Initially it had some real problems. large context window-- but you can only paste 4k tokens into the UI, for example. It never seemed like anyone at Google was using it. NotebookLM is a great interface, though, with some nice bells and whistles, and finally shows what Gemini is capable of. However, Opus still has the best long context retrieval with the least hallucination from what I've tried.

3.5 Sonnet is fast, and that is very meaningful to iteration speed, but I find for the level of complexity I throw at it, it strings together really bad solutions compared to the more wholistic solutions I can work through with Opus. I use Sonnet for general knowledge and small questions because it seems to do very well with shorter problems and is more up-to-date on libraries.
