Grok 3 Hallucination

Grok 3 Hallucination

I created a service via prompt-smithing to generate 3 most-discussed, current stories for a specific country. The prompt specified that Grok would striclty review the X.com post traffic generated by users in that country. Under Grok 2, it needed more curation that I wanted to do, so I decided to wait for Grok 3. I had been under the impression that Grok 2 saw posts in real time, but then learned it did not. Grok 3 purportedly (and it insists) does see X posts in real time.

I switched to Grok 3 as soon as my account had it and tried the prompt again. When running the prompt for The United States, I noticed that the stories were not current. One story stated that Antony Blinken was Secretary of State when he hasn’t been for over a month. Another talked about the upcoming presidential election, showing that the time frame Grok was operating with was months ago.

I then asked Grok 3 to review and refine the prompt itself to ensure that the stories it generated were current topics and actively the top stories users were discussing. It provided a more concise draft that did seem to get better results for a number of countries. Then I ran on the United States again and… the stories did not seem to be the biggest and more relevant. Rather than negotiations to end the Ukraine war or Macron’s visit to the US or the raging about DOGE, it came back with a Timberwolves’ player opting for free agency. Really?

So I asked Grok 3 to show me the posts that led it to choose these three stories. It came back with quoted posts, one for each story. One quickly notices that the length, tone and style of all three example posts were identical. As if they’d been written by the same person.

I asked for the user accounts that generated them. Grok 3 produced 3 user accounts. None were actual accounts. When I pointed that out, Grok 3 helpfully explained that it was providing representative quotes that it had assimilated from X.com posts, and the account names were also representative of the types of account IDs that would post those representative quotes.

I then explained that doesn’t work for me. I need to see real posts from real accounts. Grok 3 apologized then helpfully presented 3 more accounts stating they were actual user accounts.

They weren’t.

So there it is.

I’ll move on to some other endeavor.

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Previous and Next buttons read up and down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Previous and Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

Browsing view

View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
