Interface AIChatStreamToolCallDelta

Incremental tool-call data emitted as the model assembles a tool invocation (SSE tool_call_delta event).

interface AIChatStreamToolCallDelta {
    delta?: string;
    id?: string;
    name?: string;
}

Properties

delta?: string

A chunk of the tool call's serialized arguments. Concatenate deltas to reconstruct the arguments JSON.
