Supported capabilities

Function Calling
Function calling (also known as tool calling) provides a powerful and flexible way for models to interface with external systems and access data outside their training data.
Parallel Function Calling
The model may choose to call multiple functions in a single turn.
Tool Choice
By default the model will determine when and how many tools to use. You can force specific behavior with the tool_choice parameter.
Structured Outputs
Ensures the model will always generate responses that adhere to your supplied JSON Schema.
Streaming
Lets you start printing or processing the beginning of the model's output while it continues generating the full response.
System Messages
You can guide the behavior of the model with system instructions.
Prompt Caching
Optimizes API usage by allowing resuming from specific prefixes in your prompts. This significantly reduces processing time and costs for repetitive tasks or prompts with consistent elements.
