The problem
Your API bill grows every time your agency does.
More clients, more agents, more usage. The meter climbs with all of it.
So you reach for the mini model, you trim the context, you cap what your agents can touch. The bill stays small because the product stays small.
You call that efficiency. Really, every margin point you protect is a feature you never shipped.
The fix
ProxyLLM removes the meter.
We run OpenAI's Codex on your own ChatGPT plan. Your production traffic bills to a flat subscription, not per-token pricing.
So the rationing stops. You give every client your best model, and your cost holds flat while your usage climbs.
Who it's for
Agencies and builders already paying real money to the OpenAI API, watching that number grow with every client they add.
If you have ever reached for the cheaper model to protect a margin, you are exactly who we built this for.
What you walk away with
How it runs on your stack
Exactly how Codex Hosted works on your own ChatGPT account, mapped to the agents and workflows you run today.
A way off the meter
A clear path to stop rationing models and start shipping your best work to every client you have.

Massively reduced our API bill
I run an AI receptionist agency and my experience using ProxyLLM has been amazing. Switching from the OpenAI API to ProxyLLM's hosted Codex was very simple and massively reduced our API bill. Would recommend.
What it costs
One flat plan for the whole suite. No per-token bill, no inference markup.
