# TL;DR

# Model Details

## Model Description

- **Developed by:** [https://www.tii.ae](https://www.tii.ae)
- **Model type:** Causal decoder-only / Base version
- **Architecture:** Pure-transformer - 1.58bit version
- **Language(s) (NLP):** English
- **License:** Falcon-LLM License

# Training details

For more details about the training protocol of this model, please refer to the [Falcon-E technical blogpost](https://falcon-lm.github.io/blog/falcon-edge/).

# Usage

Currently to use this model you can either rely on Hugging Face transformers library or [BitNet](https://github.com/microsoft/BitNet) library. There are multiple ways to interact with the model depending on your target usage. For each of the Falcon-E series model, you have three variants: the BitNet model, the prequantized checkpoint for fine-tuning and the `bfloat16` version of the BitNet model.

### Inference

#### BitNet

```
git clone https://github.com/microsoft/BitNet && cd BitNet
pip install -r requirements.txt
huggingface-cli download tiiuae/Falcon-E-3B-Instruct-GGUF ggml-model-i2_s.gguf --local-dir models/Falcon-E-3B-Instruct/
python run_inference.py -m models/Falcon-E-3B-Instruct/ggml-model-i2_s.gguf -p "You are a helpful assistant" -cnv
```

### Fine-tuning

For fine-tuning the model, you should load the `prequantized` revision of the model and use the `onebitllms` Python package:

```diff
import torch

from transformers import AutoModelForCausalLM, AutoTokenizer
from trl import SFTTrainer
+ from onebitllms import replace_linear_with_bitnet_linear, quantize_to_1bit

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

tokenizer = AutoTokenizer.from_pretrained(model_id, revision="prequantized")
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
+    revision="prequantized"
)
+ model = replace_linear_with_bitnet_linear(model)

trainer = SFTTrainer(
    model,
    ...
)

trainer.train()

+ quantize_to_1bit(output_directory)
```
