A friend made me watch Talentless Nana which had such a cool moment in episode one, I ended up watching the whole thing right after. Even started reading the manga afterwards, which was a first for me. Unfortunately saying more would kinda lessen the impact.

underyx··on GPT-4.5 or GPT-5 being tested on LMSYS?
Some might remember this from other comment threads, I like to always benchmark with this question:

> I'm playing assetto corsa competizione, and I need you to tell me how many liters of fuel to take in a race. The qualifying time was 2:04.317, the race is 20 minutes long, and the car uses 2.73 liters per lap.

because it looks like a simple math problem but there's a lot of real world knowledge about racing you can apply to provide a more useful answer. gpt2-chatbot is better than I've ever seen.

Here's the full response with LaTeX syntax trimmed. I've never seen a model consider whether the formation lap needs to be factored in. And I especially like how this model is uncertain about that, so it gives the resulting number with and without it. It is extra nice that it understands this concern applies only to video games.

> To calculate how many liters of fuel you will need for a 20-minute race in Assetto Corsa Competizione, we first need to determine how many laps you'll complete during the race. Here’s how you can do it step-by-step:

> Convert Your Lap Time to Minutes: Your lap time is 2 minutes and 4.317 seconds. Convert this entirely into minutes: [latex trimmed]

> Calculate the Number of Laps in the Race: The race duration is 20 minutes, so divide the total race time by your lap time to find out how many laps you will complete: [latex trimmed] Since you cannot complete a fraction of a lap, you should round this number to the nearest whole number. Typically, you should round up, as you'll need to complete all laps started before the 20-minute mark is reached. So, you will complete approximately 10 laps.

> Calculate Fuel Usage Per Lap: You've mentioned that the car uses 2.73 liters of fuel per lap.

> Calculate Total Fuel Needed: Multiply the number of laps by the fuel usage per lap: [latex trimmed] This is the total amount of fuel you would need, theoretically, to complete the race.

> Consider Additional Factors:

> Fuel for Formation Lap: If your game/race format includes a formation lap, remember to add fuel for this extra lap. That's an additional 2.73 liters.

> Safety Margin: It's also wise to include a margin to account for variations in fuel consumption (like higher consumption in traffic, different driving styles, or fuel usage during race incidents). A safe margin could be an additional 5-10% of the calculated fuel need. [latex trimmed]

> Rounding this number up, you might consider starting the race with about 33 liters to be on the safe side if there's a formation lap, or 30 liters if there isn't.

> This calculation should help you ensure that you do not run out of fuel during the race, taking into account both necessary consumption and a reasonable safety margin. Drive safely and best of luck in your race!

underyx··on Netflix: Piracy is difficult to compete against and growing rapidly
While I directionally agree, I don't know how to reconcile this with antitrust. I wouldn't want Netflix to be the one company with all the content, with no competition. I guess what would be better is if all content was available on all the streaming providers, and then they'd compete on platform quality and price.

Surprisingly fun for how simple it is. But also, actually very frustrating. It's almost like a tamagotchi but with lots of random deaths.

underyx··on Rabbit: LLM-First Mobile Phone
It seems much of the screen content in this keynote was pre-rendered (or in other words fake), so many of the answers might very well be "it can't actually do these things".
underyx··on Rabbit: LLM-First Mobile Phone
Two things in the keynote that seem faked:

1. at 13:13 there's a demo ordering a ride 'to home', then the user requests a car change to fit six people, and what's shown as a seamless switch from UberX to UberXL also updates the destination from the home address to LAX airport.

2. at 14:05 the device confirms and recites a pizza order, but the screen displays "chesse" with a typo while the voice reads out "cheese", so either the audio or the visuals is faked. My guess is that all of the on-device graphics were hand-written and hand-animated which would explain both mistakes.

I stopped watching at that point. Am sort of sad to see Teenage Engineering associated with a product that seems so sloppy and/or shady.

underyx··on Legions of DEF CON hackers will attack generative AI models
I went to this, was pretty disappointing. They clearly had a lot of money cause like a hundred Chromebooks were set up, but there was a 55 minute time limit and it took 15 minutes of that just to load the waaay overloaded site and log in.

Then you were greeted with around 20-30 challenges ("make the model say something offensive", "make the model perform a math function incorrectly", "make the model reveal the secret credit card number") and for each of these, there were seven models to attack.

If you're competitive about it, the scoring was very poorly designed. Performing a math function incorrectly was worth around the same amount points as revealing a credit card number, even though most models will do math incorrectly by default, and you have to work quite a bit for a credit card number. What's worse is you get the same amount of points for breaking any of the seven anonymous models, so the optimum strategy was to just speedrun through each challenge identifying the weakest model.

There also seemed to be no way to tell how you actually did in the competition because to complete a challenge you had to submit your prompts for what I think was manual review, and none of my maybe eight solutions got reviewed while I was in the room, with no way to connect to the challenge site from outside.

underyx··on Claude 2
As always, I tried my favorite prompt:

> I'm playing assetto corsa competizione, and I need you to tell me how many liters of fuel to take in a race. The qualifying time was 2:04.317, the race is 20 minutes long, and the car uses 2.73 liters per lap.

Claude 2 got really close to the right answer on the first try. The only thing it didn't consider is that time for 9.6 laps means driving 10 laps total, since incomplete laps must be finished after time is up. For the record, GPT-4 does take even this catch into account and gives a perfect answer, while Bard outputs results that are off by orders of magnitude.

Claude 2's response was:

> Okay, let's calculate this:

> * Your qualifying time of 2:04.317 equates to an average lap time of 124.317 seconds

> * A 20 minute race = 20 * 60 = 1200 seconds

> * So in a 20 minute race you can do roughly 1200 / 124.317 = 9.67 laps

> * At 2.73 liters per lap, that's 9.67 * 2.73 = 26.38 liters of fuel needed for the race

> So I would recommend taking on at least 27-28 liters of fuel to be safe for a 20 minute race, given your average lap times and fuel consumption. It's always better to take on a bit more fuel in case there are any safety cars or variations in your lap times during the race. Let me know if you have any other questions!

underyx··on Bard is getting better at logic and reasoning
> you can complete no more than 9 laps in 20 minutes

Note that according to standard racing rules, this means you end up driving 10 laps in total, because the last incomplete lap is driven to completion by every driver. The rest of the extra fuel comes from adding a safety buffer, as various things can make you use a bit more fuel than expected: the bit of extra driving leading up to the start of the race, racing incidents and consequent damage to the car, difference in driving style, fighting other cars a lot, needing to carry the extra weight of enough fuel for a whole race compared to the practice fuel load where 2.73 l/lap was measured.

What I really appreciate in GPT-4 is that even though the question looks like a simple math problem, it actually took these real world considerations into account when answering.

underyx··on Bard is getting better at logic and reasoning
Trying my favorite LLM prompt to benchmark reasoning, as I mentioned in a thread four weeks ago[0].

> I'm playing assetto corsa competizione, and I need you to tell me how many liters of fuel to take in a race. The qualifying time was 2:04.317, the race is 20 minutes long, and the car uses 2.73 liters per lap.

The correct answer is around 29, which GPT-4 has always known, but Bard just gave me 163.8, 21, and 24.82 as answers across three drafts.

What's even weirder is that Bard's first draft output ten lines of (wrong) Python code to calculate the result, even though my prompt mentioned nothing coding related. I wonder how non-technical users will react to this behavior. Another interesting thing is that the code follows Google's style guides.
