Transcript excerpt
0:02 If we could take at this point a bit of a tangent and talk about education and learning. If you're somebody listening to this who's a smart person interested in programming, interested in AI, so I presume building something from scratch is a good beginning. So can you just take me through like what you would recommend people do? >> So I would personally start like you said uh implementing a simple model from scratch that you can run on your computer. The goal is not if you build a model from scratch to have like something you use every day for your
0:33 personal projects. Like it's not going to be your personal assistant replacing an existing openweight model or CHPD. It's to see what exactly goes into the LLM, what exactly comes out of the LLM, how the pre-training works in that sense on your own computer preferably. Um, and then you learn about the pre-training, the supervised fine-tuning, the attention mechanism. You get a solid understanding of how things work. But at some point you will reach a limit because small models can only do so much. And the problem with learning about LLMs at scale is I would say it's
