Liquid AI's LFM2.5-Embedding-350M is a text embedding model built on the LFM2.5-350M-Base checkpoint and, alongside LFM2.5-ColBERT-350M, one of the first bidirectional members of the LFM family. The maker describes it as a dense bi-encoder producing one vector per document for the smallest, fastest index and a drop-in replacement for RAG pipelines targeting fast, cheap, reliable multilingual search across 11 languages. It is built for short-context retrieval like e-commerce semantic search, support knowledge bases, on-device semantic search, and enterprise knowledge assistants.

Running locally
By our estimate, LFM2.5-Embedding-350M needs about 0.7 GB at Q4, 0.9 GB at Q8 and 1.3 GB at FP16 of VRAM. That covers the weights plus headroom for a short context, and longer contexts need more.
Yes, by our estimates LFM2.5-Embedding-350M fits on an 8 GB GPU at FP16 (about 1.3 GB) and at higher precision on larger cards.
Yes, a Mac with at least 8 GB of unified memory should run LFM2.5-Embedding-350M at Q4, which needs an estimated 0.7 GB. This assumes macOS gives the GPU about 75% of unified memory.
Privacy and data
Yes, LFM2.5-Embedding-350M has open weights, so you can run it on your own hardware and keep prompts on your own machines.
Capabilities and specs
LFM2.5-Embedding-350M has a 512 token context window. It can write up to 460 output tokens per response.
No, LFM2.5-Embedding-350M takes text input only.
