# FalconH1

## Overview

The [FalconH1](https://huggingface.co/blog/tiiuae/falcon-h1) model was developed by the TII Pretraining team. A comprehensive research paper covering the architecture, pretraining dynamics, experimental results, and conclusions is forthcoming. You can read more about this series in [this website](https://github.com/tiiuae/Falcon-H1).

## FalconH1ForCausalLM

```python
from transformers import AutoModelForCausalLM, AutoTokenizer


model = AutoModelForCausalLM.from_pretrained("tiiuae/Falcon-H1-7B-Instruct", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("tiiuae/Falcon-H1-7B-Instruct")

message = ["Mamba is a snake with following properties  "]
inputs = tokenizer(message, return_tensors='pt', return_token_type_ids=False).to(model.device)
response = model.generate(**inputs, max_new_tokens=64)
print(tokenizer.batch_decode(response, skip_special_tokens=True)[0])
