Reported Shared ChatGPT and Codex Usage Limits

Reports describe a Chat-and-Work experience being tested with a small group and a planned December shared allowance for ChatGPT and Codex on Plus, Pro, and Business; Codex reportedly remains separate in the desktop app. Usage may be weighted by tokens, model, and task, with Instant chats exempt and possible extra credits; exact allowances and transition timing remain unconfirmed.
