Liquid AI’s LFM2.5-Encoder line introduces two multilingual bidirectional encoders: 230M and 350M parameters.

The models are built for fine-tuning on classification, token labeling, retrieval, reranking, semantic similarity, NLI, and extractive QA across 15 languages. The release emphasizes long context and efficiency: both variants support 8k context, run well on-device, and can even execute in the browser on WebGPU. The attached benchmark shows the 350M model scoring 81.02 on a 17-task fine-tuning benchmark, ahead of the 230M variant at 79.29 and competitive with larger encoders.
