What breaks when you switch Published provider documentation
Moving from OpenAI to Qwen, 3 of the 5 features may not carry over, by each provider’s documentation:
- Strict JSON schemas — OpenAI: yes; Qwen: partly. Code that parses answers without checks starts failing where a provider promises only valid JSON, not your schema.
- Streamed tool arguments — OpenAI: yes; Qwen: not stated. An interface that shows arguments as they are written sees nothing until the whole call is ready.
- Cache covers tool definitions — OpenAI: yes; Qwen: not stated. Where the cache does not cover tool definitions, a long tool list is paid as fresh input on every request.
Moving from Qwen to OpenAI: every feature that Qwen’s documentation lists as supported is also listed as supported by OpenAI.
| Feature of the API | OpenAI | Qwen |
|---|---|---|
| Strict JSON schemas | Yes | Partly |
| Parallel tool calls | Yes | Yes |
| Streamed tool arguments | Yes | Not stated |
| Reasoning with tools | Yes | Yes |
| Cache covers tool definitions | Yes | Not stated |
