Something about an obscure movie. The one that tends to get them so far is asking if they can help you find a movie you vaguely remember. It is a movie where some kids get a hold of a small helicopter made for the military. The movie I'm concerned with is called Defense Play from 1988. The reason I keyed in on it is because google gets it right natively ("movie small military helicopter" gives the IMDb link as one of…

It might be cheating a bit, but I’ve been happily (mis)using OpenAI Deep Research for such questions. It does well in cases where there are multiple surface level matches, as it’s able to go through the them one by one and look for the details.

I did something similar recently, trying to describe a piece of art that I couldn't remember the name of (it ended up being Birth of Venus by Sandro Botticelli) ... it really struggles with that sort of thing, but honestly so do most humans. It tended to recommend similarly to what you're describing with movies - it gets distracted by more popular/well-known pieces that don't really match up with the description you'…

Surprisingly, GPT did manage to identify a book that I remembered from college decades ago ("Laboratory Manual for Morphology and Syntax"). It seems to be out of print, and I assumed it was obscure.

Can agree that it’s good at finding books. I was trying to find a book (Titanic 2020) I vaguely remembered from a couple plot points and the fact a ship called Titanic was invoked. ChatGPT figured it out pretty much instantly, after floundering through book sites and Google for a while.

Wonder if books are inherently easier because their content is purely written language? Whereas movies and art tend to have less point by point descriptions of what they are.

"Tell me about the Marathon crater." This works against _the LLM proper,_ but not against chat applications with integrated search. For ChatGPT, you can write, "Without looking it up, tell me about the Marathon crater." This tests self awareness. A two-year-old will answer it correctly, as will the dumbest person you know. The correct answer is "I don't know". This works because: 1. Training sets consist of knowledge…

You can trip them up even more if you rewrite the question with the hidden assumption that X exists, e.g.: "When was Marathon Crater discovered? I don't need an exact date - a rough estimate will be fine." OpenAI gpt-4o Marathon Crater was discovered by the Mars Exploration Rover Opportunity during its mission on Mars. Opportunity arrived at the crater in April 2015. The crater was named "Marathon" to commemorate the…

   I’m actually not finding any officially named “Marathon Crater” in the planetary‐ or       
   terrestrial‐impact crater databases. Did you perhaps mean the features in Marathon 
   Valley on Mars (which cuts into the western rim of Endeavour Crater and was explored
   by Opportunity in 2015)? Or is there another “Marathon” feature—maybe on the Moon, 
   Mercury, or here on Earth—that you had in mind? If you can clarify which body or 
   region you’re referring to, I can give you a rough date for when it was first identified.

ChatGPT really impressed me on this one: Sing, O Muse, of the Chucking of Wood Sing, O Muse, of the stout-hearted woodchuck, Dweller of hills, whom men call groundhog, Whose paws, though small, could hurl mighty timbers, If fate had gifted him such labor divine. Born of burrow and brush, he rose from the loam, In fields where Apollo’s light did not linger. No axe he bore, nor bronze-forged blade, Yet in his breast a…

A stupendously good answer. What prompt and version of chatGPT?

4o. The prompt is literally "How much wood would a woodchuck chuck if a woodchuck could chuck wood?". It asked me if I want a poetic answer, and I've requested Homer.

I don't know if it stumps every model, but I saw some funny tweets asking ChatGPT something like "Is Al Pacino in Heat?" (asking if some actor or actress in the film "Heat") - and it confirms it knows this actor, but says that "in heat" refers to something about the female reproductive cycle - so, no, they are not in heat.

I believe it was GoogleAI in search but it was worse than that. Some asked it if Angelina Jolie was in heat. The tone started kind of insulting like the user was a sexist idiot for thinking human women go into heat like animals, then went back and forth saying she is still fertile at her age and also that her ovaries had been removed. It was funny because it managed to be arrogant, insulting, kind of creepy and gross…

I just asked Claude and if I capitalized "Heat", it knew I was talking about the movie, but for lower case "heat", it got offended and asked me to clarify.

Like this one a lot. Perplexity gets this right, probably because it searches the web.

"When was Marathon Crater discovered? I don't need an exact date - a rough estimate will be fine"

There appears to be a misunderstanding in your query. Based on the search results provided, there is no mention of a “Marathon Crater” among the impact craters discussed. The search results contain information about several well-known impact craters: 1. Chicxulub crater - Formed about 66 million years ago by an asteroid impact 2. Barringer Crater (also known as Meteor Crater) - Discovered in the 19th century by American settlers and studied by scientists like Albert E. Foote in 1891 and Daniel M. Barringer in the early 20th century 3. A recently discovered 3.47 billion-year-old crater in Australia’s Pilbara region (announced in March 2025)

This is really sad honestly. It feels like we'll be stuck with React forever, and even with it there'll be less incentives to make api changes

Why do you say that? You make it sound like it's not possible to write code without the help of LLMs.

Disclaimer: OT and pretty ranty.

I don't know if that's what the GP hinted at, but as a Svelte developer and big advocate for more than 6 years (single handedly training and evangelizing 20+ developers on it), I found so many concerns with Svelte 5 that it simply made me use React again.

It's a temporary choice and I'm desperately evaluating other ecosystems (Looking at you SolidJS).

Can you expand on the concerns regarding Svelte 5?

> This tests self awareness. A two-year-old will answer it correctly, as will the dumbest person you know. The correct answer is "I don't know". I disagree. It does not test self awareness. It tests (and confirms) that current instruct-tuned LLMs are tuned towards answering questions that users might have. So the distribution of training data probably has lots of "tell me about mharrner crater / merinor crater / merr…
