Show pricing for prompt

[slavos1]

I use llm often and like llm prompt -u flag.
What would be cool is to see the cumulative price for input+output tokens when llm finishes.

For now, I just copy&paste to the helpful https://tools.simonwillison.net/llm-prices calculator but it's a bit clunky ... since llm knows the model I used, the number of input+output tokens, it can show me the total price?

I could not find a llm plugin for that. Even hard-coded prices in such a plugin would be useful.

Thanks for consideration!
