The big idea
Claude 4 is Anthropic's flagship line. Opus 4 is the heavyweight for coding and long reasoning; Sonnet 4 is the daily driver — fast, cheap, smart. There's a 1M-token version for massive context.
Some examples
- Use Opus 4 for serious coding sessions and long documents.
- Use Sonnet 4 for daily tasks — it's cheap and almost as smart.
- Claude 4 leads SWE-Bench (real coding) leaderboards.
- 1M context lets you paste a whole book in one prompt.
Try it!
Run the same coding question on Sonnet 4 and Opus 4. Compare quality. Notice when Opus is worth it.
