Universal LLM response structure

Fields

content: Option<String>

The response content text

tool_calls: Option<Vec<ToolCall>>

Tool calls made by the model

model: String

The model that generated this response

usage: Option<Usage>

Token usage statistics

finish_reason: FinishReason

Why the response finished

reasoning: Option<String>

Reasoning content (for models that support it)

reasoning_details: Option<Vec<String>>

Detailed reasoning traces (for models that support it)

tool_references: Vec<String>

Tool references for context

request_id: Option<String>

Request ID from the provider

organization_id: Option<String>

Organization ID from the provider

compaction: Option<String>

Compaction summary content from Anthropic’s server-side compaction. Populated when stop_reason is Pause (from "compaction"). The caller should pass this back in subsequent requests so the API can drop prior messages before the compaction block.
