Claude Claude Code OAuth (Anthropic /v1/messages + oauth-2025-04-20)

The gold standard for coding agents.

Anthropic's Claude family is the reference point everyone else gets compared against. Sonnet 4.6 and Opus 4.7 routinely top SWE-Bench Verified, and instruction-following on long contexts is notably tighter than the alternatives. We benchmark via the Claude Code subscription that ships with Claude Pro / Max — flat monthly fee, no per-token surprises.

Strengths

  • Best-in-class coding (Claude 4.7 leads SWE-Bench Verified at 87.6%)
  • Long-context, careful instruction-following
  • Flat subscription: no per-token surprises

When to use it

  • Coding, long-document analysis, careful refactors
  • When instruction-following accuracy matters
  • If you already pay for Claude Pro/Max, reuse the quota from the CLI
