Claude Opus 4.5 Quirks & Gotchas

  • Deep analytical reasoning — best for structured problem-solving
  • 200K context is limiting compared to 1M of Opus 4.6+ — upgrade for long-document tasks

Command R+ Quirks & Gotchas

  • Optimized for RAG workflows — best enterprise document search model
  • Tool calling requires explicit step definitions in Cohere's tool-use format
