Price history

Only one price point recorded so far.

The staircase chart appears once a price change is detected.

What it excels at

Large 256k context window and low per-token cost support high-volume long-document and multi-image workloads. Open weights enable on-premise deployment and fine-tuning.

The business tradeoff

Limited ecosystem and unknown real-world reasoning consistency relative to established providers. Output-token pricing remains higher than input, affecting long-generation economics.
