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 Mini
Good default for everyday chat, summarization, and lightweight agent steps where GPT-5.4-level reasoning isn't required.
Quality gap widens on long, multi-hop reasoning tasks — needs careful prompt design to avoid silent failures on edge cases.
