It's not dramatic, it's just something you personally haven't noticed. A quick search regarding Gemini weather hallucination shows it's both widespread and something not mitigated by recent model releases. It makes up other basic information or can't perform tasks that a simple assistant can do properly (e.g. mixing up calendar events, emails, can't navigate etc). Why defend what is clearly a move to increase a department's KPIs when you as a consumer receive less in return?

Gemini defaults to performing search from within its own weights until you curse it and damn it sufficiently to do basic RAG. Utter trash on this limitation/behavior alone but there are so many other hallucinatory shenanigans it embraces so why limit yourself to one.

Compare and contrast with asking Claude or ChatGPT a question directly and get back to me.

I never thought I'd see a Gemini apologist.
