What Claude Sonnet 5 is best for
Claude Sonnet 5 is Anthropic's newest fast-frontier model: it runs faster than Opus 4.8 while landing close to it on quality, so you rarely have to trade speed for smarts. In Pervagans you can make it your default, step up to Opus 4.8 only for the very hardest tasks, and ground it on your own documents inside a Space. It shares the same credit pool as every other model and is part of the Max plan.
- Fast frontier-level reasoning
- Everyday work that still needs depth
- Complex coding at speed
- Work in Spaces on your documents
