What “Beta” means for ChatGPT Atlas
The integration path is built and tested. Real customers can attach now, but expect minor breaking changes until the 1.0 contract freeze.
How it attaches
Browser instrumentation.
ChatGPT Atlas drives a browser. The Trustvice Chrome extension (or instrumented Chromium image) observes its activity at the click and DOM-event layer.
Install the Trustvice Chrome extension (desktop) or use the Trustvice-instrumented Chromium image (headless).
- 1
Install the extension
Desktop: install the Trustvice Chrome extension from the Web Store. Headless: pull the Trustvice-instrumented Chromium image from the Trustvice container registry. We have not yet verified which of these surfaces ChatGPT Atlas exposes — if it is a hosted browser you cannot extend, use the CDP path instead.
- 2
Pair with the workspace
The first-run flow generates a workspace-scoped extension token (xt_…) bound to your browser profile.
- 3
Verify
Open any ChatGPT Atlas-driven tab. The extension's status icon turns coral when a recognised runtime is detected; records appear in Witness within a few seconds.
