Select the exact model and variant

Check the complete Flash or Pro version and route ID. Dated, regional and Fast variants can carry different capabilities or prices; a name alone is not evidence of equivalent output or lower latency.

Store a dedicated key in your environment and follow the authentication quickstart. Use the exact ID above; a paid model ID and a :free alias have separate funding rules. See the eligible free aliases and shared monthly pool before assuming a free version is available.

Calculate ordinary input, cache and output costs, compare gateway tradeoffs, or read why your token ratio matters. Client-specific streaming and tool behavior must be tested separately; see agent compatibility.
