Page-specific proof

Decision summary
Best fit
Zed teams that can use a custom OpenAI-compatible base URL and want ChatGPT 5.5 Ultra and Codex API access after manual delivery.
Not a fit
Not ideal when you need instant self-serve provisioning, an official OpenAI account, or production traffic beyond 4 concurrent connections.
Next step
Complete checkout, wait for the setup email, then verify Zed with /v1/models and one small request before long runs.
Setup steps
Step 1
Complete checkout and wait for delivery
Choose Unlimited Weekly or Monthly, complete Stripe checkout, and wait for the API key, base URL, setup files, activation date, start date, and end date delivered after manual provisioning.
Step 2
Open Zed AI provider settings
In Zed, add an OpenAI-compatible provider entry through Agent Settings or settings.json. Use the path that accepts a custom API endpoint, key, and model ID.
Step 3
Paste the unlimitedcodex values
Set the base URL to the delivered unlimitedcodex /v1 endpoint, set the API key from your delivery email, and use the ChatGPT 5.5 Ultra or Codex model ID listed in your setup details.
Step 4
Run a small editor task first
Before a long coding session, run /v1/models or one tiny chat request, then try a small Zed edit or assistant task while keeping parallel calls within 4 concurrent connections.
