descriptionOverview

Overview

Released on September 10, 2026, DeepSeek V4.1 Flash uses official API model ID deepseek-flash and supports native visual understanding for image-text analysis, coding assistance and general Q&A.

Migration

The release announcement retires V4 Flash and Vision Exp and temporarily routes their compatibility IDs to V4.1 Flash. The announcement and pricing page conflict on Pro routing, so they do not establish the current backing version of the old Pro alias. Use deepseek-flash for this model. No independently unverified prices are recorded here.
