Quantised GGMLs of alpaca-lora-65B
Quantised 4bit and 5bit GGMLs of changsung's alpaca-lora-65B for CPU inference with llama.cpp.
I also have 4bit GPTQ files for GPU inference available here: TheBloke/alpaca-lora-65B-GPTQ-4bit.
REQUIRES LATEST LLAMA.CPP (May 12th 2023 - commit b9fd7ee)!
llama.cpp recently made a breaking change to its quantisation methods.
I have re-quantised the GGML files in this repo. Therefore you will require llama.cpp compiled on May 12th or later (commit b9fd7ee or later) to use them.
The previous files, which will still work in older versions of llama.cpp, can be found in branch previous_llama.
Provided files
| Name | Quant method | Bits | Size | RAM required | Use case |
|---|---|---|---|---|---|
alpaca-lora-65B.ggml.q4_0.bin |
q4_0 | 4bit | 40.8GB | 43GB | 4bit. |
alpaca-lora-65B.ggml.q5_0.bin |
q5_0 | 5bit | 44.9GB | 47GB | 5bit. Higher quality than 4bit, at cost of slightly higher resources. |
alpaca-lora-65B.ggml.q5_1.bin |
q5_1 | 5bit | 49GB | 51GB | Sbit. Slightly higher resource usage and quality than q5_0. |
- The q4_0 file provides lower quality, but maximal compatibility. It will work with past and future versions of llama.cpp
- The q5_0 file is using brand new 5bit method released 26th April. This is the 5bit equivalent of q4_0.
- The q5_1 file is using brand new 5bit method released 26th April. This is the 5bit equivalent of q4_1.
How to run in llama.cpp
I use the following command line; adjust for your tastes and needs:
./main -t 18 -m alpaca-lora-65B.ggml.q4_0.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "Below is an instruction that describes a task. Write a response that appropriately completes the request.
### Instruction:
Write a story about llamas
### Response:"
Change -t 18 to the number of physical CPU cores you have. For example if your system has 8 cores/16 threads, use -t 8.
If you want to have a chat-style conversation, replace the -p <PROMPT> argument with -i -ins
How to run in text-generation-webui
Further instructions here: text-generation-webui/docs/llama.cpp-models.md.
Note: at this time text-generation-webui will not support the new q5 quantisation methods.
Thireus has written a great guide on how to update it to the latest llama.cpp code so that these files can be used in the UI.
Original model card not provided
No model card was provided in changsung's original repository.
Based on the name, I assume this is the result of fine tuning using the original GPT 3.5 Alpaca dataset. It is unknown as to whether the original Stanford data was used, or the cleaned tloen/alpaca-lora variant.
