Chat（tool invocation）

POST

/chat/completions

The 302 platform has added tool invocation capabilities (commonly known as Function Call) to all models.
The principle is that if the model itself does not support tool invocation, you only need to pass in the tools parameter. The 302 backend will automatically parse the parameters, convert them into prompts for the model, and transform the model output into the tool_call format.

Price: No change in the cost of existing models
