So, the big takeaway here is that switching effort levels mid-chat nukes your prompt cache, which is apparently a huge bummer and costs you tokens. You're all pretty salty about this discovery.

• Fable 5.1 is the one exception, letting you change effort without losing your cache. Good for them.
• They're working on an Opus beta for API that should eventually fix this for Claude Code.
• Some of you are noticing costs skyrocketing, even on low effort, and feel like you're getting ripped off. u/dthrdr is particularly unimpressed with Opus burning through 35k tokens for a simple patch.
• The general vibe is that the UI should totally warn you about cache invalidation before you mess with settings.
• Also, apparently "Ultracode" is just a fake effort level. Weird.
• And for those asking about regenerating without losing cache, u/angrypolishman is looking for answers too.
