Price history
Only one price point recorded so far.
The staircase chart appears once a price change is detected.
What it excels at
Native audio, video, and document understanding with a ~1M token context window — strong fit for multi-modal RAG and large-document analysis.
The business tradeoff
Output token cost is steep relative to input, and the largest context windows can be slow to fill — chunk large documents where possible.
