## What is ColossalChat and Coati ?
[ColossalChat](https://github.com/hpcaitech/ColossalAI/tree/main/applications/Chat) is the project to implement LLM with RLHF, powered by the [Colossal-AI](https://github.com/hpcaitech/ColossalAI) project.
Coati stands for `ColossalAI Talking Intelligence`. It is the name for the module implemented in this project and is also the name of the large language model developed by the ColossalChat project.
The Coati package provides a unified large language model framework that has implemented the following functions
- Supports comprehensive large-model training acceleration capabilities for ColossalAI, without requiring knowledge of complex distributed training algorithms
- Supervised datasets collection
- Supervised instructions fine-tuning
- Training reward model
- Reinforcement learning with human feedback
- Quantization inference
- Fast model deploying
- Perfectly integrated with the Hugging Face ecosystem, a high degree of model customization

## Install
### Install the environment
```bash
conda create -n coati
conda activate coati
git clone https://github.com/hpcaitech/ColossalAI.git
cd ColossalAI/applications/Chat
pip install .
```
### Install the Transformers
```bash
pip install transformers==4.30.2
```
## How to use?
### Supervised datasets collection
We collected 104K bilingual datasets of Chinese and English, and you can find the datasets in this repo
[InstructionWild](https://github.com/XueFuzhao/InstructionWild) and in this [file](https://github.com/XueFuzhao/InstructionWild/blob/main/data/README.md).
Here is how we collected the data
<p align="center">
<img src="https://raw.githubusercontent.com/hpcaitech/public_assets/main/applications/chat/data-collect.png" width=500/>
</p>
### RLHF Training Stage1 - Supervised instructs tuning
Stage1 is supervised instructs fine-tuning, which uses the datasets mentioned earlier to fine-tune the model.
You can run the `examples/train_sft.sh` to start a supervised instructs fine-tuning.
[[Stage1 tutorial video]](https://www.youtube.com/watch?v=-qFBZFmOJfg)
**Note**: the supervised dataset follows the following format,
```json
[
{
"instruction": "Provide a list of the top 10 most popular mobile games in Asia",
"input": "",
"output": "The top 10 most popular mobile games in Asia are:\n1) PUBG Mobile\n2) Pokemon Go\n3) Candy Crush Saga\n4) Free Fire\n5) Clash of Clans\n6) Mario Kart Tour\n7) Arena of Valor\n8) Fantasy Westward Journey\n9) Subway Surfers\n10) ARK Survival Evolved",
"id": 0
},
...
]
```
### RLHF Training Stage2 - Training reward model
Stage2 trains a reward model, which obtains corresponding scores by manually ranking different outputs for the same prompt and supervises the training of the reward model
You can run the `examples/train_rm.sh` to start a reward model training.
[[Stage2 tutorial video]](https://www.youtube.com/watch?v=gMx2CApKhuo)
### RLHF Training Stage3 - Training model with reinforcement learning by human feedback
Stage3 uses reinforcement learning algorithm, which is the most complex part of the training process:
<p align="center">
<img src="https://raw.githubusercontent.com/hpcaitech/public_assets/main/applications/chat/stage-3.jpeg" width=800/>
</p>
You can run the `examples/train_prompts.sh` to start training PPO with human feedback.
[[Stage3 tutorial video]](https://www.youtube.com/watch?v=Z8wwSHxPL9g)
**Note**: the required datasets follow the following format,
- `pretrain dataset`
```json
[
{
"instruction": "Provide a list of the top 10 most popular mobile games in Asia",
"input": "",
"output": "The top 10 most popular mobile games in Asia are:\n1) PUBG Mobile\n2) Pokemon Go\n3) Candy Crush Saga\n4) Free Fire\n5) Clash of Clans\n6) Mario Kart Tour\n7) Arena of Valor\n8) Fantasy Westward Journey\n9) Subway Surfers\n10) ARK Survival Evolved",
"id": 0
},
...
]
```
- `prompt dataset`
```json
[
{
"instruction": "Edit this paragraph to make it more concise: \"Yesterday, I went to the store and bought some things. Then, I came home and put them away. After that, I went for a walk and met some friends.\"",
"id": 0
},
{
"instruction": "Write a descriptive paragraph about a memorable vacation you went on",
"id": 1
},
...
]
```
For more details, see [`examples/`](https://github.com/hpcaitech/ColossalAI/tree/main/applications/Chat/examples).
### Inference Quantization and Serving - After Training
We provide an online inference server and a benchmark. We aim to run inference on single GPU, so quantization is essential when using large models.
We support 8-bit quantization (RTN), 4-bit quantization (GPTQ), and FP16 inference.
Online inference server scripts can help you deploy your own services.
For more details, see [`inference/`](https://github.com/hpcaitech/ColossalAI/tree/main/applications/Chat/inference).

### Limitation
<details><summary><b>Limitation for LLaMA-finetuned models</b></summary>
- Both Alpaca and ColossalChat are based on LLaMA. It is hard to compensate for the missing knowledge in the pre-training stage.
- Lack of counting ability: Cannot count the number of items in a list.
- Lack of Logics (reasoning and calculation)
- Tend to repeat the last sentence (fail to produce the end token).
- Poor multilingual results: LLaMA is mainly trained on English datasets (Generation performs better than QA).
</details>
<details><summary><b>Limitation of dataset</b></summary>
- Lack of summarization ability: No such instructions in finetune datasets.
- Lack of multi-turn chat: No such instructions in finetune datasets
- Lack of self-recognition: No such instructions in finetune datasets
- Lack of Safety:
- When the input contains fake facts, the model makes up false facts and explanations.
- Cannot abide by OpenAI's policy: When generating prompts from OpenAI API, it always abides by its policy. So no violation case is in the datasets.
</details>
## FAQ
<details><summary><b>How to save/load checkpoint</b></summary>
We have integrated the Transformers save and load pipeline, allowing users to freely call Hugging Face's language models and save them in the HF format.
```python
from coati.models.llama import LlamaLM
from coati.trainer import SFTTrainer
model = LlamaLM(pretrained=args.pretrain)
tokenizer = AutoTokenizer.from_pretrained(args.pretrain)
(model, optim) = strategy.prepare((model, optim))
trainer = SFTTrainer(model=model,
strategy=strategy,
optim=optim,
train_dataloader=train_dataloader,
eval_dataloader=eval_dataloader,
batch_size=args.batch_size,
max_epochs=args.max_epochs,
accumulation_steps=args.accumulation_steps
)
trainer.fit()
# this saves in pytorch format
strategy.save_model(model, args.save_path, only_rank0=True)
# this saves in HF format
strategy.save_pretrained(model, args.save_path, only_rank0=True, tokenizer=tokenizer)
```
</details>
<details><summary><b>How to train with limited resources</b></summary>
Here are some examples that can allow you to train a 7B model on a single or multiple consumer-grade GPUs.
If you only have a single 24G GPU, you can use the following script. `batch_size`, `lora_rank` and `grad_checkpoint` are the most important parameters to successfully train the model.
```bash
// [INFO]: MAX GPU MEMORY ALLOCATED: 19148.9345703125 MB
torchrun --standalone --nproc_per_node=1 train_sft.py \
--pretrain "/path/to/LLaMa-7B/" \
--model 'llama' \
--strategy ddp \
--save_path /path/to/Coati-7B \
--dataset /path/to/data.json \
--batch_size 1 \
--accumulation_steps 8 \
--lr 2e-5 \
--max_datasets_size 512 \
--max_epochs 1 \
--lora_rank 16 \
--grad_checkpoint
```
`colossalai_gemini` strategy can enable a single 24G GPU to train the whole model without using LoRA if you have sufficient CPU memory. You can use the following script.
```bash
torchrun --standalone --nproc_per_node=1 train_sft.py \
--pretrain "/path/to/LLaMa-7B/" \
--model 'llama' \
--strategy colossalai_gemini \
--save_path /path/to/Coati-7B \
--dataset /path/to/data.json \
--batch_size 1 \
--accumulation_steps 8 \
--lr 2e-5 \
--max_datasets_size 512 \
--max_epochs 1 \
--grad_checkpoint
```
If you have 4x32 GB GPUs, you can even train the whole 7B model using our `colossalai_zero2_cpu` strategy! The script is given as follows.
```bash
torchrun --standalone --nproc_per_node=4 train_sft.py \
--pretrain "/path/to/LLaMa-7B/" \
--model 'llama' \
--strategy colossalai_zero2_cpu \
--save_path /path/to/Coati-7B \
--dataset /path/to/data.json \
--batch_size 1 \
--accumulation_steps 8 \
--lr 2e-5 \
--max_datasets_size 512 \
--max_epochs 1 \
--grad_checkpoint
```

| Model Pair | Alpaca-7B ⚔ Coati-7B | Coati-7B ⚔ Alpaca-7B |
| :-----------: | :------------------: | :------------------: |
| Better Cases | 38 ⚔ **41** | **45** ⚔ 33 |
| Win Rate | 48% ⚔ **52%** | **58%** ⚔ 42% |
| Average Score | 7.06 ⚔ **7.13** | **7.31** ⚔ 6.82 |
- Our Coati-7B model performs better than Alpaca-7B when using GPT-4 to evaluate model performance. The Coati-7B model we evaluate is an old version we trained a few weeks ago and the new version is around the corner.
