A modern transformer block: 6 stages from input to output.
What you're seeing
Pre-norm architecture: norm first, then sub-block, then residual add. Repeat for FFN.
Same pattern at every layer; L layers stacked = full transformer.
★ KEY TAKEAWAY
Every modern transformer block is pre-norm + attention + residual + pre-norm + FFN + residual. Same pattern, L times.
▶ WHAT TO TRY
Click Next stage to walk through one block in sequence.
This pattern is used in Llama, Mistral, Phi, Qwen, Gemma — all of them.
