Quants for Sao10K's model WinterGoddess 1.4 70b : https://huggingface.co/Sao10K/WinterGoddess-1.4x-70B-L2

The model has been tweaked with limarvp3 and a Linear Rope 8 training to go to 32k context (with even better results in rope 4 and rope 2, maybe other lesser ropes as well)

I don't know who did the job, only that I found this quant hanging around without FP16 : https://huggingface.co/mishima/WinterGoddess-1.4x-limarpv3-70B-L2-32k.GGUF

So I made a Q8_0 out of it (best way to requantize after), and requantized it in Q3_K_S and Q2_K for my need.

Lowers quants (SOTA 2 bits) to come if I'm able to make an iMatrix on my config (64GB RAM).

-----

Edit : Due to a poor CPU (i7-6700k) for AI purpose, and only 36GB of VRAM, I remade Q3_K_S and Q2_K with an small iMatrix of ctx 32 with 25 chunks (so, 640 tokens), and it lowers the perplexity by :

More than 3% in Rope 8 on Q2_K
