Practical guide: Recommended quantization for various AI models
Memestonks2020 · reddit · 2026-08-18
An experienced model user shared recommendations for quantizing different types of AI models:
- LLMs: Q8 offers the best balance between quality and speed.
- Video Generation: Q8 works fine; lower quantization introduces artifacts.
- Image Generation: Q8 is best to maintain high quality.
- Vision-Language (VL) Models: Q4 is best due to VRAM ballooning at high resolutions.
- General Audio Generation: Q8 is preferred; Q4 causes major sound quality degradation.
- Music Generation: BF16 or FP16 are required, as quality drops significantly even with Q8.
