The Attention Computation — Inside the Score

Companion dataset for Episode 13 of EXD: the attention mechanism.

One score matrix, one softmax, one weighted blend. This notebook loads Qwen3.6-35B-A3B, runs it up to a real full-attention layer, and reconstructs the entire attention computation by hand — QK Norm, RoPE, QKᵀ, causal mask, softmax, weighted sum, gate, and output projection — verified bit-for-bit against the model's own output.
