I was surprised when I learned about the Greek derivation. In the UK it's slang for common sense ("use your nous, mate"). I have to wonder how a bit of Ancient Greek ended up as UK slang.
Probably less common today but honestly I'd be surprised if someone didn't know it at all. Try asking someone over fifty in England what "use your nous" means.
A quick dip into Google Books throws back this from the works of George Garrett, a Liverpool-born working class writer who wrote about being a merchant seaman during World War I: "An older fireman stopped them. 'Use your nous,' he sang out. 'You can't pile into another room and waken all hands for the sake of an individual."
Or this from The Spectator in the 80s: "Use your nous, you silly cow"
Actually when I was bouncing ideas off Claude it was suggested with the alternative spelling of noos. Then I can keep the concept and only have have one letter to change
And if it is is by Nous Research we there definitely needs to be clearer branding as this is very confusing.
If OP is not Nous Research (which I suspect to be the case) then a name change is a must as they're already a fairly well established company in the LLM space (surprised OP isn't aware of the name collision already). It's a bit similar to creating a new library with the "Smiling Face with Open Hands emoji"[0] as your logo
I'm not affiliated with Nous Research in anyway, but do work in the LLM space and at least in this community it's a fairly well known org. Since this project also is in that space I was just adding support for parent's observation.
