This suffers from a common pitfall of LLM's, context taint. You can see it is obviously the front page from today with slight "future" variation, the result ends up being very formulaic.

That's what makes it fun. Apparently, Gemini has a better sense of humor than HN.

I would find it even more fun if it were more speculative, misapplied uses of 'woosh' aside.

But there's no mention of fun or humor in the prompt.

Judging by the reply posted by the OP, the OP probably maintains a pretty humorous tone while chatting with the AI. It's not just about the prompt, but the context too.

I don’t ask it to be sycophantic in my prompts either but it does that anyway too.

I mean it's very funny. Just I'm laughing at the AI, not with it.

Yeah that’s very true, but I still think it’s pretty funny and original.

Either it’s formulaic or it’s original, it can’t be both.

The problem is not that it fails to be cheeky, but that "its funny" is depressing in a context where there was a live question of whether it's a sincere attempt at prediction.

When I see "yeah but it's funny" it feels like a retrofitted repair job, patching up a first pass mental impression that accepted it at face value and wants to preserve a kind of sense of psychological endorsement of the creative product.

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by jacobr1 on Tuesday December 09, 2025 @12:45PM (#46207980)
Honestly it feels like what I, or many of my colleagues would do if given the assignment. Take the current front page, or a summary of the top tropes or recurring topics, revise them for 1 or 2 steps of technical progress and call it a day. It isn't assignment to predict the future, it is an assignment to predict HN, which is a narrower thing.
Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by glenstein on Tuesday December 09, 2025 @05:43PM (#46211760)
Right, because you would read the teacher and realize they don't want you to actually complete the assignment to the letter. So you would do jokes in response to a request for prediction.

haha thats both not true, and still works as drunk nonsense.

But good job googling this and getting fooled by an LLM

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by niam on Tuesday December 09, 2025 @01:39PM (#46208735)
It fits in nicely imo. It's plausible (services re-appear on hn often enough), and hilarious because it implies the protracted importance of Leetcode.

Though I agree that the LLM perhaps didn't "intend" that.

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by keepamovin on Tuesday December 09, 2025 @11:37AM (#46207006)
I agree. What is a good update prompt I can give it to create a better variant?
Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by ehsankia on Tuesday December 09, 2025 @12:09PM (#46207477)
You could try passing it 10-20 front pages across a much wider time range.

You can use: https://news.ycombinator.com/front?day=2025-12-04 to get the frontpage on a given date.

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by lagniappe on Tuesday December 09, 2025 @12:58PM (#46208167)
This wont change anything it will just make it less evident to those who missed a day of checking HN.
Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by wasabi991011 on Tuesday December 09, 2025 @12:09PM (#46207481)
If you do an update prompt, I hope you still keep this one around!

It's formulaic yeah, but that's what puts it into the realm of hilarious parody.

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by keepamovin on Friday December 12, 2025 @02:46AM (#46241822)
Thank you. It was a great one-shot and I didn't end up doing any updates. Thrilled to see how it inspired work from: Thomas Morford (CSE @ UC Merced, thomasm6m6) who did the amazing article/thread generation (in < 100 lines of PY!): https://sw.vtom.net/hn35/news.html ; and also from Andrej Karpathy (ex-OpenAI, now Eureak Labs, karpathy) who did an interesting analysis of prescience quality of threads/commenters inspired by a reply linking the page of 10 years past to compare: https://karpathy.bearblog.dev/auto-grade-hn/

This was wonderful. 3000 points? I mean, fuck. Among the biggest posts of all time, and definitely of Show HN. Funny for me is that all the work I've done in the last 10 years, probably 100 Show HN's all different, this was by far the hugest. Could be months of work, no interest. And this thing, which dropped into my mind, probably 30 minutes, demolished them all. It's hilarious that it even beat out legitimate AI posts, and contaminated search results with future stories.

One of the funniest things for me was hearing how people tabbed away from the page, only to come back and momentarily feel it was the actual HN page. Hahahahaha! :)

All I can say is, I love you all. Watching it stay at the top for 24 hours...it felt like it wasn't something I made at first. But it was. Cool

Isn't that a common pitfall of humans too?

In numerous shows these days AI is the big bad thing. Before that it was crypto. In the 1980s every bad guy was Russian, etc.

Not a bad thing necessarily, but some part of the plot, and usually with things going awry or emphasizing the scammy nature of blockchain.

Examples: Shameless season 11, The Simpsons S31E13, Superstore season 5, the good wife S3E13, greys anatomy S14E8, big bang theory S11E9, Billions season 5, some later seasons of Mr Robot, etc

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by thomastjeffery on Tuesday December 09, 2025 @12:29PM (#46207766)
I think the most absurd thing to come from the statistical AI boom is how incredibly often people describe a model doing precisely what it should be expected to do as a "pitfall" or a "limitation".

It amazes me that even with first-hand experience, so many people are convinced that "hallucination" exclusively describes what happens when the model generates something undesirable, and "bias" exclusively describes a tendency to generate fallacious reasoning.

These are not pitfalls. They are core features! An LLM is not sometimes biased, it is bias. An LLM does not sometimes hallucinate, it only hallucinates. An LLM is a statistical model that uses bias to hallucinate. No more, no less.

That's what the OP asked for, essentially. They copied today's homepage into the prompt and asked it for a version 10 years in the future.

I think that's what makes it funny - the future turns out to be just as dismal and predictable as we expect it to be. Google kills Gemini, etc.

Humor isn't exactly a strong point of LLMs, but here it's tapped into the formulaic hive mind of HN, and it works as humor!

Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by kccqzy on Tuesday December 09, 2025 @05:56PM (#46211882)
But it would otherwise be not fun at all. Anthropic didn’t exist ten years ago, and yet today an announcement by them would land on the front page. Would it be fun if this hypothetical front page showed an announcement made by a future startup that hasn’t been founded yet? Of course not.
Re:Show HN: Gemini Pro 3 hallucinates the HN front page 10 y... by tempestn on Thursday December 11, 2025 @01:22PM (#46234986)
I don't know, I would have enjoyed a "Floopzy launches with $10B seed round" or something.
