Cheapest GPT / OpenAI API Relays, Ranked
84 relays listed · sorted by lowest minimum deposit
This ranking sorts every OpenAI-supporting relay by minimum deposit, lowest first, so you can start testing with the smallest possible commitment.
GPT usage tends to run high-volume, and the multiplier is what actually drives your total cost. Test with a low-minimum relay first, then settle on whichever combines a low multiplier with solid reliability.

How to choose one
A low minimum deposit is the cheapest way to verify a relay's model access and response speed before committing.
At GPT's usage volumes, the multiplier has an outsized effect on total cost — always prioritize it for your long-term relay.
For high-frequency calling, confirm the relay's stability under load before relying on it.
Frequently asked questions
How do I find a cheap GPT API relay?
Sort by this ranking's minimum deposit, then cross-check the multiplier to land on the best overall value.
What multiplier counts as cheap for GPT relays?
A 1x multiplier is closest to official pricing; anything above 2x needs careful evaluation before committing to volume usage.
How do I judge a GPT relay's reliability?
Load-test during peak hours with a small amount first, then commit to whichever relay holds up under concurrency.
