Price history

List price per 1M tokens since we started tracking in Jun 2026. The lines are flat because the price hasn't changed since then.

What it excels at

Processes 1M-token context with vision at the lowest OpenAI price point, enabling high-volume classification, extraction, and simple multimodal workflows.

The business tradeoff

Reasoning depth and complex instruction following are materially weaker than GPT-4o or o-series models; output quality drops quickly on multi-step tasks.
