Claude Sonnet 4.6
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.
Can still misstep on the hardest multi-step reasoning chains where Opus would succeed — budget for occasional escalation to a flagship model.
GPT-5.4 Nano
Cheapest OpenAI option for high-throughput classification, tagging, and routing — ideal as a first-pass filter before a stronger model.
Limited reasoning depth means it should be treated as a triage layer, not a final answer source, for anything business-critical.
