Plans and practical limits

Official guidance includes Codex across ChatGPT plans, including Free and Go, with different usage limits. Codex Cloud is limited to eligible paid and organizational accounts, excludes Free and Go, and depends on rollout and workspace settings.

Managed as a coding-workflow product; general ChatGPT conversation does not establish every cloud entitlement. No client was installed or paid plan tested for this profile.
