Description

When attempting to call the @cf/openai/gpt-oss-120b model through the Workers AI provider, the API returns a validation error indicating that neither input nor requests is being matched. This happens even when following the official documentation for text generation.

It appears the request schema for this model may differ from other OpenAI-compatible endpoints or isn’t aligned with the documented usage.
