What routing would give back, on your own bill.
Drop your provider's usage export. The page aggregates your volumes per model, applies the public prices, and shows the exact gap with the cheaper model in the same family. Nothing to install, no key to hand over.
The file is read by your browser and sent nowhere, ours included. That is the whole point: a page that receives nothing has nothing to ask you for, no account and no API key.
CSV or JSON, 20 MB maximum. The file is read in place: no network request is made during the analysis.
The method
What this number contains, and what it does not
Price against price
Your input and output volumes per model, multiplied by the providers' public prices. No estimate, no average borrowed from somebody else's traffic.
A ceiling, not a promise
The calculation assumes all of your traffic is routable. In practice you will route the simple tasks and keep the bigger model elsewhere, so read this number as the upper bound of what is reachable.
Never a guessed price
A model missing from our price table is listed as not priced and enters no total. An empty line beats an invented figure.
Same provider only
The alternative always belongs to the same family. Your key opens one world, and comparing across providers would mean changing key, not model.
Your export
Where to find it, in two minutes
- 01OpenAI: open platform.openai.com/usage, pick the period, then Export to download the CSV.
- 02Anthropic: console.anthropic.com, Usage section, then the CSV export for the period you want.
- 03Column names differ from one export to the next. The reader matches them by alias and skips the rows it does not understand, rather than rejecting the whole file.
- 04Drop it above. It is read in place, and the count of skipped rows is shown with the result.
The exact number is taken on your traffic
This page estimates what is reachable from an export. Plugged in observe-only mode, the proxy measures route by route what routing would really give back, without modifying a single request.
