What makes Claude Sonnet 5 different

Sonnet 5 is the everyday Anthropic model: strong enough for serious coding and writing without the flagship Opus tradeoff. It is the first Claude model to try for most briefs. Choose Opus 5 for unusually difficult reasoning, and Haiku when throughput and short response time matter more than depth.

What Claude Sonnet 5 is best for

  • High-quality writing, editing and content work
  • Coding: generation, review, refactoring and explanation
  • Summarising and questioning long documents
  • Structured analysis and report generation
  • Everyday tasks that still deserve a top-tier model

How to use Claude Sonnet 5

Step 2 For code, paste the relevant files and ask for the change plus an explanation of what it improved; Sonnet 5 handles multi-file reasoning well.
Step 3 Use follow-ups to tighten drafts, restructure into sections or tables, or adapt the same content for a different reader.
