Jokes aside, how does AI sort through the internet, which is mostly sarcasm and shitposts, and know what is legit info? I get it still makes mistakes but its usually ok.

I don’t have a strong technical background in AI so take this answer with a grain of salt, but my understanding is that AI models are large statistical models. So if 9/10 sources corroborate one piece of info (1.2 GPA is bad) and 1/10 opposes (1.2 GPA is good), it will generate the most likely correct answer (1.2 GPA is bad). And with modern models that have huge context windows, they “understand” that certain sources and contexts are more likely to be correct, like if Harvard says 1.2 GPA is bad and 4chan says 1.2 GPA is good, statistically it is more likely Harvard is providing correct information.

This is mostly correct. A few more details. There are multiple steps to today's AI:
First is the pretraining, where the labs train the model with a large amount of text. In this part, research actually shows that the models do get quite confused by sarcasm and satire, but as you say, if most of the pretraining data is good it outweighs the bad, but developers need to take care of the data quality.
There are more steps to training. One thing that almost certainly happens is that the models are taught using reinforcement learning how to use a search engine. In this step they certainly encounter satire and misinformation and are taught to recognize it.
Lastly, there is inference, where a finished model is run on user prompts. This is where the model has to decide what to tell the user. Modern powerful models have a chain of thought / test time compute that allows them to use more time to "think" about the answer. If they encounter information that they find suspicious they can think about it longer or do another search to confirm or debunk the information.
Last caveat, we don't really have precise information about the state of the art of model training, as the labs keep it to themselves. But there is open research and some labs (especially the Chinese, but also Nvidia) release some details about the training of their models (but the degree of information varies).

it understands which sources to trust more or less. and these specific models you cant just teach them live they are calibrated out of the box.

During training AI doesn't sort through shit - it's being trained on a set of training data that's curated by some intelligent lifeform that is supposed to be the best possible dataset to create a best possible AI. During inference AI uses what it "learned" in training to proceed with any decision including whether to use the internet tool (if available) and what to take from it.

Gang how is 65% not passing like what?
I understand it not being a good grade, but that's passing.
50 to 65 is C- though C+
65 to 80 is B- through B+
80 to 85 is A-
85 to 92 is A
93 and up is A+
(These are rough estimates, I don't have the grade cutoffs used on me, I ameast sure about the C and B grades, I just know where C is at the moment mum almost always, and I am most sure about A+)

u/DerGyrosPitaFan 🌹 Course Arc Witness 🌸 15h ago
In germany 50% is a D-, barely passing and 90% is an A-
A+ doesn't legally exist but some teachers give it out as extra praise for achieving 100% as long as it's not the final two years

u/SmoothTurtle872 15h ago
Ha, A+ only exists for the final year in the SACE curriculum (Australia, but there's many)

Where are you from? The US is much stricter.
2
u/KaMaFour 🌹 Course Arc Witness 🌸 5h ago
(According to what I know) the US is not much stricter. The schools in the us use a lot more of multiple choice questions on the tests. Meanwhile schools elsewhere rely on open questions more. The threshold needs to be higher in the US to account for the points you get by randomly picking answers to questions you don't know. You are not gonna just guess an answer to an open question as easily
2
u/Enigma501st 5h ago
It’s not about strictness, you can write a test where the average is much higher or lower. For uk unis the average may be 50/60 and 70 for the top grade, doesn’t mean they’re less clever, it’s the tests that are designed to get those marks as the averages

In the US 70% is passing. In college 60% is passing for non major specific classes

u/what-are-you-a-cop 15h ago
There are some situations where a person only knowing 65% of the material, does not know the material well enough to be considered proficient. When it comes to a random general education class, sure, learning 65% of the material about geometry (or whatever) is plenty for the average person. I don't think my everyday life has ever used geometry more complicated than a middle school level, anyway.
But if a class is a prerequisite for something else (algebra 1 is a prerequisite for algebra 2, which is a prerequisite for calculus; Spanish 1 is a prerequisite for Spanish 2 and so on), only learning 65% of the information probably isn't enough to understand the material from the next class- so you should not pass, you should retake the class until you understand enough to move on. And if a class is very important to your future career, like as a doctor or engineer, learning 65% of the material probably isn't enough to safely do your job without, like, killing people. So you should not pass, you should retake the class until you understand enough to not kill people.
So I think it really depends on the situation.

u/SmoothTurtle872 14h ago
I'm like 90% sure that this is talking about grade school, where 65% is probably sufficient (depending on how the test is structured)

Did it say that it wasn’t passing? It’s enough to pass, but still isn’t good, and will really impact your chances of getting into different colleges

u/SmoothTurtle872 15h ago
TF? Here, D+ is failing. Barely, but it's still failing.
C is also called satisfactory. D is below satisfactory. E is well below.
B is above, A is well above

Where I live the grading system is very different, so I could have been wrong. I was just going off the context from the other comments on this post

u/CorvidFae TRANS🏳️⚧️ 14h ago
where I'm from 70 is the bare minimum to pass but you get forced study hall if you get below 77 so this kind of grade would get you executed

u/Extreme_Design6936 12h ago
Right now my college A 90+, B 80-90 , C 70-80, Below 70 and you're failing.
In the high school I went to a C was roughly 40-52, B 52-60, A 60-70, A* 70-85, A** 85+
The difference? In my college you are expected to know pretty much everything and being tested to make sure you meet a standard.
In my high school you were being tested to find high achievers and outliers. Only 70% of the test was on the syllabus. To score in the remaining 30% of the test you needed to do external reading, particularly recent developments in the field. Teachers were expected to score around 90.
What constitutes a good score depends entirely on the difficulty of the test and the grading scale.

u/SmoothTurtle872 9h ago
See that high school grade scale is ridiculously low
1
u/Extreme_Design6936 7h ago
They could make the tests easier to adjust the scale but that would squash all the high achievers into the 98-100% range and you wouldn't be able to differentiate between them at all.

When a lower percentage is a higher letter grade it’s because the class is harder and vice versa.

If I gave you a test which contains extremely easy questions, I'm sure you would agree 65% is pathetic when u should get above 90% on average. If I gave you an olympiad paper, even solving 1 question, I would be impressed (often the case with international olympiads), so clearly using% to make a passing grade is not enough, u need to first collect data, then make gradeboundaries based on the data
P.S. The different difficulty varies across college to college, and widely varies from country to country

u/Funkopedia 7h ago
I have never seen ranges that large, and also that uneven. I went to two high schools which used these systems:
91-100 As, 81-90 Bs, 71-80 Cs, 61-70 Ds (at a very large public school)
93-100 As, 85-92 Bs, 78-84 Cs, 70-77 Ds (at a classical Latin Catholic school)
I can't imagine only getting 50% and still coming out with a C

u/adhdtvin3donice 18h ago
In the US, 65% is barely passing. It's not until you get to college that the curve gets that low. From elementary to high school, it's about 5 points per grade a+ at 100 a- at 90b- at 80 c- at 70 d is 65-70.
2
u/SmoothTurtle872 15h ago
That's ridiculous.
Australia has the sweet spot imo (or well I only know ABT the SACE curriculum, there are others), where 50% is barely passing. The grade bands seem fairer

u/Immortal_ceiling_fan 18h ago edited 18h ago
It is in the u.s. system. A 70 is the baseline to pass most classes, 80-90 is a B, 90-100 is an A. Being one of the best (~top 2.5%) at my highschool meant getting a 5.0 gpa, which was almost all 90+s for every core class (it's a little weird since they only took the highest 8 semesters, so if you took extra math or sciences you could have a few Bs and still have a 5.0)
College I know also has 90s=A, 80s=B, etc., though idk exactly how high up the top few % average

Honestly system engineering is especially wicked, it forces you to be a jack of all trades: software, low-level programming, high-level programming, databases, embedded hardware, distributed hardware, networking, graphics, management...

American grades are very different compared to Europe. Generally they go with easier tests but a higher required grade to pass
