Inside AlphaFold 2 and AlphaFold 3
The two architectures side by side: AlphaFold 2 refines an MSA and a pair representation through 48 Evoformer blocks and builds the chain with a structure module; AlphaFold 3 keeps a lighter 4-block MSA module, 48 Pairformer blocks and generates atom coordinates with a diffusion module, for complexes of proteins, nucleic acids, small molecules and ions.

Questions
What does the “Inside AlphaFold 2 and AlphaFold 3” template show?
The two architectures side by side: AlphaFold 2 refines an MSA and a pair representation through 48 Evoformer blocks and builds the chain with a structure module; AlphaFold 3 keeps a lighter 4-block MSA module, 48 Pairformer blocks and generates atom coordinates with a diffusion module, for complexes of proteins, nucleic acids, small molecules and ions.
What are the steps shown in “Inside AlphaFold 2 and AlphaFold 3”?
1. Inputs: Genetic and structure database searches give an MSA and templates. 2. Evoformer: 48 blocks exchange information between the MSA and pair representations (Jumper 2021; block count from Abramson 2024). 3. Structure module: Builds the chain from residue frames and side-chain angles (AlphaFold 2). 4. AlphaFold 3 trunk: A 4-block MSA module, then 48 Pairformer blocks on single and pair representations (Abramson 2024). 5. Diffusion: Atom coordinates generated from noise; a confidence head predicts pLDDT, PAE and PDE (Abramson 2024).
What are the starting materials and the product?
Starting materials: Sequences (and for AlphaFold 3, ligands, ions and modified residues). Product: Atomic coordinates with confidence (pLDDT, PAE).
