AI2Bot

Collects web text for Ai2's open datasets used to train open language models such as OLMo.

AI2Bot is operated by Allen Institute for AI and classified here as model training. These agents collect text and images that may end up in a training corpus. Disallowing one withholds new content from the next model. It does not withdraw anything collected before the disallow, and it does not remove the site from any answer engine.

Disallowing ai2bot withholds content crawled from that point on from Allen Institute for AI's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

Allen Institute for AI runs no other agent in this registry.

Does blocking AI2Bot remove me from Ai2's open datasets?

No, not by itself. AI2Bot collects content for training, not for the index that answers questions. Allen Institute for AI operates no separate answer crawler in this registry, so there is no answer surface to lose here. Content collected before the disallow is not withdrawn.

How do I verify AI2Bot requests are genuine?

Allen Institute for AI publishes neither reverse DNS names nor address ranges for AI2Bot, so a request carrying this user agent cannot be authenticated. The string is trivially spoofed and is routinely reused by unrelated scrapers. Treat it as a hint, rate-limit by source address, and do not grant it access you would not grant an anonymous client.

See whether your robots.txt admits AI2Bot today, and whether your edge agrees with it.
