Build, modify, and control your own personalized LLMs
___
`xTuring` provides fast, efficient and simple fine-tuning of open-source LLMs, such as Mistral, LLaMA, GPT-J, and more.
By providing an easy-to-use interface for fine-tuning LLMs to your own data and application, xTuring makes it
simple to build, modify, and control LLMs. The entire process can be done inside your computer or in your
private cloud, ensuring data privacy and security.
With `xTuring` you can,
- Ingest data from different sources and preprocess them to a format LLMs can understand
- Scale from single to multiple GPUs for faster fine-tuning
- Leverage memory-efficient methods (i.e. INT4, LoRA fine-tuning) to reduce hardware costs by up to 90%
- Explore different fine-tuning methods and benchmark them to find the best performing model
- Evaluate fine-tuned models on well-defined metrics for in-depth analysis
## ⚙️ Installation
```bash
pip install xturing
```
## 🚀 Quickstart
```python
from xturing.datasets import InstructionDataset
from xturing.models import BaseModel
# Load the dataset
instruction_dataset = InstructionDataset("./examples/models/llama/alpaca_data")
# Initialize the model
model = BaseModel.create("llama_lora")
# Finetune the model
model.finetune(dataset=instruction_dataset)
# Perform inference
output = model.generate(texts=["Why LLM models are becoming so important?"])
print("Generated output by the model: {}".format(output))
```
You can find the data folder [here](examples/models/llama/alpaca_data).
## 🌟 What's new?
We are excited to announce the latest enhancements to our `xTuring` library:
1. __`LLaMA 2` integration__ - You can use and fine-tune the _`LLaMA 2`_ model in different configurations: _off-the-shelf_, _off-the-shelf with INT8 precision_, _LoRA fine-tuning_, _LoRA fine-tuning with INT8 precision_ and _LoRA fine-tuning with INT4 precision_ using the `GenericModel` wrapper and/or you can use the `Llama2` class from `xturing.models` to test and finetune the model.
```python
from xturing.models import Llama2
model = Llama2()
## or
from xturing.models import BaseModel
model = BaseModel.create('llama2')
```
2. __`Evaluation`__ - Now you can evaluate any `Causal Language Model` on any dataset. The metrics currently supported is [`perplexity`](https://en.wikipedia.org/wiki/Perplexity).
```python
# Make the necessary imports
from xturing.datasets import InstructionDataset
from xturing.models import BaseModel
# Load the desired dataset
dataset = InstructionDataset('../llama/alpaca_data')
# Load the desired model
model = BaseModel.create('gpt2')
# Run the Evaluation of the model on the dataset
result = model.evaluate(dataset)
# Print the result
print(f"Perplexity of the evalution: {result}")
```
3. __`INT4` Precision__ - You can now use and fine-tune any LLM with `INT4 Precision` using `GenericLoraKbitModel`.
```python
# Make the necessary imports
from xturing.datasets import InstructionDataset
from xturing.models import GenericLoraKbitModel
# Load the desired dataset
dataset = InstructionDataset('../llama/alpaca_data')
# Load the desired model for INT4 bit fine-tuning
model = GenericLoraKbitModel('tiiuae/falcon-7b')
# Run the fine-tuning
model.finetune(dataset)
```
4. __CPU inference__ - The CPU, including laptop CPUs, is now fully equipped to handle LLM inference. We integrated [Intel® Extension for Transformers](https://github.com/intel/intel-extension-for-transformers) to conserve memory by compressing the model with [weight-only quantization algorithms](https://github.com/intel/intel-extension-for-transformers/blob/main/docs/weightonlyquant.md) and accelerate the inference by leveraging its highly optimized kernel on Intel platforms.
```python
# Make the necessary imports
from xturing.models import BaseModel
# Initializes the model: quantize the model with weight-only algorithms
# and replace the linear with Itrex's qbits_linear kernel
model = BaseModel.create("llama2_int8")
# Once the model has been quantized, do inferences directly
output = model.generate(texts=["Why LLM models are becoming so important?"])
print(output)
```
5. __Batch integration__ - By tweaking the 'batch_size' in the .generate() and .evaluate() functions, you can expedite results. Using a 'batch_size' greater than 1 typically enhances processing efficiency.
```python
# Make the necessary imports
from xturing.datasets import InstructionDataset
from xturing.models import GenericLoraKbitModel
# Load the desired dataset
dataset = InstructionDataset('../llama/alpaca_data')
# Load the desired model for INT4 bit fine-tuning
model = GenericLoraKbitModel('tiiuae/falcon-7b')
# Generate outputs on desired prompts
outputs = model.generate(dataset = dataset, batch_size=10)
```
An exploration of the [Llama LoRA INT4 working example](examples/features/int4_finetuning/LLaMA_lora_int4.ipynb) is recommended for an understanding of its application.
For an extended insight, consider examining the [GenericModel working example](examples/features/generic/generic_model.py) available in the repository.
## CLI playground
```bash
$ xturing chat -m ""
```
## UI playground
```python
from xturing.datasets import InstructionDataset
from xturing.models import BaseModel
from xturing.ui import Playground
dataset = InstructionDataset("./alpaca_data")
model = BaseModel.create("")
model.finetune(dataset=dataset)
model.save("llama_lora_finetuned")
Playground().launch() ## launches localhost UI
```

## 📊 Performance
Here is a comparison for the performance of different fine-tuning techniques on the LLaMA 7B model. We use the [Alpaca dataset](examples/models/llama/alpaca_data/) for fine-tuning. The dataset contains 52K instructions.
Hardware:
4xA100 40GB GPU, 335GB CPU RAM
Fine-tuning parameters:
```javascript
{
'maximum sequence length': 512,
'batch size': 1,
}
```
| LLaMA-7B | DeepSpeed + CPU Offloading | LoRA + DeepSpeed | LoRA + DeepSpeed + CPU Offloading |
| :---------: | :----: | :----: | :----: |
| GPU | 33.5 GB | 23.7 GB | 21.9 GB |
| CPU | 190 GB | 10.2 GB | 14.9 GB |
| Time/epoch | 21 hours | 20 mins | 20 mins |
Contribute to this by submitting your performance results on other GPUs by creating an issue with your hardware specifications, memory consumption and time per epoch.
## 📎 Fine-tuned model checkpoints
We have already fine-tuned some models that you can use as your base or start playing with.
Here is how you would load them:
```python
from xturing.models import BaseModel
model = BaseModel.load("x/distilgpt2_lora_finetuned_alpaca")
```
| model | dataset | Path |
|---------------------|--------|---------------|
| DistilGPT-2 LoRA | alpaca | `x/distilgpt2_lora_finetuned_alpaca` |
| LLaMA LoRA | alpaca | `x/llama_lora_finetuned_alpaca` |
## Supported Models
Below is a list of all the supported models via `BaseModel` class of `xTuring` and their corresponding keys to load them.
| Model | Key |
| -- | -- |
|Bloom | bloom|
|Cerebras | cerebras|
|DistilGPT-2 | distilgpt2|
|Falcon-7B | falcon|
|Galactica | galactica|
|GPT-J | gptj|
|GPT-2 | gpt2|
|LlaMA | llama|
|LlaMA2 | llama2|
|OPT-1.3B | opt|
The above mentioned are the base variants of the LLMs. Below are the templates to get their `LoRA`, `INT8`, `INT8 + LoRA` and `INT4 + LoRA` versions.
| Version | Template |
| -- | -- |
| LoRA| _lora|
| INT8| _int8|
| INT8 + LoRA| _lora_int8|
** In order to load any model's __`INT4+LoRA`__ version, you will need to make use of `GenericLoraKbitModel` class from `xturing.models`. Below is how to use it:
```python
model = GenericLoraKbitModel('')
```
The `model_path` can be replaced with you local directory or any HuggingFace library model like `facebook/opt-1.3b`.
