What it excels at
Processes contexts exceeding one million tokens and generates outputs up to 128k tokens. Supports combined text and vision inputs for complex multimodal tasks.
The business tradeoff
Output pricing at $90 per million tokens raises expenses for lengthy responses. Batch designation may introduce higher latency than standard API endpoints.
