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

MLX 8bit (affine, group size 64) quantized variant of LiquidAI/LFM2.5-8B-A1B (8B/1B-active mixture-of-experts) for Apple silicon via mlx-lm.

Provenance

Source: LiquidAI/LFM2.5-8B-A1B @ revision b9aebfcbe28b6cb374042f495d733037550ab146 (LFM Open License v1.0 — see LICENSE in this repo).
Quantized with mlx_lm.convert (mlx-lm 0.31.3): affine, 8-bit, group size 64.

Smoke gate

Before upload this pack passed a deterministic coherence gate: greedy 32-token chat generation loaded through mlx_lm.load, judged for emptiness, repetition loops, multi-script gibberish, and special-token debris. Verdict: ok.

Usage

pip install mlx-lm
mlx_lm.generate --model majentik/LFM2.5-8B-A1B-MLX-8bit --prompt "Hello"
