AnimeGen-T2V-A14B-Lightning-bf16 (MLX)
An MLX (Apple Silicon) conversion of 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.

How it was made
- 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). - The lightx2v Wan2.2-Lightning
Wan2.2-T2V-A14B-4steps-lora-250928LoRA was merged offline per-expert with AIdeaLab's weighting (set_adapters([high, low], [2.0, 1.0]); kohyaW += 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
