Price history
List price per 1M tokens since we started tracking in Jul 2026. The lines are flat because the price hasn't changed since then.
What it excels at
Handles 1M-token contexts and 128k-token outputs for long-document analysis and extended multimodal generation.
The business tradeoff
Output pricing of $30 per million tokens raises costs for high-volume or lengthy responses; large contexts increase latency.
Cheaper from OpenAI
