My experience with Gemini 3.8 Flash has been awful; it gives me the most hallucinations out of the major models. I'm not using it for coding, but general research on different topics.
The web version of Gemini is awful at search but I don't think that's the models fault.
I'm also not using it for coding but I've found Flash 3.8 to generate much better HTML output than Sonnet or Opus.
