This is a Floating Point 32 upscale, where all components and merges were remastered to floating point 32. This includes all the merges (recreated with master files), and where possible subbing full FP32 models.
This repo contains the new Imatrix Plus 2 quants using a new inhouse dataset merged with a master dataset to push performance of the Ultra Quality remaster even higher.
The goal: Carry forward maximum precision right up to the point where it is "GUFFed".
This includes F32 master file for GGUF too... at a whopping 78 GBs.
WHY?
Because the difference between F32 vs BF16 is... over 8 DECIMAL places.
And as each merge / model is modified there are "losses" along the way.
These losses are carried forward and in turn lead to more losses.
And decimal points are critical to model performance.
SMALL?
Yes... but multiplied by each merge(s), and compression(s): 20 billion times.
The result:
At Q2K an impressive drop of 533 points in perplexity. (lower is better) (VS: Q2K original base model: PPL = 9.8077 +/- 0.06821 )
At Q4KM a whopping drop of 976 points in perplexity. (VS: Q4km original base model -> PPL = 8.7858 +/- 0.06074)
At Q6 an awesome drop of 234 points in perplexity. (VS: Q6 original base model -> PPL = 8.6070 +/- 0.05907 )
To put this in perspective "Q6" now operates ABOVE the original full precision version of "Psyonic-Cetacean-20b" and Q4KM operates at close to Q6 level quality.
This because at "Q6" the quant / compressed model is considered to be accurate within "+0.0008 ppl" of the full, uncompressed / unquanted model and it exceeds this threshold by over 200 points.
Imatrix quants take this even further in most cases DOUBLING the "drop" in perplexity realized in the reg quants.
Q4km-imatrix :
Final estimate: PPL = 8.6095 +/- 0.05898
(Non imatrix: Final estimate: PPL = 8.6902 +/- 0.05985 )
(VS: Q4km base model -> PPL = 8.7858 +/- 0.06074)
(VS: Q6 BASE model -> Final estimate: PPL = 8.6070 +/- 0.05907 Q6)
But... what about Q8?
The mountain moved:
150 points better: PPL = 8.5850 +/- 0.05881 VS: BASE/ORGINAL: PPL = 8.6012 +/- 0.05900
THE RESULTS ARE IN:
AS per Jeb Carter, original creator of the model:
- instruction following has improved dramatically.
- new abilities have emerged.
- he had to REDUCE the instructions sets used because the model no longer needed as specific instructions.
- prose, nuance and depth have all improved.
- known issues with the original model have disappeared.
This is not "something for nothing" ; it is method of ensuring maximum precision at every step just before "ggufing" the model.
The methods employed only ensure precision loss is minimized or eliminated.
It is mathematical and theory sound.
The bottom line here is this:
Higher quality instruction following and output.
Likewise you can use a smaller compression, with higher token per second and still get great quality.
Same great model... turbo charged.
This is the first group of remasters.
Thanks again to Jeb Carter, the original creator of "Psyonic-Cetacean 20B"
