Questions
Straight answers.
GPT keys, pricing, and the basics.
01Is this a GPT reverse proxy?
In effect, yes. Your request hits our gateway, we route it upstream to a provider serving GPT, and the response comes back the way your client expects.
02Do I need my own provider account?
No. We run the upstream accounts. One SilvR key covers GPT and the rest of the catalog.
03Can I use GPT for free?
Yes. Every account starts on the free plan with a daily allowance you can spend on any model in the catalog, GPT included.
