With xAI, OpenAI, Anthropic's models updating regularly, do I have to keep changing the 'model'=>'gpt-4-1-fast-non-reasoning' name for example in my code on ALL my sites for the next 100 years? Or can I just say 'model'=> use best or something? And no I don't wanna use OpenRouter, I just wanna use whatever is the best but affordable model There's so many places in my code on so many of my sites where I have to change this and they do deprecate models regularly so it's like breaking changes
