Falcon H1 1.5B Deep Base

🚀 Falcon-H1 Model

The Falcon-H1 is a hybrid-head language model family that redefines efficiency and performance, supporting multiple languages.

🚀 Quick Start

To start using the Falcon-H1 model, you can choose from Hugging Face transformers, vLLM, or our custom fork of the llama.cpp library.

✨ Features

• Developed by: https://www.tii.ae
• Model type: Causal decoder-only
• Architecture: Hybrid Transformers + Mamba architecture
• Language(s) (NLP): English, Multilingual
• License: Falcon-LLM License

📦 Installation

Install transformers

pip install git+https://github.com/huggingface/transformers.git

Refer to the official vLLM documentation for more details on building vLLM from source.

💻 Usage Examples

Basic Usage

Using transformers

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "tiiuae/Falcon-H1-1B-Base"

model = AutoModelForCausalLM.from_pretrained(
  model_id,
  torch_dtype=torch.bfloat16,
  device_map="auto"
)

# Perform text generation

Using vLLM

# pip install vllm
vllm serve tiiuae/Falcon-H1-1B-Instruct --tensor-parallel-size 2 --data-parallel-size 1

Using llama.cpp

You can install our fork of the library and use it directly: https://github.com/tiiuae/llama.cpp-Falcon-H1. Use the same installing guidelines as llama.cpp.
