Instant chat is unlimited. Medium, High, and Extra High use different reasoning efforts, but they all use GPT-5.6 Sol and have the same rate of 10 credits per message. Selecting a higher reasoning effort does not increase the per-message credit rate. Pro uses GPT-5.6 Sol Pro and is charged at 50 credits per message.

Codex credit policy updated: free Luna inference clause removed, auto-upgrade to Medium at flat 10-credit rate introduced.
OpenAI's Codex/ChatGPT pricing documentation removed the paragraph stating 'Requests that use GPT-5.6 Luna do not consume credits' and the separate automatic-reasoning credit allowance language. The replacement consolidates into a simpler model: Instant may automatically switch to Medium when more reasoning is needed, at the standard 10 credits/message rate (GPT-5.6 Sol). Users relying on free Luna inference or predictable auto-reasoning behavior are affected by this policy consolidation.
