But what is a GPT? Visual intro to transformers | Chapter 5, Deep Learning Unpacking how large language models work under the hood Early view of the next chapter for patrons: https://3b1b.co/early-attention Special thanks to these supporters: https://3b1b.co/lessons/gpt#thanks To contribute edits to the subtitles, visit https://translate.3blue1brown.com/ Other recommended resources on the topic. Richard Turner's introduction is one of the best starting places: https://arxiv.org/pdf/2304.10557.pdf Coding a GPT with Andrej Karpathy https://youtu.be/kCc8FmEb1nY Introduction to self-attention by John Hewitt https://web.stanford.edu/class/cs224n/readings/cs224n-self-attention-transformers-2023_draft.pdf History of language models by Brit Cruise: https://youtu.be/OFS90-FX6pg Paper about examples like the “woman - man” one presented here: https://arxiv.org/pdf/1301.3781.pdf ------------------ Timestamps 0:00 - Predict, sample, repeat 3:03 - Inside a transformer 6:36 - Chapter layout 7:20 - The premise of Deep Learning 12:27 - Word embeddings 18:25 - Embeddings beyond words 20:22 - Unembedding 22:22 - Softmax with temperature 26:03 - Up next ------------------ These animations are largely made using a custom Python library, manim.
