Price history

What it excels at

Strong price-to-performance for production agents: reliable tool use, structured JSON output, and solid coding ability at roughly a fifth of Opus's cost.

The business tradeoff

Can still misstep on the hardest multi-step reasoning chains where Opus would succeed — budget for occasional escalation to a flagship model.
