What this spreadsheet does

- Compare projected cost across two or three models
- Check cost per request at a given volume

Frequently asked questions
Do I need to update pricing manually?
Yes, model pricing changes over time, so per-model rates are entered as editable inputs rather than hardcoded.
Can I compare more than one model?
Yes, the Model Comparison tab is built to compare projected cost across multiple models at the same volume.
