Faisal Bin Ashraf and co-authors (arXiv v1, March 4, 2026) introduce Ab-Affinity, a large language model that predicts antibody binding affinity to target peptides such as the SARS-CoV-2 spike protein. The paper reports improved prediction accuracy using extensive experimental antibody data and AI methods, and releases code and model weights in a public repository. The approach supports faster design of neutralizing antibodies.
Key Points
- 1Introduces Ab-Affinity LLM that predicts antibody-peptide binding affinity, validated on SARS-CoV-2 spike datasets.
- 2Leverages exponential growth in experimental antibody data and AI architectures to improve prediction accuracy.
- 3Provides open-source code and models enabling practitioners to accelerate neutralizing-antibody design and validation.
Scoring Rationale
Open-source, directly usable LLM advances antibody-affinity prediction; limited by single-source arXiv preprint and limited peer validation.
