About OpenAI Codex

Codex is included with eligible ChatGPT plans and shares usage, credits and limits with ChatGPT Work. Individual access ranges from Free and Go to Plus and two Pro capacity tiers. Business has published annual and monthly seat prices; Enterprise and Edu are sales-led or credit-based. API-key use is a separate path for CLI, SDK and IDE automation, billed at the selected model's API token rates and without Codex cloud integrations such as hosted code review or Slack.
