OpenAI Codex
OpenAI Codex is included as part of your ChatGPT subscription and does not require a separate purchase. It is available across multiple plan levels, each with different usage limits.
ChatGPT Plus costs $20 per month and includes Codex with usage limits that allow about 30 to 150 local messages or 5 to 40 cloud tasks every 5 hours. This plan is best for developers working on a few focused coding sessions each week.
ChatGPT Pro costs $200 per month and provides significantly higher limits, allowing about 300 to 1,500 local messages or 50 to 400 cloud tasks every 5 hours. This plan suits developers who need Codex throughout their full workday across multiple projects.
Business, Education, and Enterprise plans include the same per-seat limits as Plus. However, plans with flexible pricing can purchase additional credits to go beyond included limits. For automatic pull request reviews on all repositories, flexible pricing is required.
