What Should Happen?

[BUG] Sonnet 4.6 1M and Opus 4.8 are so fucked up that they keep hallucinating and tcannot think like a principal engineer and actually solving the issues. I spent 9 days for many hours trying to fix a chat interface and these shits keep hallucinating despite strict rules. I wasted 500$ so far and multiple hours including late nights and still no solutions. I hope you Anthropic and all the AI companies fail miserably
