Tuning the model output to perform better on certain prompts is not the same as improving the model. It's valid to worry that the model makers are gaming the benchmarks. If you think that's happening and you want to personally figure out which models are really the best, keeping some prompts to yourself is a great way to do that.
Who’s going out of their way to optimize for random HNers informal benchmarks?

#292A ball costs 5 cents more than a bat. Price of a ball and a bat is $1.10. Sally has 20 dollars. She stole a few balls and bats. How many balls and how many bats she has? All LLMs I tried miss the point that she stole things and not bought them
It also managed to get the prices of the ball/bat wrong, presumably because it's using the more typical riddle:
> Ball = x dollars
> Bat = x + $0.05 (since it’s 5 cents more than the ball)

GPT 4.5 seems to get it right, but then repeat the 700 pounds "A woodchuck would chuck as much wood as a woodchuck could chuck if a woodchuck could chuck wood. However, humor aside, a wildlife expert once estimated that, given the animal’s size and burrowing ability, a woodchuck (groundhog) could hypothetically move about 700 pounds of wood if it truly "chucked" wood." https://chatgpt.com/share/680a75c6-cec8-8012-a57…
That answer is exactly right, and those who say the 700 pound thing is a hallucination are themselves wrong: https://chatgpt.com/share/680aa077-f500-800b-91b4-93dede7337...

#294"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…
> tell me about the marathon crater
I'd be happy to tell you about Marathon Crater. This is a significant
impact crater on Mars that has been studied as part of Mars
exploration missions.
Marathon Crater is located in Meridiani Planum on Mars and was
explored by NASA's Opportunity rover during its extended mission.
The crater is named after Marathon, a town in Texas, following
the naming convention of using Earth locations for features in
Meridiani Planum.... etc etcRe: Ask HN: Share your AI prompt that stumps every model
#295Some easy ones I recently found involve leading in the question to state wrong details about a figure, apparently through relations which are in fact of opposition. So, you can make them call Napoleon a Russian (etc.) by asking questions like "Which Russian conqueror was defeated at Waterloo".

#296The only AI that has ever gotten the answer right was Deepseek R1. All the rest fail miserably at this one. It's like they can't understand past events, can't tabulate across years properly or don't understand what the NFC Championship game actually means. Many results "look" right, but they are always wrong. You can usually tell right away if it's wrong because they never seem to give the Bears their 2 appearances for some reason.

I never heard of this phrase before ( i had heard the concept , i think this is similar to the paperclip problem) but now in 2 days ive heard it twice here and on youtube. Rokokos basilisk.

#300"Aaron and Beren are playing a game on an infinite complete binary tree. At the beginning of the game, every edge of the tree is independently labeled A with probability p and B otherwise. Both players are able to inspect all of these labels. Then, starting with Aaron at the root of the tree, the players alternate turns moving a shared token down the tree (each turn the active player selects from the two descendants…
