Consensus Brief

Hugging Face has released draft model checkpoints for three models in the LFM2.5 family, which include LFM2.5-1.2B-Instruct, LFM2.5-2.6B, and LFM2.5-8B-A1B. These models utilize a new speculative decoding method called DSpark, resulting in significant improvements in inference speed without compromising output quality.
