<center><img src="MobileLLaMa.png" alt="mobillama logo" width="300"/></center>

## Model Summary

MobiLlama-05B is a Small Language Model with **0.5 billion** parameters. It was trained using the Amber data sources [Amber-Dataset](https://huggingface.co/datasets/LLM360/AmberDatasets). 


## Model Description

- **Model type:** Small Language Model (SLM) built using the architecture design of LLaMA-7B 
- **Language(s) (NLP):** English
- **License:** Apache 2.0
- **Resources for more information:**
  - [Training Code](https://github.com/LLM360/amber-train)
  - [Data Preparation](https://github.com/LLM360/amber-data-prep)
  - [Metrics](https://github.com/LLM360/Analysis360)
  - [Fully processed Amber pretraining data](https://huggingface.co/datasets/LLM360/AmberDatasets)

 
## How to Use

MobiLlama-05B has been integrated in the development version (4.37.0.dev) of `transformers`. Until the official version is released through `pip`, ensure that you are doing one of the following:

* When loading the model, ensure that `trust_remote_code=True` is passed as an argument of the `from_pretrained()` function.

* Update your local `transformers` to the development version: `pip uninstall -y transformers && pip install git+https://github.com/huggingface/transformers`. The previous command is an alternative to cloning and installing from the source.

The current `transformers` version can be verified with: `pip list | grep transformers`.

To load a specific checkpoint, simply pass a revision with a value between `"ckpt_000"` and `"ckpt_358"`. If no revision is provided, it will load `"ckpt_359"`, which is the final checkpoint.

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

torch.set_default_device("cuda")

model = AutoModelForCausalLM.from_pretrained("MBZUAI/MobiLlama-05B", torch_dtype="auto", trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained("MBZUAI/MobiLlama-05B", trust_remote_code=True)

text = "Write a C language program to find fibonnaci series?"
input_ids = tokenizer(text, return_tensors="pt").to('cuda').input_ids
outputs = model.generate(input_ids, max_length=1000, repetition_penalty=1.2, pad_token_id=tokenizer.eos_token_id)
print(tokenizer.batch_decode(outputs[:, input_ids.shape[1]:-1])[0].strip())

```
