Gemini is terrible. It's way worse than even GPT 3. Never mind 3.5 or Claude. It's basically useless. Even the simplest things like trivial code transformations don't work. Gemini goes rogue all the time and starts to do things it shouldn't.
I get the feeling that in desperation people at Google are hacking the metrics to make their model look good. While in reality it's just junk.
No model, and I've tried a lot of them, has such a massive gap between good benchmark performance and horrible real world performance.
