# DeepSeek launches DeepSeek-V4-Flash-Vision-Exp and Files API

The multimodal model is available via the API with images tokenized and billed at up to 384 tokens each under V4-Flash pricing.

- Images can be supplied using base64, external URLs, or the new free Files API.
- The Files API allows users to upload an image once and reuse it across multiple requests using a file_id.
- DeepSeek Harness 0.1.1 includes out-of-the-box support for the model.
- The model supports Chat Completions, Messages, and Responses endpoints with mixed text and image inputs.

## Why it matters

Developers using DeepSeek's API can now run visual agent workflows and reduce bandwidth overhead by referencing uploaded image files directly.
