Thanks to OpenAI the Great Benefactor

At peak I subscribed to several plans at the same time, but couldn’t use them all up, wasting at least half of the few hundred bucks every month. OpenAI recently opened codex cli to free users, with a certain free weekly quota. Those familiar with codex know its quota is very different from claudecode’s, and is extremely durable. I myself have 6 accounts connected behind a cli proxy, and using only the free tier already basically meets my needs. Some share that free accounts may have model quantization and reduced intelligence; I also have an account in an enterprise team, and later I’ll carefully test whether free GPT-5.3-codex differs from the paid one. The tool used for access is cliproxy, which acts as a hub that supports multiple account logins. Codex connects via the sk-API provided by the hub, enabling flexible automatic account switching.
