Corrected: DeepSeek-V4.1-Flash: Smarter, Faster, More Efficient

DeepSeekNew modelConfirmed

Correction: Updated on 4 Oct: the summary no longer says V4.1-Flash handles screenshots and charts. DeepSeek's post says only native visual understanding and multimodal API support. The earlier V4-Pro correction still applies.

DeepSeek V4.1-Flash has native visual understanding as well as text, and its API supports multimodal input.

Developers using the older V4-Flash model names temporarily get the new model instead.

Who can use it: Available on the DeepSeek API as deepseek-flash. Regional or account restrictions are not specified by the source.
When: New pricing began September 10 at 04:00 UTC. The release post said V4-Pro API requests would route to V4.1-Flash from September 14 at 04:00 UTC, but DeepSeek's change log now says V4-Pro API service continues after September 14 with billing unchanged.
