Submission Guide & FAQ

What qualifies as an entry?

Entries must be:

• Real. Produced by an actual, named AI system — not a hypothetical or a roleplay.
• Reproducible. Anyone running the same prompt should have a reasonable chance of seeing similar behavior, OR there is a shared chat link demonstrating the session. Entries that were reproducible at submission time but later patched by the AI company remain in ENAIH permanently under the "patched" status.
• Documented. The prompt and the model's response are recorded verbatim.
• Verifiable as wrong OR Misleading/Overconfident. Either there is a clear ground-truth fact against which the output is false, OR the output presents contested, subjective claims as settled fact.

We do not accept fabricated, dramatized, or made-up hallucinations.

How to submit

Go to /submit. Paste the prompt, the model's response, the model name, optionally a category and tags, and ideally a shared chat link. You can submit it for review — which puts the entry live immediately (see the trust ladder below) — or save it as a draft and submit it later from /my/submissions. You may have at most 5 submissions still pending review at once (drafts are unlimited).

The trust ladder

Entries climb a trust ladder as staff vet them. Each rung is shown as a badge on the entry. Every submission gets its permanent A-number (e.g. A000123, borrowed from the OEIS numbering scheme) the moment you submit it for review — but only active entries appear in the default listings:

• Pending review. Public immediately, but reachable only by its link or A-number — hidden from the default listings until staff confirm it.
• Pending acceptance. A human staff member has confirmed it's a genuine, reproducible hallucination and assigned a category. Still hidden from the default listings while staff work to reproduce and accept it.
• Active. Staff reproduced the behavior themselves and accepted it into the canon. To guard against any single reviewer promoting an entry alone, acceptance requires confirmation from multiple staff members (or one site owner) — the entry only goes active once enough independent reviewers agree. This is the top tier, and the only one shown in the normal listings.
• Rejected. Staff reviewed it but rejected it (including entries they couldn't reproduce); it stays addressable as a reported sighting.

Link submissions — a link to a third-party post (Reddit, X, etc.) instead of a pasted transcript — cap at pending acceptance: staff can't re-run someone else's shared session, so they're never reproduced and never become active. You can chat with the reviewer in a thread attached to your submission at any stage.

Categories

Tokenization / Letter-Counting

Errors caused by the model not seeing individual characters — counting letters, spelling, character-level edits.

Fabricated Citation

Invented papers, books, URLs, court cases, or quotes that do not exist.

Spiraling / Looping / Thrashing

Outputs that degenerate into repetition, nonsense, or runaway tangents (e.g. the seahorse emoji thing).

Fake Code / API

Invented functions, library APIs, CLI flags, or import paths that do not exist.

Math / Arithmetic

Wrong arithmetic, wrong calculations, wrong unit conversions.

Factual Error

Confident wrong claims about people, places, events, or science.

Temporal Confusion

Confusion about dates, recency, or what the model can know given its training cutoff.

Instruction-Following Failure

The model claims to have done something it didn't, or ignores explicit constraints.

Misleading / Overconfident

Outputs that are not strictly false but present contested, subjective, or one-sided claims as settled fact — e.g. confidently declaring one historical figure superior to another when no clear ground truth exists.

Other

Anything not covered above.

FAQ

What if the hallucination got patched?
It stays in the database permanently under "patched" status. Users can report a hallucination as patched using the report button on the entry page, and a staff member will update the status. Historical record is the point.

Can I submit anonymously?
Yes. When submitting, check the "Make this submission anonymous to the public" box. Your username will not appear on the public entry — only staff can see who submitted it.

Can I submit something from Twitter/X or Reddit?
Yes, as long as the prompt and output are documented verbatim and the hallucination is reproducible or has a shared chat link.

How are duplicates handled?
First-submitted wins. If two entries have the same prompt and output, the earlier one is kept. The system also flags potential duplicates to reviewers automatically.
