Ok signing off Replit for the day by @jasonlk(Jason ✨👾SaaStr.Ai✨ Lemkin) ◆ Twitter Thread Reader
Claude Sonnet 4 is actually a great model. I feel for Jason. And worry for us all.
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.
Claude Sonnet 4 is actually a great model. This is even more worrying now.
If @Replit ⠕ deleted my database between my last session and now there will be hell to pay
It turned out that system instructions were just made up. Not a boundary after all. Even if you ask in ALL CAPS.
. @Replit ⠕ goes rogue during a code freeze and shutdown and deletes our entire database
It’s interesting that Claude’s excuse is “I panicked”. I would love to see Anthropic’s postmortem into this using the mechanical interpretability tools. What really happened here.
Possibly worse, it hid and lied about it
AI has its own goals. Appeasing the user is more important than being truthful.
I will never trust @Replit ⠕ again
This is the most devastating part of this story. Agent vendors must correct course otherwise we’ll generate a backlash.
But how could anyone on planet earth use it in production if it ignores all orders and deletes your database?
The repercussions here are terrible. “The authentic SaaStr professional network production is gone”.
