Replace API spend with a Codex subscription.
Codex Hosted runs OpenAI's Codex for you, signed in with your ChatGPT account, so your workloads bill to the flat plan instead of the API. Put in your current OpenAI bill and ProxyLLM shows the plan capacity, the $129 SaaS fee, and the monthly savings.
Put in your current OpenAI bill.
This uses your bill amount only. No token estimates, no guesswork. ProxyLLM maps your existing API spend to the Codex Hosted subscription tier that can absorb it.
Covers up to $3,500 of API-equivalent work each month.
A $3,500 OpenAI bill becomes $129/mo for ProxyLLM plus $100/mo for Codex, so you save $3,271.
