LFM2 (Liquid Foundation Models 2)

model
Liquid AI

Efficient foundation models using a hybrid backbone combining gated short convolutions with grouped query attention. 350M to 24B parameters (MoE, 2.3B active). Optimized for edge and on-device deployment.

LFM2-24B achieves 239 tok/s (#3 speed ranking on AA). Also includes vision-language (LFM2-VL), speech (LFM2-Audio), and pharmaceutical variants (with Insilico Medicine). AA Intelligence Index v4.3: 6 (24B). Apache 2.0. Succeeded in 2026 by the continued-pretraining LFM2.5 series.
