Wizard Mega 13B GGML

This is GGML format quantised 4bit and 5bit models of OpenAccess AI Collective's Wizard Mega 13B.

This repo is the result of quantising to 4bit and 5bit GGML for CPU inference using llama.cpp.

Repositories available

THE FILES IN MAIN BRANCH REQUIRES LATEST LLAMA.CPP (May 12th 2023 - commit b9fd7ee)!

llama.cpp recently made a breaking change to its quantisation methods.

I have quantised the GGML files in this repo with the latest version. Therefore you will require llama.cpp compiled on May 12th or later (commit b9fd7ee or later) to use them.

As of May 15th, text-generation-webui is now updated for the new GGML formats, so if you have problems loading these files in that UI, please update it to the latest version.

Provided files

Name	Quant method	Bits	Size	RAM required	Use case
`wizard-mega-13B.ggml.q4_0.bin`	q4_0	4bit	8.14GB	10.5GB	4-bit.
`wizard-mega-13B.ggml.q4_1.bin`	q5_0	5bit	8.95GB	11.0GB	5-bit. Higher accuracy, higher resource usage and slower inference.
`wizard-mega-13B.ggml.q5_0.bin`	q5_1	5bit	9.76GB	12.25GB	5-bit. Even higher accuracy, and higher resource usage and slower inference.
`wizard-mega-13B.ggml.q8_0.bin`	q8_0	8bit	14.6GB	17GB	8-bit. Almost indistinguishable from float16. Huge resource use and slow. Not recommended for normal use.

How to run in `llama.cpp`

I use the following command line; adjust for your tastes and needs:

./main -t 8 -m wizard-mega-13B.ggml.q5_0.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "### Instruction: write a story about llamas ### Response:"

Change -t 8 to the number of physical CPU cores you have.

How to run in `text-generation-webui`

GGML models can be loaded into text-generation-webui by installing the llama.cpp module, then placing the ggml model file in a model folder as usual.

Further instructions here: text-generation-webui/docs/llama.cpp-models.md.

Original Wizard Mega 13B model card

Wizard Mega is a Llama 13B model fine-tuned on the ShareGPT, WizardLM, and Wizard-Vicuna datasets. These particular datasets have all been filtered to remove responses where the model responds with "As an AI language model...", etc or when the model refuses to respond.

Release (Epoch Two)

The Wizard Mega 13B SFT model is being released after two epochs as the eval loss increased during the 3rd (final planned epoch). Because of this, we have preliminarily decided to use the epoch 2 checkpoint as the final release candidate. https://wandb.ai/wing-lian/vicuna-13b/runs/5uebgm49

Build

Wizard Mega was built with Axolotl on 8xA100 80GB for 15 hours. The configuration to duplicate this build is provided in this repo's /config folder.

Examples

### Instruction: write Python code that returns the first n numbers of the Fibonacci sequence using memoization.

### Assistant: 
```python
def fib(n):
    if n < 2:
        return n
    elif n in cache:
        return cache[n]
    else:
        a, b = 0, 1
        for i in range(2, n+1):
            cache[i] = a
            a, b = b, a + b
        return cache[n]
    
def first_n(n):
    fib_list = [fib(i) for i in range(n+1)]
    return fib_list[:n]
```
This function uses memoization to store the values of previous Fibonacci numbers in a cache. This way, if the same number is requested again, it can be returned immediately without recalculating it. 
The `first_n` function takes an integer `n` as input, and calculates the first n numbers of the Fibonacci sequence using memoization. It returns a list of those numbers.

### Instruction: Finish the joke, a mechanic and a car salesman walk into a bar...  

### Assistant:  ...and the bartender says "Hey guys, what can I get for you?" The mechanic replies, "I'll have a beer, but make it a quick one. I have to fix this guy's car before he finds out I
 fiddled with his brakes." The salesman quips, "And I'll have a martini, shaken not stirred. After all, I have to sell this guy a car that doesn't break down on him within the first year of ownership."
