Fields

temperature: Option<f64>

Sampling temperature (0.0 to 2.0)

max_tokens: Option<usize>

Maximum tokens to generate

api_key: Option<String>

API key (overrides environment variable) This field is excluded from serialization and Debug output to prevent leakage.

Cache retention preference

session_id: Option<String>

Session ID for providers that support session-based caching

headers: HashMap<String, String>

Custom HTTP headers to include

thinking_level: Option<ThinkingLevel>

Thinking/reasoning level

thinking_budgets: Option<ThinkingBudgets>

Custom token budgets for thinking levels
