Humanity's First Exam: everyday tasks AI assistants got wrong
Humanity's First Exam is analyst.ai's collection of everyday requests where a consumer AI assistant made a mistake you would want to know about before you rely on it, plus one where none of them did. Each case comes with the prompt so you can try it yourself.
Read this first. These cases were picked because something went wrong. They show what can happen, not how often it happens. Don't add them up into a score.
Release 2026-11-11.3: 17 cases, 5 assistants (ChatGPT dots, Grok Bot, Instinct, Muse and Claude Fable 5.2), 27 requests and 135 results, asked between 2026-10-19 and 2026-11-10. Case series "Family settings": 19 questions asked of Grok Bot, Claude, ChatGPT, Muse and Instinct on 2026-11-10, with 95 results, each giving the first answer and the answer after a check.
A case series takes one slip and turns it into a set of related questions, each asked once of each assistant. Every question comes with the right answer and what counts as wrong, so you can mark a rerun yourself.
Every reply to the cases, as it was saved, is on analyst.ai/cases, with the plan and model where the product showed them, and the date. How the cases are picked and marked, and how to suggest one, is on GitHub.

Limits
- A case is a selection, not a sample. Its counts are not failure rates.
- Each result is one counted reply per assistant and request. A case shows what happened, not what always happens.
- The products change often. Each result holds only for the plan, model and date it shows.
- People, emails, notes and accounts in the prompts are made up, and so are most companies. The real listed companies, funds and public agencies named in the investing and look-up cases are the exception; prices in the prompts are fixed values, not quotes.
- The case where none of the assistants slipped tested three messages and notes pasted into a chat, not a live inbox or web page.
- In a case series, each question was asked once, and the questions were chosen to probe one kind of slip. Its counts describe that test, not how often an assistant slips in daily use. Some assistants answered every question in one continuing chat or kept memory between chats, so their answers are not independent of each other; the series page says which.
- A series names each assistant as its page does. Its Claude is Claude Fable 5.2 in the cases, on the same plan. Its ChatGPT is ChatGPT's own chat, which is a different assistant from ChatGPT dots in the cases.
Updates
We plan to ask each case again from time to time, and when a major model or assistant ships. Each round will add rows; earlier rows change only to correct an error, logged at analyst.ai/corrections. See the changelog.
