In an era where natural language processing is becoming increasingly vital, the release of FuseLLM-7B marks a significant advancement in the fusion of multiple large language models (LLMs). This tutorial will guide you through the setup, usage, and evaluation of this remarkable model.

Overview of FuseLLM

FuseLLM leverages the knowledge and strengths of various LLMs—specifically Llama-2-7B, OpenLLaMA-7B, and MPT-7B—to create a more powerful and flexible model. Unlike traditional ensemble models, FuseLLM uniquely combines diverse architectures to enhance overall performance.

Getting Started with FuseLLM-7B

To begin using FuseLLM, follow these simple steps:

1. Setup

• Ensure you have Python 3.9 installed.
• Install the necessary libraries by using:

pip install -r requirements.txt

2. Using FuseLLM-7B

Here’s a straightforward usage example:

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Wanfq/FuseLLM-7B", use_fast=False)
model = AutoModelForCausalLM.from_pretrained("Wanfq/FuseLLM-7B", torch_dtype="auto")
model.cuda()

inputs = tokenizer("your text here", return_tensors="pt").to(model.device)
tokens = model.generate(
    inputs,
    max_new_tokens=512,
    temperature=0.6,
    top_p=0.9,
    do_sample=True,
)
print(tokenizer.decode(tokens[0], skip_special_tokens=True))

In this code, you can think of FuseLLM-7B as a chef who has several cookbooks (the individual LLMs). When you give the chef (model) a new recipe (input text), they reference their extensive collection of cookbooks to create a delicious dish (output text) that combines the best ingredients (knowledge) from all sources.

Data Construction and Training

To ensure optimal performance, specific data construction and training scripts are necessary:

1. Split your dataset using a script provided in the repository.
2. Get representations for each LLM.
3. Align these representations to create a unified model.
4. Pack all features to speed up the training process.

As merging knowledge from different sources is like solving a jigsaw puzzle, careful alignment of pieces (the data) is crucial for a complete picture (effective model). If you encounter issues during this process, ensure you are using the correct dataset paths and that dependencies are properly installed.

Evaluation of FuseLLM

Post-training, it’s essential to evaluate your model’s performance across diverse benchmarks:

• AI2 Reasoning Challenge
• HellaSwag
• MMLU

These benchmarks assess how well FuseLLM can handle various text generation tasks, ensuring that the knowledge fusion process has been effective.

Troubleshooting Tips

If you encounter any issues, here are some troubleshooting ideas:

• Ensure your Python version is correct.
• Double-check that all dependencies are installed as per the requirements.txt.
• Verify that all paths provided in your scripts are correct.
• If the model fails to load, consider checking your CUDA setup and GPU availability.
