Published results, each linked to its dated source. We quote, we do not score.

What AI tools does LMArena use?
LMArena uses 1 AI tool: E2B. 1 is confirmed by a published story, quote or press release, and none is listed on the vendor's own pages.
How does usedby know which AI tools LMArena uses?
Each tool is linked to a public page that names LMArena: a vendor's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A tool leaves the list only after three checks in a row that no longer find LMArena, and at least 14 days after it was last seen. A tool with a published case study or quote is never removed automatically.
