Falcon H1 0.5B Instruct

🚀 Falcon-H1 Model

The Falcon-H1 is a powerful hybrid-head language model developed by TII, offering high efficiency and performance in various NLP tasks.

🚀 Quick Start

Currently, you can use this model with Hugging Face transformers, vLLM, or our custom fork of the llama.cpp library.

Installation

Make sure to install the latest version of transformers or vLLM. You can install these packages from source:

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

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

Inference

🤗 transformers

Refer to the snippet below to run H1 models 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

vLLM

For vLLM, simply start a server by executing the command below:

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

llama.cpp

While we are working on integrating our architecture directly into the llama.cpp library, 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.
