ChatGPT Plus users report "Unlimited Core" feature removed or limits depleting faster

**SHORT SYNTHESIS**

Users on Reddit are reporting that OpenAI's "Unlimited Core" feature—apparently a ChatGPT Plus benefit—has either been removed from product listings or is no longer functioning as advertised. Two threads indicate the feature is either missing from the Plus tier description or that usage limits are depleting unusually quickly, though the exact nature of the change remains unclear from the posts themselves.

Discussion is sparse and fragmented. One user reports the feature is "no longer listed"; another observes usage limits "disappearing insanely fast," suggesting either a technical issue, a silent removal, or a change to how limits are calculated. No mainstream coverage exists, and the Reddit threads contain limited detail about what "Unlimited Core" specifically is, when it was offered, or what OpenAI has officially stated about any change. Users appear to be comparing notes on a perceived shift in service terms, but there is no verified explanation from OpenAI or detailed technical breakdown in the available posts. The gap between user observation and official clarity is substantial.
