Brief

LiquidAI released two 350M-parameter multilingual retrieval models on 2026-06-18: LFM2.5-Embedding-350M (a bi-encoder) and LFM2.5-ColBERT-350M (a multi-vector ColBERT with late interaction). Both support 11 languages — Arabic, German, English, Spanish, French, Italian, Japanese, Korean, Norwegian, Portuguese, and Swedish — and mark the LFM family's first bidirectional models.

Why it matters

LiquidAI released two multilingual retrieval models on 2026-06-18: LFM2.5-Embedding-350M and LFM2.5-ColBERT-350M.

Key details

  • Both models are 350M-parameter, cover 11 languages (ar, de, en, es, fr, it, ja, ko, no, pt, sv), and are the first bidirectional members of the LFM family.
  • LFM2.5-Embedding-350M is a bi-encoder; LFM2.5-ColBERT-350M is a multi-vector ColBERT-style model using late interaction.
