Price history
Only one price point recorded so far.
The staircase chart appears once a price change is detected.
What it excels at
Handles 256k-token context and output windows for long-document or repository-scale tasks. Low input pricing supports high-volume ingestion workloads.
The business tradeoff
Open-weights deployment introduces hosting variance and operational overhead. Output-token pricing is elevated relative to input; ecosystem tooling remains narrower than major providers.
