Real-World Examples

“And it offers different “quantizations” (basically, trading a little precision for a smaller size) that help it span Macs with different amounts of RAM.”

“One of the most widely used techniques to make AI models more efficient, quantization, has limits — and the industry could be fast approaching them.”
TechCrunch · 23 Dec 2024
“To get around this, you can either split that model up across multiple chips - or even servers - or you can compress the model weights to a lower precision in a process called quantization.”
