# Bernini — MLX (full planner + renderer)

Native **Apple Silicon / MLX** conversion of ByteDance **Bernini** (the full pipeline), packaged for
in-process generation in [SceneWorks](https://github.com/michaeltrefry). Bernini is a
**Latent Semantic Planning** model: a Qwen2.5-VL-7B semantic planner (MAR loop) drives a
**Wan2.2-T2V-A14B** dual-expert renderer.

This is a turnkey, self-contained snapshot — no diffusers source or separate Wan base is needed at
runtime. It loads directly via `mlx_gen::load("bernini")` (mlx-gen-bernini) and is quantized to
**Q4 (default) / Q8 (opt-in)** at load time.

## Contents
- `qwen2_5_vl.safetensors` + `qwen2_5_vl_config.json` — Qwen2.5-VL-7B planner backbone + vision tower
- `connector.safetensors`, `vit_decoder.safetensors`, `mask_tokens.safetensors` — MLP connector, ViT
  decoder (clip-diff flow head), MAR mask token
- `high_noise_model.safetensors` + `low_noise_model.safetensors` — the Wan2.2 dual-expert renderer DiTs
- `t5_encoder.safetensors` + `tokenizer.json` — UMT5-XXL text encoder + tokenizer
- `vae.safetensors` — z16 AutoencoderKLWan
- `mllm/` — Qwen ChatML tokenizer/config; `*.json` sidecars — config + planner/renderer knobs

`dtype`: bf16. Validated on a 128 GB Apple Silicon Mac for **text-to-image** and **text-to-video**
(~44 GB peak at Q4).
