Introducing Falcon-40B and Falcon-7B: Open-Source Language Models for Enhanced Natural Language Processing

Introduction:

In the world of natural language processing, having access to powerful and versatile language models is crucial. The Technology Innovation Institute (TII), a renowned research center based in the UAE, has developed two cutting-edge open-source models, Falcon-40B and Falcon-7B. These models, equipped with state-of-the-art architecture and training techniques, offer advanced capabilities for a wide range of NLP tasks. In this blog post, we will delve into the technical details of Falcon-40B and Falcon-7B, highlighting their features, potential applications, and how you can get started with them.

Falcon-40B:

Unleashing the Power of Open-Source Language Models Falcon-40B is a decoder-only model with an impressive parameter count of 40 billion. Developed by TII and trained on an extensive dataset comprising 1,000 billion tokens from RefinedWeb, Falcon-40B sets a new benchmark in open-source language models. It outperforms several other models, including LLaMA, StableLM, RedPajama, and MPT, as validated by the OpenLLM Leaderboard. Its architecture is optimized for inference, leveraging advanced techniques such as FlashAttention and multiquery. The model is released under the permissive Apache 2.0 license, allowing unrestricted commercial use without any royalties or restrictions. While Falcon-40B is a pretrained model, fine-tuning it for specific use cases is recommended.

Falcon-7B:

A Compact Sibling Model For users seeking a smaller and more cost-effective option, Falcon-7B is an excellent choice. As Falcon-40B's little brother, Falcon-7B offers similar performance and features but with a reduced parameter count. This compact model maintains high-quality results while being more resource-efficient, making it suitable for a broader range of applications.

Applications of Falcon Models The Falcon models, with their powerful language processing capabilities, can be utilized in various ways:

1. Research on Large Language Models: Falcon-40B and Falcon-7B provide researchers with a solid foundation for investigating and advancing the field of language modeling. Their extensive parameter count and architecture make them ideal for exploring new techniques and applications.

2. Specialization and Fine-tuning: These models serve as starting points for further specialization and fine-tuning to address specific NLP tasks such as summarization, text generation, and chatbot development. Their versatility allows customization to suit a wide range of use cases.

Important Considerations and Recommendations While Falcon-40B and Falcon-7B offer powerful capabilities, it is important to consider the following:

1. Language Support and Bias: Falcon-40B is primarily trained on English, German, Spanish, and French, with limited capabilities in other languages. Generalizing to languages outside this scope may not yield accurate results. Additionally, since the models are trained on web data, they may carry stereotypes and biases commonly found online.

2. Fine-tuning for Specific Use Cases: To optimize the models for specific tasks, fine-tuning is recommended. By adapting the models to specific domains or requirements, users can enhance their performance and mitigate biases.

Getting Started with Falcon Models To get started with Falcon-40B and Falcon-7B, follow these steps:

1. Install the Required Dependencies: Ensure that you have PyTorch 2.0 and the Transformers library installed, as Falcon LLMs require PyTorch 2.0 for compatibility.

2. Choose the Model: Select the desired model, either Falcon-40B or Falcon-7B, based on your requirements.

3. Tokenization and Model Configuration: Use the AutoTokenizer class from Transformers to tokenize your input and configure the model and tokenizer accordingly.

4. Text Generation: Utilize the pipeline functionality provided by Transformers to generate text based on your desired prompt. Adjust parameters such as maximum length, sampling options, and number of return sequences as needed.

To run Falcon-40B on a single A100 GPU using Google Colab Pro, use the provided code snippet:

note:- This will only work with google collab pro only. Standard Plan won't work

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model = "tiiuae/falcon-40b" // for 7B Change this to "tiiuae/falcon-7b"

tokenizer = AutoTokenizer.from_pretrained(model)
pipeline = transformers.pipeline(
"text-generation",
model=model,
tokenizer=tokenizer,
torch_dtype=torch.bfloat16,
trust_remote_code=True,
device_map="auto",
)
sequences = pipeline(
"Girafatron is obsessed with giraffes, the most glorious animal on the face of this Earth. Giraftron believes all other animals are irrelevant when compared to the glorious majesty of the giraffe.\nDaniel: Hello, Girafatron!\nGirafatron:",
max_length=200,
do_sample=True,
top_k=10,
num_return_sequences=1,
eos_token_id=tokenizer.eos_token_id,
)
for seq in sequences:
print(f"Result: {seq['generated_text']}")

By executing this code in a Google Colab notebook, you can leverage the power of Falcon-40B for text generation tasks, taking advantage of the A100 GPU acceleration.

Can Falcon-40B quantize in 4bit?

Yes,

Conclusion: Falcon-40B and Falcon-7B, developed by the Technology Innovation Institute (TII), are remarkable additions to the world of open-source language models. Their extensive training, optimized architecture, and fine-tuning capabilities offer tremendous potential for advancing various natural language processing tasks. Whether you are a researcher exploring large language models or a developer specializing in NLP applications, Falcon models provide a solid foundation for innovation and customization. Remember to consider language support, potential biases, and the importance of fine-tuning for specific use cases. With Falcon models, you can unlock new horizons in natural language processing and pave the way for groundbreaking applications.
