✅ Core Strengths & Ideal Workloads

  • Top-tier empirical capability score (93 index)
  • Supports 1M context window and prompt caching ($0.25/M read)

⚠️ Limitations & Practical Caveats

  • Strict regional and payment controls on direct API accounts; use AWS Bedrock, Google Vertex AI, or OpenRouter for reliable global access.
  • Extended thinking generates internal reasoning tokens (~1.8x output multiplier)
  • Premium token pricing; route simpler turns to lighter Flash/Haiku/Luna models
