What it means

OpenAI is merging the usage limits for its two products, ChatGPT (the conversational assistant) and (the code-generation model). Previously these had separate quotas, but now they will share a single usage pool, meaning that time spent using ChatGPT counts against the same limit as calls to the Codex API. This is likely a change to simplify billing or to encourage cross-usage.

Accuracy & sourcesSourced

The claim is based on a user post on Hacker News that points to an official OpenAI announcement (the provenance tier is primary source). Assuming the post is accurate, the core fact is solid, but without the exact release text we cannot confirm the effective date or whether it applies to all tiers.

How new

This appears to be a genuinely new policy change, with no indication of recirculated older material.
