Claude Opus 4.6 Quirks & Gotchas

  • Best for long-context document analysis and legal review
  • Tool calling requires structured prompt — prone to verbose refusal without explicit output schema

o1 Quirks & Gotchas

  • Reasoning model — high latency by design, not for real-time use
  • Best for complex math/code reasoning where accuracy > speed
  • Use o3-mini when you need reasoning with lower latency
