Estimates are guesses. Your bill is what really happened. The free bill check takes one month of your OpenAI or Anthropic usage and prices exactly that usage on withConflux, model by model.
Key takeaways
- Upload a usage export (CSV), up to 5 MB.
- The file is read and dropped. Only the report is kept.
- You see the same models on your own keys and on ours.
- Any saving comes from a cheaper model for simple work, shown as an example.
How it works
1. Export. OpenAI: the usage export from your dashboard. Anthropic: the usage export from the Console.
2. Upload. Drop the CSV on the bill check page with your email. We match each model in your file to our live model list.
3. Read. The report shows on the page right away and comes to you by email.
What the report shows
| Line | What it is |
|---|---|
| You paid | Your file's own costs when it has them, otherwise the provider's list price. |
| Your keys | The same usage on your own OpenAI or Anthropic keys through withConflux: what you pay now, plus €19 a month for the gateway. |
| Our keys | The same usage on our keys: the provider's price plus a small margin, no provider accounts needed. |
| Example change | What it would cost if half of the calls to a model moved to a cheaper model of the same provider. |
Honest by design
The same model never costs less on our keys than going direct to the provider, and the report never says it does. What withConflux adds is one key for both providers, cost per key and spend caps. The only saving in the report comes from using a cheaper model for simple work, and it is labelled as an example, because only you can decide which calls are simple.
A good first move: take your highest-volume endpoint, try a smaller model on the same prompts, and keep it if the answers hold. The compare pages show which current models are cheaper and by how much.
What we keep
The CSV is read in memory and never stored. We keep the report and your email so we can send it. If you tick the box, we'll also send the occasional product update.
