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"

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 see a bit of reuse of words in other various llm related projects.
Langchain/langfuse/langflow
Llama/ollama/llamaindex
so I hadn't been too worried about it when became aware of them.
That's what Show HN is for, getting feedback, and a name changed now would be easy before I post it around more.
And this framework kinda does fall within that space
