Official docs
AI2Bot collects web content for the Allen Institute for AI (Ai2), the nonprofit behind open models like OLMo and open datasets like Dolma. Content it gathers can end up in openly released research corpora — meaning a block here is a decision about open research datasets, not just one company's product.
Does AI2Bot respect robots.txt?
Ai2 documents the crawler and honors robots.txt; as a research nonprofit it has strong incentives to stay compliant.

Should you block AI2Bot?
Blocking AI2Bot opts your content out of Allen Institute for AI's model training — a legitimate choice for original content you don't want reproduced by AI. The trade-off: models trained without your content are less likely to know your brand or recommend it unprompted. There is no direct traffic loss today, since training crawlers don't send visitors. See our guide on whether to block AI bots for the full decision framework.
