from their promotional material:

>> Why is the sky blue? > The sky is blue due to an optical illusion called the Rayleigh Scattering

Rayleigh Scattering is not an illusion but an effect.

> […] particles are made up of tiny blue and violet particles that cause the light to bend in a particular way.

ugh. no, there are no "tiny blue" particles in the sky.

That was the point. That example is meant to demonstrate that the model that trained for 4 hours can imitate a conversation but isn't actually anywhere close to being useful.

Where did you find that?

Aha, thanks!

not sure why you are being downvoted. That 'explanation' of Rayleigh scattering is just wrong.
simonw 1 day ago|||
Because that explanation is expected to be wrong. This is a partially trained tiny model, Andrej shared that obviously incorrect explanation to emphasize that the model is not trustworthy or useful at that stage.

Downvoted for being obvious in context / missing the point and getting worked up about it. He even said it's like talking to a kindergartener.

Has the word ChatGPT become generic? This has nothing to do with OpenAI's ChatGPT.

It's a reasonable shortcut for what this project provides: training code, inference code and a ChatGPT-style web interface for chatting with the model.

I believe you that you just meant this as an interesting example, and in that sense were engaged in curious conversation (generally what we want here). But the amount of provocation in the comment is so high, and the amount of information so little, that it ends up on the wrong side of "Eschew flamebait. Avoid generic tangents." (https://news.ycombinator.com/newsguidelines.html). In other words: not gonna end well.

Controlling culture, yes but wild pivot to mention that criminal alongside Karpathy.

not a particularly ethical guy and I wouldn't hold him up as a example of morality but the guy hasn't actually been found guilty YET. Multiple courts have tried. You'd think that for a guy under as much scrutiny as him that they would have SOMETHING to pin him on by now.

Innocent until PROVEN guilty is a foundational legal precedent for a reason.

He is definitely guilty of being a waste of human life, a massive asshole and a general detriment to society worldwide. Don’t need a court to prove that.

There are 6 criminal cases against him in several countries, let’s see how they pan out - but regardless he is not an innocent person.

I mean just an example. He obviously wasn't the most ethical person. Depends how you do it

Neither are Stalin, Netanyahu, Pol Pot, Hitler, Charles Manson et al.

Way to derail the conversation. Focus on the positive people and their legacy of time, sharing, positive energy and contributions to society

not derailing, just pointing out effective ways of producing good which is what i was responding to. i think its good for people to be aware of this. those people are all examples of people who have influenced culture for bad. you can do it for good: bryan johnson, civil rights leaders, leftist streamers. andrew tate was just the most effective, recent, and obvious one which is why I pointed him out.

if the AI bubble is anything to be compared to, how is 100$ worth anything in GPT terms.
