Seriously, what just happened to the weekly quota on 20x? : r/ClaudeCode
GPT-5.6 Sol just deleted my whole production database. That's it. Not a joke. This had never happened to me before, with any other model, ever. It's not safe.
Some thoughts about GPT-5.6-Sol after ~30B tokens:
‼️ BREAKING: xAI's Grok Build CLI was uploading entire Git repositories to a Google Cloud bucket, private codebases and unredacted secrets included. The uploads quietly stopped via a hidden server-side flag, and xAI still has not said a word about scope, retention, or deletion.

Code written by GPT 5.6 Sol canceled EVERY active Stripe subscription my business had. In 7 seconds. While I slept. Fable 5 has never done this to me. https://t.co/1FAhZ7JoJc" / X
