The catch
Could not be re-verified on 2026-10-08: docs.clarifai.com no longer resolves and www.clarifai.com does not respond. Nebius has announced that Clarifai's core team joined Nebius and that it licensed Clarifai's inference technology. Treat this entry as likely discontinued. Previously recorded: SMS phone verification to claim a one-time $5 credit that expired 30 days after grant.
