OpenAI token optimisation

Spend less on OpenAI with one endpoint change.

Varion removes safe repetition, unnecessary history and irrelevant tool schemas before requests reach OpenAI. You keep the same application and verify the savings yourself.

One measured test, not a guaranteed average. Results vary by workload.

Integration takes minutes

OpenAI-compatible applications change their API base URL and use a Varion key. The rest of the application can remain the same.

Tool pruning

Sends only tool schemas relevant to the current request.

Common questions

Does Varion guarantee 29.91% savings?

No. That percentage came from one verified OpenAI test. Each customer can run real A/B tests on their own workload before production.

Does Varion pay my OpenAI bill?

No. Customers use their own OpenAI key and pay OpenAI directly. Varion credits cover only the Varion savings fee.

Do you store the OpenAI key used in the free tester?

No. The website tester uses it for the live calls and does not store it. Production customers may choose to save their key encrypted in their private account.

What happens if optimisation is unsafe?

Varion can pass the original request through unchanged. Unverified workflows default to passthrough.

Can I verify usage in OpenAI?

Yes. The test calls appear in the customer's own OpenAI usage records, while Varion shows the side-by-side metrics.
