API access is not confirmed here
This model is not listed in the catalog retrieved for this page. A developer announcement or provider preview does not confirm access through API Stock. An integration date and request price have not been published here.
What the sources establish
DeepSeek's official changelog records V4.1 Flash and its October 17 update. It says the deepseek-flash alias serves the updated vendor model. A vendor alias update must not be assumed to update every third-party route.
