What it means for your Codex and ChatGPT usage
According to the pricing page, from December your plan's usage will count against one limit that covers both ChatGPT and Codex. In practice, ChatGPT use and Codex coding work will draw from the same plan limit. Heavy use of one product could leave less room for the other before you reach the limit.
The page also says Enterprise and Business can buy credits for more access. It does not say how those credits will interact with the shared limit.

How the page describes Codex access by plan
The pricing page lists limited Codex access on Free and Go, Codex on Plus with expanded Codex usage, and expanded Codex on Pro. Pro also offers a choice of three usage tiers and longer Codex and ChatGPT Work sessions.
Pro 100, Pro 200 and Pro 500 include monthly API credits, but the page does not show the amounts. The page does not say whether those API credits count toward the shared ChatGPT and Codex limit.
