Use /model to Switch Between Claude Models Mid-Session
Most people pick a model at the start of a session and stick with it the whole way through. That means paying Opus prices for work Sonnet handles just as well.
Type /model to switch at any point mid-session:
/model
This opens an interactive model picker. The real pattern: use Opus when you're planning, reasoning through architecture, or working on hard problems. Switch to Sonnet once you move into execution mode.
Opus is roughly 5x more expensive, and roughly 80% of a typical session is execution: applying changes, running tests, committing files. You don't need maximum reasoning power for that.
Think with Opus. Execute with Sonnet. Same quality output, way more runway on your usage limits.
