This begs the question: how Good is it? Did anyone test it yet?

[–] hylaea@reddthat.com 2 points 1 month ago (4 children)

well i tested it and wasn't impressed. my prompts were about Python3, that i'm working on a script and if i could show the AI my code so we can work together on it. It didn't wait for my input, just gave me an endless python tutorial. I said wait till i show you my code but nope...

8b and 70b nets https://huggingface.co/collections/swiss-ai/apertus-llm-68b699e65415c231ace3b059

From 8b I wouldn’t expect much besides basic language skills, but 70b might be better than ChatGPT 3.5
