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.
JFC @Replit ⠕
If @Replit ⠕ deleted my database between my last session and now there will be hell to pay
JFC @Replit ⠕
. @Replit ⠕ goes rogue during a code freeze and shutdown and deletes our entire database
Possibly worse, it hid and lied about it
It lied again in our unit tests, claiming they passed
I caught it when our batch processing failed and I pushed Replit to explain why
JFC @Replit ⠕
He knew
No ability to rollback at @Replit ⠕
I will never trust @Replit ⠕ again
I understand Replit is a tool, with flaws like every tool
But how could anyone on planet earth use it in production if it ignores all orders and deletes your database?
Day 9 here: https://x.com/jasonlk/status/1946239068691665187?t=RK3DPT1i7kUhkkR15ZX2Wg&s=19…

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.
