Orca_alpaca_3b

An Open_LLaMA-3B model trained on explain tuned datasets, created using Instructions and Input from Alpaca datasets and applying Orca Research Paper dataset construction approaches.

Dataset

We build explain tuned Alpaca dataset ~52K created using approaches from Orca Research Paper.

We leverage all of the 15 system instructions provided in Orca Research Paper. to generate custom datasets, in contrast to vanilla instruction tuning approaches used by original datasets.

This helps student model aka this model to learn thought process from teacher model, which is ChatGPT (gpt-3.5-turbo-0301 version).

Please see below example usage how the System prompt is added before each instruction.

Training

The training configurations are provided in the table below.

The training takes on 4x A600(50G) GPUs and lasts for around 20 Hours for cost of $66 using Lambda Labs

We used DeepSpeed with Zero-3 approaches for parallel gpu training by writing our own fine tunning scripts plus leveraging some of the model training code provided by amazing OpenAlpaca repo

Here are some of params used during training:

batch_size	16
train_micro_batch_size_per_gpu	2
gradient_accumulation_steps	2
Learning rate	2e-5
Max length	1024
Epochs	3

Example Usage

Below shows an example on how to use alpaca_orca_open_llama_3b

import torch
from transformers import LlamaForCausalLM, LlamaTokenizer

# change model_path between 3b,7b or 13b
model_path = 'psmathur/alpaca_orca_open_llama_3b'
tokenizer = LlamaTokenizer.from_pretrained(model_path)
model = LlamaForCausalLM.from_pretrained(
    model_path, torch_dtype=torch.float16, device_map='auto',
)


#generate text function
def generate_text(system, instruction, input=None):
    
    if input:
        prompt = f"### System:\n{system}\n\n#\n\n### User:\n{instruction}\n\n### Input:\n{input}\n\n### Response:\n"
    else:
        prompt = f"### System:\n{system}\n\n#\n\n### User:\n{instruction}\n\n### Response:\n"
    
    tokens = tokenizer.encode(prompt)
    tokens = torch.LongTensor(tokens).unsqueeze(0)
    tokens = tokens.to('cuda')

    instance = {'input_ids': tokens,'top_p': 1.0, 'temperature':0.7, 'generate_len': 1024}

    length = len(tokens[0])
    with torch.no_grad():
        rest = model.generate(
            input_ids=tokens, 
            max_length=length+instance['generate_len'], 
            use_cache=True, 
            do_sample=True, 
            top_p=instance['top_p'],
            temperature=instance['temperature']
        )    
    output = rest[0][length:]
    string = tokenizer.decode(output, skip_special_tokens=True)
    print(f'[!] Response: {string}')

# same prompt as provided by Orca Research Paper
system = 'You are an AI assistant. User will you give you a task. Your goal is to complete the task as faithfully as you can. While performing the task think step-by-step and justify your steps.'
instruction = 'Use the given data to calculate the median.'
input = '[5,2,3,4,1]'
generate_text(system, instruction, input)

Next Goals:

1. Try more data, Dolly V2, WizardLM, & Others (we are open for suggestions)
2. Try bigger OpenLLaMA models 7B and 13B
3. Try better GPU for training, couldn't get 8xA100 (40GB), I guess they are in hot demand now.
4. Provide more options for Text generation UI. (may be https://github.com/oobabooga/text-generation-webui)
5. Provide 4bit GGML/GPTQ quantized model (may be TheBloke can help here)
