the most frustrating one is sometimes the model will claim it can't do something and the fix for that is to respond "yes you can, and it'll just go and do the thing it just said it can't do. that's what ever come up with technology? a practice to practice really basics social engineering techniques?
Try the dolphin family of models. Dolphin-mixtral is really good, dolphin-llama3 is fine especially in its 8b flavor (I like dolphin-mixtral 8x7b better than dolphin-llama3:70b although the latter is smaller and does run on smaller machines better).
Pretty much the more guardrails there are the more useless it is, and yes, it’s very obviously only done because the lawyers get itchy handing people a digital library with the anarchists cookbook in it.
