@fraser.ai: Stop switching models in Claude Code👇 Everyone tells you to use Opus for the hard stuff and Sonnet for the legwork. In a lot of cases that advice is costing you money. Claude Code doesn't remember anything between prompts. Every turn it resends your whole context, and the only reason you're not paying for all of it every time is the cache. Switching models wipes that cache. So every time you flip between Opus and Sonnet mid-session, your next turn gets billed for the entire context window again. Do your planning first, switch model once, then run your tasks. Stop bouncing between models and watch your usage drop. Follow for more Claude Code sauce. #ClaudeCode #Claude #AITools #AIforBusiness
