Price history
List price per 1M tokens since we started tracking in Aug 2026. Each step marks a price change — hover a point for the exact date and rate.
What it excels at
Handles 1M-token contexts with 128k output for long-document or multi-modal analysis. Strong on complex reasoning tasks requiring sustained coherence across large inputs.
The business tradeoff
Output pricing at $15/M tokens raises costs for generation-heavy use. Batch designation implies higher latency unsuitable for interactive applications.
