Multi Model Cost Calculations are Bugged #7387
Description
Description
I think i found a bug with cost calculation. Occasionally i will use multiple models (generally claude to do an plan and initial implementation, and gemini to cleanup). I noticed today the cost calculation actually went down after i started using gemini. I think maybe its not taking into account what model each message was sent to ?

This issue might be a duplicate of existing issues. Please check:
These issues all relate to cost calculation inaccuracies. Your case specifically mentions costs decreasing after switching models, which shares similarities with the cost tracking problems described in these issues.
Feel free to ignore if none of these address your specific case.

Got claude to do an analysis. It seems like a bug with TUI showing information for the last 100 messages, when the session is longer.

I'm looking at this issue too. It seems that #7763 needs to be merged first before we can work on anything else.
