Starting point is 00:01:44 is they started adding more and different kinds of data sets there. Starting point is 00:02:09 You can like logic. Starting point is 00:02:28 And we take it for granted as human beings that we can do some common sense reasoning. Starting point is 00:02:51 We're like intuiting why this works so well. Starting point is 00:03:15 Then, this is really important, it was fine-tuned Starting point is 00:03:50 but just basically the Internet. Starting point is 00:04:10 on labeling data from humans. Starting point is 00:04:27 a question uh for example you could do uh generate a joke in the style of joe rogan right and you Starting point is 00:05:04 So it's not actually, Starting point is 00:05:21 plus reinforcement learning, Starting point is 00:06:01 is eerily similar to the The plot of Ex Machina. Starting point is 00:06:16 That dude's badass. Starting point is 00:06:23 Alex Garland, the director. Starting point is 00:06:32 But that scene where he's... Starting point is 00:06:46 Which one?
