Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

native_finish_reason: Option<String>

The upstream provider’s own finish reason. Chat only.

service_tier: Option<String>

cost: Option<f64>

The request’s cost in credits. Both routes.

cost_details: Option<Map<String, Value>>
