​
Best for

  • Hardest reasoning, mathematical proofs, programming competitions
  • Long-context analysis (full books, large codebases, extensive logs)
  • Research workloads where you’d reach for a frontier closed-model API

On context cost

The full 1M context is included in the standard token rate — no per-token surcharge for using the long window. Pair with context caching and the economics on RAG workloads get very compelling.
