BigBang-v1-MLX-MXFP4

MLX MXFP4 (mxfp4, group size 32) quantized variant of endless-frontier/BigBang-v1 (text tower quantized; vision tower and projector retained in BF16) for Apple silicon via mlx-lm.

Provenance

Source: endless-frontier/BigBang-v1 @ revision fe313c9057ca2c51a07c7cf141915dc8cc3f620e (Apache-2.0 (upstream LICENSE)).
Quantized with mlx_lm.convert (mlx-lm 0.31.3): mxfp4, 4-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/BigBang-v1-MLX-MXFP4 --prompt "Hello"
