LFM2.5-8B-A1B-MLX-4bit

LFM2.5-8B-A1B-MLX-4bit — availability mirror

A verbatim mirror of LiquidAI/LFM2.5-8B-A1B-MLX-4bit. 4-bit quantized. The default variant our packages register.

Why this repo exists

We ship Swift/MLX packages that name a weight repo in code. When an upstream repo moves or disappears, every already-published version of those packages breaks for anyone installing fresh — there is no redirect and no way to patch software already in someone's hands.

That is not hypothetical: an unrelated model family we had ported was reorganized onto a new HuggingFace org without redirects, and six of our published packages broke the same day. This mirror exists so that the same failure cannot take LFM2.5 with it.

It exists for durability, not improvement. Nothing here is changed, tuned, or repackaged, and LiquidAI's original is the better place to get these weights if you want the newest revision. All model IP, training, and quantization are LiquidAI's work.

Integrity

Byte-for-byte identical to upstream. Every file was verified by SHA-256 against the corresponding LiquidAI/LFM2.5-8B-A1B-MLX-4bit file immediately before upload, and the published copies were re-verified afterward. The hashes are listed below so the claim is checkable rather than merely asserted:

Small non-LFS files (configs, tokenizer metadata) carry no upstream hash to compare against and were verified by exact byte size.

Licence — the commercial threshold matters

These weights are governed by the LFM Open License v1.0, included in full as LICENSE. Mirroring changes nothing about it.

It is Apache-2.0-shaped, with one condition that is easy to miss and important if you are building a product rather than experimenting:

Section 5 — Commercial Use limitation. Commercial use by a legal entity with annual revenue at or above $10,000,000 USD is not licensed under this agreement. Below that threshold, commercial use is permitted. Qualified non-profits are exempt for non-commercial and research purposes.

Redistribution is expressly permitted by §4, on four conditions: supply a copy of the licence, mark any files you modified, retain attribution notices, and carry forward any NOTICE file. We have modified nothing.

This summary is a pointer, not a substitute for reading the licence, and where the two differ the licence governs.

Credit

LFM2.5-8B-A1B is designed, trained, quantized, and released by LiquidAI. This mirror adds nothing but an address we can promise not to move.
