What we include
Organizations that evaluate AI models or AI systems for outside clients or partners: managed and expert evaluation vendors, independent evaluators and research organizations, firms that run AI red-team or security assessments, and benchmark builders that take commissioned work. Each must have an active public website that describes the evaluation work. Evaluation software that you run yourself is covered by our sister site, bestaievals.com.
Sources
Each fact comes from the company’s own website, trust portal, or a primary release such as a company announcement or regulatory filing. Every profile lists its sources and the date we checked them.
What we do not do
We do not test evaluators, score them, rank them, or publish reviews. We do not claim partnerships or customer relationships we cannot source. Where a company publishes no price, we say “Contact vendor”. Where we found no certification, we say so and suggest asking for documentation; that is not a finding that the company lacks one.
Certifications
Listed as the company states them. Scope can differ by product, team, or subsidiary, so we recommend requesting reports.
Order
Lists default to alphabetical order. Filters and comparisons change only what is shown, not any ranking.
Updates
We re-check sources at least every 90 days and when companies announce material changes.
Commercial policy
Today we accept no payment for listings or placement. If sponsorship is introduced later, sponsored items will be labeled, kept out of editorial comparisons and filters’ default order, and disclosed on this page.
