Claude AI users report earlier context window compaction post-update

Users are reporting that Anthropic's Claude AI is experiencing earlier context window compaction following a recent update, particularly affecting accounts with the new Chat/Cowork merge. Data from the unofficial Claude Usage Tracker Chrome extension suggests that the context window size can significantly decrease after tool use, such as artifact or code execution. While Anthropic support has confirmed the Chat/Cowork merge, they have not yet clarified whether these observed changes in compaction and context window behavior are intentional design choices or a result of bugs. AI
