Support latest gpt, anthropic and gemini models please

The new models have been out for a bit! Would be great to get support on them!

is this package abandoned? it was so useful, i can’t believe we’re the only ones needing prices for the new models. Or is everybody using a different solution?

Maybe we can open a PR with these new models to help move this issue foward. I'm having the same issue
