Wan2.2 T2V A14B — MLX

Apple-Silicon-native Q4 MLX packaging of Wan2.2 T2V A14B with dual high/low-noise experts, a bundled offline tokenizer, a shared T5/VAE, and a tested command-line runtime.

This is a community derivative assembled by PocketAI. It is not an official Wan-AI or SceneWorks release, and no endorsement is implied. PocketAI did not train the base model or perform the original SceneWorks conversion.

Available precision variants

Provenance

• Base model: Wan-AI/Wan2.2-T2V-A14B
• MLX conversion: SceneWorks/wan2.2-t2v-a14b-mlx
• Runtime: mlx-video
• PocketAI changes: MODIFICATIONS.md

Included files

Model data totals 26.68 GiB. The bundled runtime resolves the shared support models from common/ automatically.

Requirements

• Apple Silicon Mac
• Python 3.11, 3.12, or 3.13
• ffmpeg available on PATH
• Approximately 26.68 GiB disk space plus the Python environment and generated videos
• 24 GB unified memory for short low-guidance tests; 128 GB was used for the validated 81-frame CFG benchmark

Generate a five-second video

.venv/bin/pocketai-wan-video \
  --model-dir q4 \
  --prompt "A chestnut horse runs across a sunlit field, side tracking camera, photorealistic." \
  --width 512 --height 320 --num-frames 81 \
  --steps 10 --guide-scale 3,4 --scheduler unipc \
  --seed 42 --output-path horse.mp4

Wan uses 16 fps in this package. 81 frames encode to 5.0625 seconds. Frame counts must follow 4n+1, and width/height should be divisible by 32.

PocketAI benchmark

Apple M5 Max, 128 GB unified memory; identical prompt and seed; 512×320, 81 frames, 16 fps, 10 UniPC steps, guidance 3/4:

Q4 is the recommended default. Q8 is the higher-detail option. BF16 is included for experimentation and maximum numerical precision, not because one test establishes it as perceptually better.

Watch the synchronized comparison. Machine-readable measurements are in benchmark/metrics.json.

Limitations

• Wan2.2 A14B is large and slow. A separate 768×512 Q4 reference took 36:53 end to end on the test machine.
• Same-seed outputs can diverge across precisions; divergence is not itself a quality ranking.
• This release has not been validated on Intel Macs, iOS, or machines with less memory.
• Ten UniPC steps are a speed-oriented setting. More steps can improve results at substantial additional cost.
• Review the Apache-2.0 license and applicable laws before use.
