DeepSeek-v4-flash-vision-exp
↗
DeepSeek releases a vision-capable model that processes images alongside text in an OpenAI-compatible API format.
Engineers can now integrate image understanding into applications without switching API conventions. The model handles common formats and offers three ingestion methods, but token costs scale with image size. This lowers the barrier to multimodal features in existing OpenAI-based workflows.

The model accepts JPEG, PNG, GIF, and WebP images via base64, external URLs, or pre-uploaded file references.
Image size and detail level affect token usage and request limits, with a 48 MiB body cap for inline data.
API responses follow OpenAI’s Chat Completions structure, allowing drop-in replacement for text-only calls.
THE READ
What the cluster adds up to.
DeepSeek-v4-flash-vision-exp extends the company’s text-only API to handle images. The change is additive: existing OpenAI client code can send images by adding a content block of type image_url or file. This compatibility reduces migration effort for teams already using OpenAI’s format, but it also inherits OpenAI’s token-based billing model, where image tokens are counted alongside text tokens.
Three ingestion paths are offered. Base64 encoding is simplest for local files but counts against a 48 MiB request body limit. External URLs shift the download burden to DeepSeek, with a 32 MiB per-image cap and a 60-second timeout. The Files API lifts the per-image limit to 64 MiB and avoids repeated uploads, making it the only option for large or reused images. Engineers must choose based on image size, reuse frequency, and network constraints.
Image processing is not free. Before inference, images are resized to a token-equivalent of roughly 800×800 pixels, capping token cost at 384 per image. The detail parameter lets callers trade off cost against visual fidelity, but the default auto setting preserves original resolution. Token counts are published alongside text tokens, so cost estimation tools will need updates to account for multimodal inputs.
The API stops working at the edges of its design. Images over 64 MiB or URLs longer than 8192 characters are rejected. Base64-encoded images that push the request body over 48 MiB also fail. There is no support for video, multi-page documents, or non-standard MIME types. Engineers building pipelines must pre-filter or transcode inputs to stay within these limits.
