Information
GPT4-X-Alpaca 30B 4-bit working with GPTQ versions used in Oobabooga's Text Generation Webui and KoboldAI.This was made using Chansung's GPT4-Alpaca Lora
Update 04.29.2023
Updated the ggml quantizations to be compatible with the latest version of llamacpp.
What's included
GPTQ: 2 quantized versions. One quantized --true-sequential and act-order optimizations, and the other was quantized using --true-sequential --groupsize 128 optimizations
GGML: 2 quantized versions. One quantized using q4_1, and the other was quantized using q5_0.
GPU/GPTQ Usage
To use with your GPU using GPTQ pick one of the .safetensors along with all of the .jsons and .model files.
Oobabooga: If you require further instruction, see here and here
KoboldAI: If you require further instruction, see here
CPU/GGML Usage
To use your CPU using GGML(Llamacpp) you only need the single .bin ggml file.

Benchmarks
--true-sequential --act-order
Wikitext2: 4.481280326843262
Ptb-New: 8.539161682128906
C4-New: 6.451964855194092
Note: This version does not use --groupsize 128, therefore evaluations are minimally higher. However, this version allows fitting the whole model at full context using only 24GB VRAM.
--true-sequential --groupsize 128
Wikitext2: 4.285132884979248
Ptb-New: 8.34856128692627
C4-New: 6.292652130126953
Note: This version uses --groupsize 128, resulting in better evaluations. However, it consumes more VRAM.
