. Keep the boundary visible in logs and UI so users know whether DeepSeek processed the original image or only a generated text description.
For teams tracking the research, the next meaningful launch signals are an official model card or API model ID, a documented image request schema, public weights, image-token pricing, and an update to the supported-feature table. Until one of those appears, DeepSeek Vision is a research direction rather than a public V4 endpoint.

Frequently asked
Does DeepSeek V4 support image input?
Yes, through the experimental deepseek-v4-flash-vision-exp model released on August 21, 2026. The standard V4 Flash and V4 Pro model IDs remain separate from this experimental vision model.
How can I send images to DeepSeek then?
Use deepseek-v4-flash-vision-exp and send mixed image and text input. DeepSeek supports inline base64 images, external image URLs, and Files API references across Chat Completions, Messages, and Responses.
Will DeepSeek release a vision API?
DeepSeek now offers an experimental vision API through V4 Flash Vision Exp. The company has not said whether or when this capability will be folded into the standard V4 Flash or V4 Pro model IDs.
