DeepSeek-V4-Flash-Vision-Exp
The only DeepSeek model that takes images — use it for screenshot-driven and chart/document-reading agents at identical Flash pricing; it is explicitly experimental and drops FIM completion, so keep text-only traffic on deepseek-v4-flash. Images bill as input tokens (up to 384 tokens each), accepted as base64, public URL (max 32 MiB), or Files API file_id (max 64 MiB, upload is free).

What it is for
Images bill as input tokens (up to 384 tokens each), accepted as base64, public URL (max 32 MiB), or Files API file_id (max 64 MiB, upload is free).
At a three-to-one input-to-output ratio, DeepSeek-V4-Flash-Vision-Exp costs $0.66 per million tokens blended. A workload of one million input and 330,000 output tokens per day would run about $26.27 per month at list price, before caching or batch discounts.
Cost at list price
