Deep dive
Notes, sources, and the full write-up
Pi3 is an open-weight 3D generation model from yyfz233, published on Hugging Face in July 2025. It has 960M parameters and is released under the bsd-2-clause license.
HardwareLink to this section
At full FP16 precision the weights need about 2 GB of memory; 8-bit quantization brings that to roughly 1 GB. That is small enough for most consumer GPUs, Apple Silicon Macs, and many CPUs.

Frequently asked
Quick answers to common questions
How much VRAM does Pi3 need?
Pi3 with 0.96B parameters needs approximately 1 GB at Q4_K_M quantization. Use our VRAM calculator for an exact estimate.
Is Pi3 better than other yyfz233 models?
Pi3 has 0.96B parameters with 8,192 context - a strong choice for 3d-generation.
What license is Pi3 under?
Pi3 is released under the bsd-2-clause license, making it suitable for most commercial and personal projects.
What hardware runs Pi3 well?
With 0.96B parameters, Pi3 requires adequate VRAM. High-end GPUs like the RTX 4090 (24GB), RTX 5090 (32GB), or Mac Studio with unified memory are good options. Check our hardware directory for specific recommendations.
What is the best quantization for Pi3?
Q4_K_M is the recommended sweet spot - ~98% of FP16 quality at ~27% of the size. Q5_K_M (~1 GB) is an option if you have spare VRAM. Use our VRAM calculator to compare.
