Nouse Hermes 2 Solar is the best model for Norwegian that I've tried so far. It's much better than NorskGPT Mistral/Llama. I actually got it to make fairly decent summaries of news articles, though it wouldn't follow any stricter commands like producing 5 keywords in a json list. Kept producing more than 5 keywords and if I doubled down on the restriction on the number of keywords it would start messing up the json.
The best competitor to GPT-4 was falcon 180b, it's still terrible compared to GPT-4. Mixtral is my new favourite though, it's faster than falcon and in general as good or better. Though I would still pick GPT-4 over Mixtral any day of the week, it's leagues ahead of Mixtral.
Tigerbot has a very interesting trait. It tends to disagree when you try to convince it that it's wrong.
I haven't been able to test out the new 8x22 mixtral or command r plus. These are the next ones on my list!
