Thanks for the notes, I thought it would be a more detailed prompt :) Any reason why you choose Opus instead of other LLMs, was it because of the 200k context window?
I'm defaulting to Opus at the moment partly because it's brand new and so I need to spend time with it to get a feel for it - but also because so far it seems to be better than GPT-4 for code stuff. I've had a bunch of examples of it writing mistake-free code that GPT-4 had generated with small bugs in.
