AlphaFold
Hacker ApprovedProtein structure predictor in AI tools
Recommended for predicting protein structures from sequence, with a large free database of folds; critics note predictions are estimates that still need validation and fail outside known structures.

Physics built into network architecture
“Physical models are baked right into AlphaFold models and development at multiple steps, it is a highly unique architecture and approach.”
Comment from 15 Dec 2025 in “Why proteins fold and how GPUs help us fold” “Physical insights are built into the network structure, not just a process around it”

What people warn about
Each mark is one comment
Predictions still need experimental validation
“you still have to validate the structures it estimates, which minimises any speed gains”
Comment from 16 Apr 2026 in “The Future of Everything Is Lies, I Guess: Where Do We Go from Here?” “what it outputs is a fundamentally a prediction with important limitations”
Comment from 16 Jan 2026 in “SETI Home Flags 100 Signals After Sorting 12B Others” “in practice not even alpha fold can tell me if my gfp fusion will work”
Comment from 8 Sep 2026 in “AlphaGenome Atlas predictive map of every DNA letter change in the human genome” Poor on out-of-sample proteins
“these folding models fail when we don't have crystal structures, so they are certainly not generalizing”
Comment from 18 Aug 2026 in “Amodei Re. Regulation” “AlphaFold is effectively blind, it was just trained on correctly folded proteins with known structure.”
Comment from 2 Jan 2026 in “Reality crushed Ÿnsect startup that had raised over $600M for insect farming” “it did far less for out of sample domains and it provides no intel into the kinetics of folding”
Comment from 14 Sep 2026 in “For AI leaders Doom is a form of hype” Did not truly solve folding
“Alphafold2 was great but didn't actually 'solve' protein-folding”
Comment from 7 Jun 2026 in “Biohub releases a world model of protein biology” “it had little to do with the problem as it's been understood to mean”
Comment from 29 Jul 2026 in “Google shuts down Nobel Prize winning AlphaFold” Ignores physics and folding kinetics
“it did far less for out of sample domains and it provides no intel into the kinetics of folding”
Comment from 14 Sep 2026 in “For AI leaders Doom is a form of hype” “it is optimizing for "looking like a protein", not for "obeying physics"”
