Deep dive
Notes, sources, and the full write-up
Pi3X is an open-weight 3D generation model from yyfz233, published on Hugging Face in December 2025. It has 1.4B parameters and is released under the cc-by-nc-4.0 license.
HardwareLink to this section
At full FP16 precision the weights need about 3 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 Pi3X need?
Pi3X with 1.4B parameters needs approximately 1 GB at Q4_K_M quantization. Use our VRAM calculator for an exact estimate.
Is Pi3X better than other yyfz233 models?
Pi3X has 1.4B parameters with 8,192 context - a strong choice for 3d-generation.
What license is Pi3X under?
Pi3X is released under the cc-by-nc-4.0 license, making it suitable for most commercial and personal projects.
What hardware runs Pi3X well?
With 1.4B parameters, Pi3X 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 Pi3X?
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.
