Ornith-1.5-35B-A3B-MLX-3bit

MLX 3bit (affine, group size 32) quantized variant of ornith-ai/Ornith-1.5-35B-A3B (text tower quantized; vision tower and projector retained in BF16) for Apple silicon via mlx-lm.

Provenance

Source: ornith-ai/Ornith-1.5-35B-A3B @ revision e4dfb35a93d4b6822a811a7676f3488514abe7e2 (MIT (upstream LICENSE)).
Quantized with mlx_lm.convert (mlx-lm 0.31.3): affine, 3-bit, group size 32.

Smoke gate

Before upload this pack passed a deterministic coherence gate: greedy 48-token chat generation loaded through mlx_lm.load, judged for emptiness, repetition loops, multi-script gibberish, and special-token debris. Verdict: ok.

Usage

bash

pip install mlx-lm
mlx_lm.generate --model majentik/Ornith-1.5-35B-A3B-MLX-3bit --prompt "Hello"

First-party tiers

ornith-ai publishes first-party 4bit/6bit/8bit MLX and GGUF packs for this model. The tiers in this family (2bit, 3bit, 5bit, MXFP4) complement those first-party releases rather than duplicating them.
