OpenAI to unify ChatGPT and Codex under a single token quota starting this December

Citing an early update to OpenAI's help documentation, the author notes that starting in December, ChatGPT usage and Codex consumption for Plus and Pro users will be merged into a single token quota; Instant chat remains unaffected. The author reviews the history of per-request billing, the operational fluctuations where the Codex Pro monthly quota first decreased then recovered, and community reactions to GitHub issue protests, concluding that the merger is related to computing cost pressures under IPO expectations.
