“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.
In Rex's own words
Published results, each linked to its dated source. We quote, we do not score.
The biggest value prop of evals for us is being able to swap a different model in and out with confidence, either different models from the same provider or models from different providers, without the risk that outcomes are suddenly going to change.Questions about AI at Rex
What AI tools does Rex use?
Rex uses 1 AI tool: Braintrust. 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 Rex uses?
Each tool is linked to a public page that names Rex: 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 Rex, and at least 14 days after it was last seen. A tool with a published case study or quote is never removed automatically.
