Chrome Ate 4GB of Disk Space? Delete the Local AI Model and Stop It Coming Back

Sat, 27 Jun 2026 23:00:00 +0800

Short version

Some Google Chrome installations now download several gigabytes of local generative AI model data in the background. This is usually not malware and not a broken cache. It is Chrome preparing on-device AI models for browser and web features. Deleting the folder only frees disk space temporarily. The durable fix is to disable the local GenAI foundational model download with Chrome policy, then remove the already downloaded model folders.

This guide covers Windows 11, Ubuntu 26.04, and macOS 26. It includes one-click scripts, manual steps, and an agent prompt you can hand to Codex, Claude, OpenClaw, Gemini CLI, or another local operator. The scripts use native OS policy mechanisms and Chrome’s documented policy. They do not depend on third-party services and do not include real IP addresses, hostnames, internal domains, or secrets.

New Chrome Could Not Log In to Bitwarden, but Old Machines Still Worked: A Vaultwarden Compatibility Trap

Mon, 18 May 2026 10:05:00 +0800

TL;DR

The failure looked like a Chrome or Bitwarden extension problem: newly installed computers could not log in to a self-hosted Vaultwarden instance, while existing computers continued to work with the same Bitwarden 2026.4.1 browser extension. The actual root cause was server-side compatibility: the clients were using a newer prelogin endpoint, while the Vaultwarden server was still running vaultwarden/server:1.35.4-alpine, which did not provide /identity/accounts/prelogin/password.

Existing machines were likely protected by an already established login state and local cache. They did not prove that the full first-login API path was still compatible. The correct fix was to back up the Vaultwarden data, upgrade the server image to 1.36.0 or newer, and confirm from logs that the prelogin endpoint no longer returned 404.

All domains, paths, usernames, and deployment details in this article are sanitized. Examples use placeholders such as vault.example.com and /opt/vaultwarden; no internal network or private information is included.
