## AI overview

Anthropic reported that Claude optimized 36 packages covering more than 30 open-source biomolecular models across six model families in under four weeks. The optimized implementations offer Exact, Fast, and Big modes, with reported speed and memory benefits. Anthropic also open-sourced the code and introduced FlashPairformer, custom CUDA kernels for protein-structure workloads.

## Source excerpt

Anthropic published a research post on September 17, 2026, reporting that Claude optimized more than 30 open-source biomolecular models in just under four weeks, which the company said sped the models up roughly 4x on average. Anthropic open-sourced the optimized code and announced a protein design competition co-sponsored with Adaptyv Bio. 36 Optimized Packages and FlashPairformer Kernels According to the research post and an accompanying technical report, an internal general-purpose research...
