The staircase chart appears once a price change is detected.
What it excels at
Strong results on reasoning, math, and coding benchmarks. Supports large context and output windows at low per-token cost.
The business tradeoff
Batch API adds latency and removes real-time streaming. Mini size shows occasional gaps versus full-scale o-series models on complex multi-step tasks.
