If you have used Codex before and want to preserve chat history, archive it first.
Use the default or codex token group when possible.

Download the correct CCSwitch version for your OS.

Open CCSwitch, choose Codex, and click the + button in the top-right corner.

Set the provider name to ai-one and leave the website field empty.

Open https://ai-one.vip and copy your token from the token management panel.

Paste the copied key into the API Key field.

Set the API request URL to https://ai-one.vip/v1 and save the config.

Use the connectivity test to confirm requests work.

Turn on the switch to enable this config.

Open Codex and sign out first if you already logged in before.

After restarting Codex, choose the API key login option.

Paste the token copied from ai-one.vip.

Archive old sessions first if needed.

After switching, restore old backups when necessary.

You can now use the selected model inside Codex for development and chat.
