Struct StreamOptions

Fields

temperature: Option<f64>

max_tokens: Option<u64>

api_key: Option<String>

headers: HashMap<String, String>

thinking_budget: Option<u64>

Extended thinking budget (Anthropic-specific non-adaptive path).

thinking_enabled: Option<bool>

Explicit on/off for extended thinking.

None means provider default: if thinking_budget is set or (for adaptive-thinking models) an effort is set, thinking is enabled. Some(true) forces thinking on; on adaptive-thinking models this triggers the adaptive path even without a budget. Some(false) forces thinking off regardless of the other fields.

thinking_effort: Option<ThinkingEffort>

Effort level for adaptive thinking (Anthropic-specific for now).

thinking_display: Option<ThinkingDisplay>

Controls how thinking content is returned in the response (Anthropic-specific for now). Defaults to Summarized when thinking is enabled on the Anthropic provider.

session_id: Option<String>

Opaque session identifier for provider-side prompt-cache affinity.

Currently used by the OpenAI provider as prompt_cache_key so consecutive turns of the same conversation hit the same cache shard.

cache_retention: Option<CacheRetention>

Prompt-cache retention hint. None defers to the provider default (currently Short, with PI_CACHE_RETENTION=long env override honoured by the OpenAI provider).
