This is a quantization function. It's a fairly "math brained" name I agree, but the function is called qX_K_q8_K
because it quantizes a value with a quantization index of X (unknown) to one with a quantization index of 8 (bits) which correlates to the memory usage. The 0
vs K
portions are how it does rounding, 0
means it does rounding by equal distribution (without offset), and K
means it creates a distribution that is more fine grained around more common values and is more rough around least common values. e.g. I have a data set that has a lot of values between 4 and 5 but not a lot of 10s. I have lets say 10 brackets between 4 and 5 but only 3 between 5 and 10.
Basically it's a lossy compression for a data set into a specific enumeration (roughly correlates with size), so it's a way to given 1,000,000 numbers from 1-1000000, of putting their values into a range of numbers based on the q level How using different functions affects the output of models is more voodoo than anything else. You get better "quality" output from higher memory space, but quality is a complex metric and doesn't necessarily map to factual accuracy in the output, just statistical correlation with the model's data set.
An example of a common quantizer is an analog to digital converter. It must take continuous values from a wave that goes 0 to 1 and transform them into digital values of 0 and 1 with a specific sample rate.
Taking a 32 bit float and copying the value into 32 bit float is an identity quantizer.
I've never said that AI is the cause of those problems that's words you're putting in my mouth. I've said that AI is being used as a solution to those problems in the industry when in reality the use of AI to solve those problems exacerbates them while allowing companies to reap "productive" output.
For some reason programmers can understand "AI Slop" but if the AI is generating code instead of stories, images, audio and video it's no longer "AI Slop" because we're exalted in our communion with the machine spirits! Our holy logical languages could never encode the heresy of slop!
