I can not rely on Opus 5.5+ to "fix" whatever crops up. Claude is great but should it find a security related bug one too many times, it gets the Anthropic Shock Collar [cyber]! and I have to pick Opus 4.8 or older to continue and they try to up-sell Mythos which I am not permitted to use without going through their verification program that they will not offer to me. Thankfully for most of my hobby tasks (thats all I do now) Opus 4.8 is usually mostly good enough. In my opinion their newer models are powerful but not something I can rely on. Maybe I am one of the few running into this.
