DeepSeek V4 is a heterogeneous model family where native multimodal capabilities are currently limited to specific variants like V4.1 Flash and the experimental Vision Exp, while others require external vision encoders or reject image inputs entirely. This distinction is critical for developers integrating these models into production pipelines, as sending images to text-only slugs will result in request failures. The guide clarifies which endpoints support native vision processing versus those requiring a separate vision model front-end.

Does DeepSeek V4 Have Vision?

OpenRouterSeptember 16, 20267 min read

DeepSeek V4 is a family of models, and only some of them accept images. This guide maps every V4 slug on our catalog to its input modalities, shows how to send an image to the two that read images, and shows how to put a vision model in front of the text-only ones.

DeepSeek V4 is not one model. On our catalog it is a family that includes V4.1 Flash, V4 Pro 0813, V4 Flash 0731, V4 Flash Vision Exp, two older 0423 checkpoints, and a Flash “latest” alias. The names tell you the tier and the release. They do not tell you which ones accept an image. This guide goes through the family one model at a time, with the exact slugs from our catalog, and shows two ways to use V4 on an image. The first sends the image to a V4 model that reads images. The second runs a separate vision model in front of a text-only V4 model. Two V4 models accept images. DeepSeek V4.1 Flash reads images natively and is the model to use…
