Hello, I experienced severe hallucination and false answer from Gemini pro GA model, I can’t share file that contains long story required for analysis. but I can basically describe this model doing poor understanding on a story, provide false content from chapter summary, neglect important information and plot point, hallucinate non-existence context, and trying to misguide user with its [correct answer]. I flag all its error and it apologize and make mistake over and over again!
