Claude Sonnet 4.6

Strengths

• +Best-in-class for code refactoring and multi-step pull requests
• +Very stable tool-use loops — low hallucination on arguments
• +64k output tokens fit whole files in one response

Weaknesses

• −Knowledge cutoff July 2025 — no recent web knowledge
• −No native JSON mode — schema enforcement via tool-call trick

Use cases

• →Agentic coding: Claude Code, Cursor Composer, autonomous PR generation
• →Long-context RAG over code repos and document libraries
• →Structured data extraction with complex schemas

Not the right pick for

• ×Realtime chat with sub-200ms latency — use Haiku or Flash
