What AI does CERN use?
CERN uses 2 AI tools: Sonar and Sourcegraph. 1 is confirmed by a published story, quote or press release. 1 is listed on its vendor’s own pages. Every tool links to the public page that names CERN.
Every tool, with its source
Strongest proof first. Each line links to the page behind it and its capture date.

“First public proof” is the earliest public page we have dated: a mention (“on or before”), a job post or a start the source states. Our capture dates are not adoption dates.
Questions about AI at CERN
What AI tools does CERN use?
CERN uses 2 AI tools (1 confirmed, 1 observed): Sourcegraph and Sonar.
Does CERN use Sonar or Sourcegraph?
Yes, both. Sonar: observed, the vendor shows CERN on its own pages. Sourcegraph: confirmed by a published case study, quote or press release.
Which AI tools are confirmed at CERN?
One: Sourcegraph. Each one has a published case study, a named quote or a press release.
What do confirmed, observed and signal mean?
Confirmed: a case study, a named quote or a press release. Observed: the vendor shows CERN on its own pages, for example a logo wall. Signal: a job post shows CERN’s employees use the tool, the weakest proof. Every level counts, and each line shows its level.
How current is this page?
The most recent check was on October 19, 2026. 2 of the 2 lines have been checked so far, from 2 public sources.
How does usedby know which AI tools CERN uses?
Each tool is linked to a public page that names CERN: a vendor's customer page, a published case study, a press release or a job post. We save most pages with a dated capture and check them again on each run. A tool leaves the list only after three checks in a row that no longer find CERN, and at least 14 days after it was last seen. A tool with a published case study or quote is never removed automatically.
