Price history
Only one price point recorded so far.
The staircase chart appears once a price change is detected.
What it excels at
Performs well on long-context code generation, editing, and repository-scale analysis. Supports vision inputs for multimodal code and documentation tasks.
The business tradeoff
Batch-only access increases latency and precludes interactive use. Output token pricing is elevated relative to input, raising costs for code-heavy workloads.
