Instruction-Tuned Mamba 2.8B on SlimOrca Dataset

Overview

This repository features the 2.8 billion parameter Mamba model, fine-tuned on a subset (20k) of the SlimOrca dataset. Big thanks to Justin Mattern from Haven for contributing essential code in the mamba-chat repository

Usage Instructions

To utilize the fine-tuned model, follow the Python code snippet below:

import torch
from transformers import AutoTokenizer
from mamba_ssm.models.mixer_seq_simple import MambaLMHeadModel

device = "cuda"
tokenizer = AutoTokenizer.from_pretrained("Schmadge/mamba-slim-orca")
tokenizer.eos_token = tokenizer.pad_token = "<|endoftext|>"
tokenizer.chat_template = AutoTokenizer.from_pretrained("HuggingFaceH4/zephyr-7b-beta").chat_template
model = MambaLMHeadModel.from_pretrained("Schmadge/mamba-slim-orca", device=device, dtype=torch.float16)

def generate_response(system_prompt, user_prompt):
    # Preparing the prompt
    prompt = [
        {"role": "system", "content": system_prompt},
        {"role": "user", "content": user_prompt}
    ]
    input_ids = tokenizer.apply_chat_template(prompt, return_tensors="pt", add_generation_prompt=True).to(device)

    # Generating the response
    out = model.generate(input_ids=input_ids, max_length=2000, temperature=0.3, top_p=0.7, eos_token_id=tokenizer.eos_token_id)
    decoded = tokenizer.batch_decode(out)

    return decoded[0].split("<|assistant|>\n")[-1].replace('<|endoftext|>','')

system_prompt = "You are an AI assistant. Provide a detailed answer so user don't need to search outside to understand the answer."
user_prompt = "In a room I have only 3 sisters. Anna is reading a book. Alice is playing a match of chess.What the third sister, Amanda is doing ?"
response = generate_response(system_prompt, user_prompt)
print(response)
#Based on the information provided, we can infer that Amanda is playing a match of chess with Alice. Since Anna is reading a book, it is reasonable to assume that Amanda is playing a game of chess with Alice, as this is a common activity for siblings to engage in together.
