Summary

Liquid AI released LFM2-1.2B-Longevity and LFM2-2.6B-Longevity, small models built to interpret structured aging data. They cover several data types: clinical records, DNA methylation, transcriptomics, proteomics and genetics. The release is a good example of small, domain-specialized models.

Key points

• Two sizes were released: LFM2-1.2B-Longevity and LFM2-2.6B-Longevity.
• They are specialized for interpreting structured aging data across different data types.
• Clinical records come from NHANES.
• DNA methylation data comes from GEO.
• Transcriptomics data comes from GTEx.
• Proteomics data comes from Olink; genetic data is also covered.
