Verified secondary · source: openai.com
Direct fetch of openai.com/chatgpt/pricing returned HTTP 403; confirmed via 2+ third-party trackers instead. 'Included with ChatGPT Plus/Pro from $20/mo' is accurate but incomplete: Codex also has limited access on Free ($0) and Go ($8/mo), both missing cloud task delegation, so Plus ($20/mo) remains the real practical entry point as the site copy implies. Billing changed in April 2026 from per-task to a token-based credit system; Pro split into Pro 5x ($100/mo) and Pro 20x ($200/mo). A separate uncapped pay-as-you-go path exists via an OpenAI API key at standard per-token rates. Exact usage-cap numbers and a claimed Business-tier PAYG discontinuation date rest on single sources, not independently corroborated. 2026-09-24: the top-line price and entryPaid now start at Go ($8/mo), correcting a listing that named Plus ($20/mo) as the cheapest plan although Go includes limited Codex access.
