OpenAI is changing ChatGPT’s interface by merging its separate “Chat” and “Work” tabs. In parallel, OpenAI will combine usage allowances so that ChatGPT usage draws from the same allocation pool as Codex.

Multiple outlets report that the rollout is scheduled to begin with shared usage limits taking effect in December for certain paid tiers, including Plus, Pro, and Business. ZDNet also adds that the change will be tested with select users before wider release. The New Stack and TechCrunch emphasize the practical impact of the combined limits, framing it as competition or trade-offs between ChatGPT and Codex usage.

Across coverage, the main points are consistent: the tab merger is tied to a shared usage model. Differences are mainly in framing—some outlets lead with the interface change, while others foreground the shared allowances and how it affects how users split time between ChatGPT and Codex.
