The Zhipu 4V adaptor now supports the OpenAI Responses relay mode. It builds the /api/v1/responses endpoint URL and passes Responses requests through unchanged.

Poem

A rabbit hops where Responses flow
The Zhipu path now knows where to go
Requests pass through, unchanged and bright
The endpoint points to the proper site
Ears up, the relay works just right
