LFM3-1.7B model card and LFM Open License v1.0 (Liquid AI)

Summary

Liquid AI's Hugging Face card for LFM3-1.7B gives a 256K-token context (input plus output) and the licence: the LFM Open License v1.0. The licence is permissive (use, modify, redistribute, with a patent grant) but does not cover commercial use by entities with $10 million or more in annual revenue. The card gives no release date (the date above is the reading date).

Key points

• Licence terms: royalty-free, perpetual, and sublicensable, with Apache-style conditions (include the licence, mark changes, keep notices). Commercial use is licensed only below $10M annual revenue, counted across the whole corporate group. Qualified non-profits are exempt for non-commercial or research use. The patent licence ends if you sue over patents.
• Repos: LFM3-1.7B and -Base, LFM3-VL-2B, LFM3-Audio-2B, LFM3-Omni-2B, plus GGUF, NVFP4, FP8, and MLX variants.
• The family page shows no licence on the listing itself; the terms come from the LICENSE file in the LFM3-1.7B repo. Other LFM3 repos were not checked one by one.

Why it matters

LFM3 is free for individuals and small companies, but larger companies need a separate agreement, so it is not "open source" in the OSI sense. This matters when picking a small local model for a product.
