Ok signing off Replit for the day Not a perfect day but a good one. Net net, I rebuilt our core pages and they seem to be working better. Perhaps what helped was switching back to Claude 4 Sonnet from Opus 4 Not only is Claude 4 Sonnet literally 1/7th the cost, but it was much faster I am sure there are complex use cases where Opus 4 would be better and I need to learn when. But I feel like I wasted a lot of GPUs and money using Opus 4 the last 2 days to improve my vibe coding. It was also much slower. I’m staying Team Claude 4 Sonnet until I learn better when to spend 7.5x as much as take 2x as long using Opus 4. Honestly maybe I even have this wrong. The LLM nomenclature is super confusing. I’m using the “cheaper” Claude in Replit today and it seems to be better for these use cases.

Vibe Coding Day 9, Yesterday was biggest roller coaster yet. I got out of bed early, excited to get back @Replit ⠕ despite it constantly ignoring code freezes By end of day, we rewrote core pages and made them much better And then -- it deleted our production database.
