# AnimeGen-T2V-A14B-Lightning-bf16 (MLX)

An **MLX (Apple Silicon)** conversion of [aidealab/AnimeGen-T2V](https://huggingface.co/aidealab/AnimeGen-T2V) — an
anime-specialized **full fine-tune of Wan2.2-T2V-A14B** (dual-expert MoE) — in **bf16**, shipped as a pre-merged
**Lightning** checkpoint for few-step, CFG-free inference.

Built for the Swift-MLX `wan-core` / Bernini-R runtime: the flat, 1095-key A14B checkpoint layout that runtime
loads. For lighter footprint see the [int4 variant](https://huggingface.co/mlx-community/AnimeGen-T2V-A14B-Lightning-int4).

## What's in here

| File | What |
|---|---|
| `high_noise_model.safetensors` | fine-tuned high-noise expert (bf16), Lightning-merged |
| `low_noise_model.safetensors` | fine-tuned low-noise expert (bf16), Lightning-merged |
| `vae.safetensors` | 16-channel Wan VAE (stock Wan2.2) |
| `t5_encoder.safetensors` | umT5-XXL text encoder (stock Wan2.2) |
| `config.json` | Wan2.2-A14B config |

## How it was made

1. The two fine-tuned experts from `aidealab/AnimeGen-T2V` (original-Wan key naming, bf16) were converted 1:1 into
   the MLX A14B layout (`sanitize_wan_transformer_weights`; key set asserted equal to the base A14B contract — 1095
   keys, 0 added / 0 dropped).
2. The [lightx2v Wan2.2-Lightning](https://huggingface.co/lightx2v/Wan2.2-Lightning)
   `Wan2.2-T2V-A14B-4steps-lora-250928` LoRA was **merged offline** per-expert with AIdeaLab's weighting
   (`set_adapters([high, low], [2.0, 1.0])`; kohya `W += strength·(alpha/rank)·(up @ down)`).

## Recommended inference recipe (from the AnimeGen model card)

- Sampler: **euler**, **CFG-free** (guidance 1.0)
- **8 steps**, **shift 3.0** (FlowMatchEuler)
- 832×480 or 1280×720, frames `16·seconds + 1` (must be 4n+1), 16 fps
