The change affects Plus, Pro and Business subscribers. More demanding models and complex tasks will consume a larger share of the pool, though OpenAI hasn't disclosed its size. Instant chat mode is exempt. Subscribers will see a combined remaining allowance and reset time in ChatGPT's settings. The move follows OpenAI's October 29 reversal of a controversial halving of Pro 200 usage limits, and one forum user warns that doubled allowances won't mean more usable capacity once ChatGPT and Codex compete for the same pool. ## Full article daily.dev links to this article rather than hosting it.
