Developer builds Transformer model from scratch in PyTorch

Sparsh Sharma details the process of building a Transformer model from scratch using PyTorch, emphasizing the importance of understanding the underlying mechanisms rather than just using pre-trained models. The walkthrough covers key components like self-attention, multi-head attention, and positional encoding, highlighting common pitfalls such as vanishing gradients in RNNs and the necessity of scaling in attention mechanisms. Sharma's motivation stemmed from a desire to demystify the 'black box' nature of large language models after encountering issues while fine-tuning APIs like Groq, Gemini, and Mistral AI for the Manshverse project.
