What is eight-bit artificial intelligence model quantization?
Definition
Eight-bit artificial intelligence model quantization, often labeled Q8, represents model values with more precision than Q4 while still using less memory than common higher-precision formats. The extra detail can improve consistency on demanding tasks.
Q8 requires more memory and can add latency compared with Q4. It is useful when output quality and reliable requirement-following matter more than fitting the smallest possible hardware footprint.

Frequently asked questions
What does Q8 mean for an AI model?
Q8 usually refers to a model quantized to about eight bits per stored weight, although exact formats and scaling methods vary.
Why choose Q8 instead of Q4?
Q8 can preserve more numerical information and improve consistency when the available memory and acceptable latency allow it.
