Which to pick
Pick **Claude Sonnet 4.5** for ninety-plus percent of everyday team chat. At $3 in / $15 out per Mtok it lands well inside the credit pool a Pro org can comfortably budget, and Anthropic's gap between Sonnet and Opus on most general-purpose tasks is small enough that the price multiplier rarely pays off.
Pick **Claude Opus 4.5** when the turn is genuinely hard — multi-step refactors, long-context synthesis across a sprawling repo, dense legal or technical review where you'd accept paying five times more for a noticeably better answer. On Switchy this is gated to Pro+, which keeps Starter visitors from accidentally spending the whole month's credits on one 30-minute Opus session.
