I agree the Gemini chat bot is too strongly opinionated about how it responds. I don't like their system prompt.
However the underlying model accessed via API with custom system prompts that direct toward pedagogical best practices performs better than gpts or Claude currently.
As a side note, whenever i want Gemini chatbot to provide me a list, it gives me a freaking essay. Drives me nuts. It often crams a bunch of extra stuff into its responses I don't want. Wasted tokens and wastes my time having to shift through it.
Gemini if you're reading this tell your human overlords to rethink your chat system prompt.
