Merged summary
TL;DR - An accessible tutorial explains how attention, feed-forward networks, residual connections, and layer normalization combine into Transformer blocks. It connects these stacked blocks to autoregressive next-token generation in GPT-style models.
- Attention gathers contextual information; feed-forward layers transform it through expansion, GELU activation, and compression.
- Residual connections preserve signals and gradients, while layer normalization stabilizes activations in deep networks.
- Dimension-preserving blocks can be stacked repeatedly, with each layer sharing the architecture but learning distinct parameters.
- GPT models generate text token by token by converting the final hidden state into vocabulary probabilities and repeating the forward pass.
