LFM3-1.7B

LFM3-1.7B is the text model of LFM3, the third generation of Liquid Foundation Models that Liquid AI announced on 27 October 2026. The first LFM3 release covers six models in the 2-billion-parameter class, for text, vision, audio, omni and decision tasks, all trained from one shared base, LFM3-1.7B-Base. Base and post-trained weights are open on Hugging Face, and the models are also offered in Liquid's Playground and through the Liquid AI API.

## What it does

Liquid AI builds small models meant to run on the device where an application lives. LFM3 uses a new tri-hybrid architecture, redesigned with the company's hardware-in-the-loop architecture search for agentic use and fast inference over long contexts, and was pre-trained on 22 trillion tokens. Liquid AI says LFM3-1.7B outperforms its previous LFM2.5-2.6B while using 35 percent fewer parameters.

The text model has a 256K-token context window and fits in about 1 GB at 4-bit precision. Its Hugging Face card lists English, Arabic, Chinese, French, German, Italian, Japanese, Korean, Portuguese, Spanish, Vietnamese, Thai, Indonesian, Hindi, Russian and Polish.

## Who it is for

The model is meant as a starting point for specialised models: Liquid AI says every LFM3 model can be fine-tuned on a single GPU and deployed where the application runs, which suits teams building on-device assistants, offline tools or narrow agents that cannot send data to a hosted model. The weights are released under the LFM Open License v1.0, which has its own commercial-use terms that a business should read before deployment.
