"""Client for the non-chat inference endpoints (responses, messages, rerank,
|
|
embeddings, audio speech, image generation).
|
|
|
|
Each test registers the deployment it needs through /model/new (deleted on
|
|
teardown), so nothing is hardcoded into the gateway config, then drives the
|
|
endpoint with `send` and parses the provider-native body with a suite-local model
|
|
so the assertion is on real content, not just a 200.
