Multiple outlets report that recent Google Chrome updates may automatically download sizable on-device AI model files that can consume significant local storage—up to about 4GB on some systems. The storage usage appears linked to an on-device model file (described by some sources as weights.bin) placed in Chrome’s system folders. Users who notice unexplained reductions in available disk space are connecting the change to Chrome rather than other applications.
Ars Technica and other reports note that the underlying AI model itself is not necessarily brand new, but confusion can arise because users may not expect additional local files to be installed. Lifehacker and The Verge both describe practical steps to address the issue, including ways to stop or limit the downloading and to reclaim storage.
Overall, the reports agree that the behavior is tied to Chrome’s AI features and that storage impact depends on system configuration and available space. The accounts emphasize that the storage increase can be mitigated, but users may need to review Chrome’s settings or model download behavior to prevent future downloads.
