Anthropic Claude Limits Page Updated: Model References and Project Control

Detected September 23, 2026, 05:15 UTC · How usage and length limits work

References to specific Claude Opus model versions were updated from 'Opus 5' to include 'Opus 5.5', and the description of organizational project control changed from 'Disable public projects' to 'Control project sharing'.

The 'How usage and length limits work' page from Anthropic, which typically outlines the operational constraints and behavioral aspects of Claude, has been revised. One key change involves the explanation of why Claude might switch models during a conversation, specifically updating the model version cited from 'Opus 5' to encompass 'Opus 5 or Opus 5.5'. This indicates that the system's behavior regarding model switching might now apply to a newer or additional iteration of the Opus model. Furthermore, a section concerning organizational settings for projects has been rephrased. Previously, the focus was on 'Disable public projects for your organization'; now, it broadly addresses 'Control project sharing for your organization'. This suggests a shift from a binary disable option to a potentially more nuanced or comprehensive set of controls over how projects are shared within an organization. The update also added a new question titled 'What is a limit reset?', indicating that the page now covers this topic. The precise mechanics or implications of 'Control project sharing' compared to 'Disable public projects' are not detailed in these line changes alone.

We compare this page once a day and record every difference. The text above is written by Claude Network from that comparison; none of it is copied from the source.
