GoKawiilWestlake lab open-sources Pinal, a natural-language protein design model
Researchers released Pinal, a system that designs functional proteins from natural-language descriptions, under an Apache 2.0 license, with code on GitHub and a public web server. The team withheld full release of its large-scale training corpus and pipeline, citing biosecurity concerns, while publishing inference code, evaluation code, model weights and usage instructions instead. The training data came from AFDB, which excludes viral proteomes, so the developers say Pinal was not built for viral protein design.
