Service and inputs
The response returns the completed image synchronously. The service supports prompt reasoning, search enhancement and retained editing context. Returned image links expire after twelve hours. Store required outputs rather than relying on those temporary URLs.Tencent Hy image generation API guide
Practical use
Practical guidance. Review each edit against the previous image and the complete instruction history. Check whether added references change an identity or object that should remain fixed. Save the response history needed for subsequent turns.
