With 14B parameters, the cross-attention layers (which connect text to pixels) are deep and rich. The model handles complex compound prompts:

Temporal Coherence

• Data Format: In deep learning, FP16 is a standard format that uses half the memory of the traditional FP32 (32-bit) format.
• Implication for Users:

  Can you quantize it?

  Yes. Community members have created GGUF (quantized) versions of the Wan2.1 14B model. A Q4_K_M quant might reduce VRAM usage to ~14-16GB, but this will degrade the 720p quality, introducing compression artifacts and reducing temporal stability. The FP16 version remains the "gold standard."
