AI2Bot
The Allen Institute for AI crawler, collecting data for open language models such as OLMo and the Dolma corpus. A rare case where the training data, the models and the crawler policy are all published openly.

A user agent is a claim, not a proof: any client can send any name. Where an operator publishes IP ranges, a reverse lookup is the only way to tell a real visit from an impersonation.
