# Bernini-v2 (int4, MLX)

4-bit variant of [`mlx-community/Bernini-v2-bf16`](https://huggingface.co/mlx-community/Bernini-v2-bf16)
— Apple-MLX conversion of [ByteDance/Bernini-Diffusers-v2](https://huggingface.co/ByteDance/Bernini-Diffusers-v2)
(revision `399cf6a`, Apache-2.0).

**Quantization scope:** the two Wan2.2-A14B transformer experts only (attention + FFN Linears,
4-bit, group size 64; embeddings/norms/head/modulation stay bf16). The planner plane
(`mllm/`, `vit_decoder`, `planner_glue`), umT5 encoder, and VAE pass through at bf16 —
weight-only int4 on diffusion transformers costs measurable quality (bf16 is the recommended
default; this variant is the memory-constrained opt-in).

See the bf16 repo's card for the full component table, conversion notes, retrained-experts
warning (not interchangeable with `Bernini-R-*`), usage pointers, and provenance.
