AI agents struggle to access site info as only 4 of 11 platforms serve /llms.txt

By PulseAugur Editorial · [1 sources] ·

A test of 11 launch platforms revealed that only four responded to a request for an `/llms.txt` file, which is intended to inform language models about a website's content and structure. The test, conducted on October 19 and again on October 29, showed that the landscape is evolving, with some platforms changing their responses. Uneed served the largest file, while BetaList updated its response to include a well-organized file.

    I checked 11 launch platforms for an llms.txt. Four answered, one sent a challenge page

    <p>On October 19 I ran a small, boring test: fetch <code>/llms.txt</code> from the root of 11 launch platforms and directories and see who answers. Ten days later, on October 29, 2026, I ran it again before writing this up. The picture had already moved.</p> <p><a href="https://l…
