Definitely one of the weaker areas in the current LLM boom. Comparing models, or even different versions of the same model, is a pseudo-scientific mess.
I'm still using https://lmarena.ai/leaderboard. Perhaps there is something better and someone will pipe up to tell me about it. But we use LLMs at work and have unexplainable variations between them.
And when we get a prompt working reliably on one model, we often have trouble porting it to another LLM - even straight "version upgrades" such as from GPT-4 to -5. Your prompt and your model become highly coupled quite easily.
I dunno what to do about it and am tending to just pick Gemini as a result.
