Use multiple AI models at once to see where they agree/disagree

LLM comparison

Open

Multiple models reviewing content is so helpful because we can better understand when there's a strong case for X, or divergences about Y, and ultimately get a more full understanding because of that. Great work!

Seems to be working quite well as of today. It was most likely a temporary issue. Give it another go!

I’ve been playing with cogmi for a week and it’s really cool what insights it’s giving me about performance. Usually I don’t even think about when to stop, but now there’s some data to focus on. It’s like keeping tabs on circardian rhythm but for brain performance.
