DeepSeek-v4-flash-vision-exp

The deepseek-flash model accepts JPEG, PNG, GIF, and WebP images, detecting format from content and routing requests through the current Flash model even with the legacy name deepseek-v4-flash-vision-exp. Images may be provided as base64 data URLs, external URLs (≤32 MiB, ≤8192 characters, 60-second download), or via the Files API using a file_id (≤64 MiB). For image_url inputs, an optional “detail” parameter controls processing depth.
