Price history
Only one price point recorded so far.
The staircase chart appears once a price change is detected.
What it excels at
Supports 1M-token context and 128k output at low input cost; open weights allow fine-tuning and self-hosting.
The business tradeoff
Unknown provider yields immature ecosystem and tooling; output pricing and inference latency depend entirely on user-chosen hosting.
