Logs show OpenAI/Anthropic bots not crawling llms.txt yet

A developer's log analysis reveals that while OpenAI and Anthropic bots make up to 300K daily requests to site URLs, there are zero requests for /llms.txt.

This suggests that despite llms.txt being proposed as a standard for LLMs (analogous to robots.txt for search engines), major model providers have not adopted it into their crawling workflows yet. If they aren't actively seeking it, the standard likely has little impact on their current operations.
