# What is Yi?

## Introduction 

- 🤖 The Yi series models are the next generation of open-source large language models trained from scratch by [01.AI](https://01.ai/).

- 🙌 Targeted as a bilingual language model and trained on 3T multilingual corpus, the Yi series models become one of the strongest LLM worldwide, showing promise in language understanding, commonsense reasoning, reading comprehension, and more. For example,
  
  - Yi-34B-Chat model **landed in second place (following GPT-4 Turbo)**, outperforming other LLMs (such as GPT-4, Mixtral, Claude) on the AlpacaEval Leaderboard (based on data available up to January 2024).

  - Yi-34B model **ranked first among all existing open-source models** (such as Falcon-180B, Llama-70B, Claude) in **both English and Chinese** on various benchmarks, including Hugging Face Open LLM Leaderboard (pre-trained) and C-Eval (based on data available up to November 2023).
  
  - 🙏 (Credits to Llama) Thanks to the Transformer and Llama open-source communities, as they reduce the efforts required to build from scratch and enable the utilization of the same tools within the AI ecosystem.  

  <details style="display: inline;"><summary> If you're interested in Yi's adoption of Llama architecture and license usage policy, see  <span style="color:  green;">Yi's relation with Llama.</span> ⬇️</summary> <ul> <br>
  
  
> 💡 TL;DR
> 
> The Yi series models adopt the same model architecture as Llama but are **NOT** derivatives of Llama.

- Both Yi and Llama are based on the Transformer structure, which has been the standard architecture for large language models since 2018.

- Grounded in the Transformer architecture, Llama has become a new cornerstone for the majority of state-of-the-art open-source models due to its excellent stability, reliable convergence, and robust compatibility. This positions Llama as the recognized foundational framework for models including Yi.

- Thanks to the Transformer and Llama architectures, other models can leverage their power, reducing the effort required to build from scratch and enabling the utilization of the same tools within their ecosystems.

- However, the Yi series models are NOT derivatives of Llama, as they do not use Llama's weights.

  - As Llama's structure is employed by the majority of open-source models, the key factors of determining model performance are training datasets, training pipelines, and training infrastructure.

  - Developing in a unique and proprietary way, Yi has independently created its own high-quality training datasets, efficient training pipelines, and robust training infrastructure entirely from the ground up. This effort has led to excellent performance with Yi series models ranking just behind GPT4 and surpassing Llama on the [Alpaca Leaderboard in Dec 2023](https://tatsu-lab.github.io/alpaca_eval/).

- For chat models
  
  <details style="display: inline;"><summary>For chat model limitations, see the explanations below. ⬇️</summary>
   <ul>
    <br>The released chat model has undergone exclusive training using Supervised Fine-Tuning (SFT). Compared to other standard chat models, our model produces more diverse responses, making it suitable for various downstream tasks, such as creative scenarios. Furthermore, this diversity is expected to enhance the likelihood of generating higher quality responses, which will be advantageous for subsequent Reinforcement Learning (RL) training.

    <br>However, this higher diversity might amplify certain existing issues, including:
      <li>Hallucination: This refers to the model generating factually incorrect or nonsensical information. With the model's responses being more varied, there's a higher chance of hallucination that are not based on accurate data or logical reasoning.</li>
      <li>Non-determinism in re-generation: When attempting to regenerate or sample responses, inconsistencies in the outcomes may occur. The increased diversity can lead to varying results even under similar input conditions.</li>
      <li>Cumulative Error: This occurs when errors in the model's responses compound over time. As the model generates more diverse responses, the likelihood of small inaccuracies building up into larger errors increases, especially in complex tasks like extended reasoning, mathematical problem-solving, etc.</li>
      <li>To achieve more coherent and consistent responses, it is advisable to adjust generation configuration parameters such as temperature, top_p, or top_k. These adjustments can help in the balance between creativity and coherence in the model's outputs.</li>

</p>

### Quick start - pip 

This tutorial guides you through every step of running **Yi-34B-Chat locally on an A800 (80G)** and then performing inference.

#### Step 0: Prerequisites

- Make sure Python 3.10 or a later version is installed.

- If you want to run other Yi models, see [software and hardware requirements](#deployment).

#### Step 1: Prepare your environment 

To set up the environment and install the required packages, execute the following command.

```bash
git clone https://github.com/01-ai/Yi.git
cd yi
pip install -r requirements.txt
```

#### Step 2: Download the Yi model

You can download the weights and tokenizer of Yi models from the following sources:

- [Hugging Face](https://huggingface.co/01-ai)
- [ModelScope](https://www.modelscope.cn/organization/01ai/)
- [WiseModel](https://wisemodel.cn/organization/01.AI)

#### Step 3: Perform inference

You can perform inference with Yi chat or base models as below.

##### Perform inference with Yi chat model

1. Create a file named  `quick_start.py` and copy the following content to it.

    ```python
    from transformers import AutoModelForCausalLM, AutoTokenizer

    model_path = '<your-model-path>'

    tokenizer = AutoTokenizer.from_pretrained(model_path, use_fast=False)

    # Since transformers 4.35.0, the GPT-Q/AWQ model can be loaded using AutoModelForCausalLM.
    model = AutoModelForCausalLM.from_pretrained(
        model_path,
        device_map="auto",
        torch_dtype='auto'
    ).eval()

    # Prompt content: "hi"
    messages = [
        {"role": "user", "content": "hi"}
    ]

    input_ids = tokenizer.apply_chat_template(conversation=messages, tokenize=True, add_generation_prompt=True, return_tensors='pt')
    output_ids = model.generate(input_ids.to('cuda'))
    response = tokenizer.decode(output_ids[0][input_ids.shape[1]:], skip_special_tokens=True)

    # Model response: "Hello! How can I assist you today?"
    print(response)
    ```

2. Run `quick_start.py`.

    ```bash
    python quick_start.py
    ```

    Then you can see an output similar to the one below. 🥳

    ```bash
    Hello! How can I assist you today?
    ```

##### Perform inference with Yi base model

- Yi-34B

  The steps are similar to [pip - Perform inference with Yi chat model](#perform-inference-with-yi-chat-model).

  You can use the existing file [`text_generation.py`](https://github.com/01-ai/Yi/tree/main/demo).

  ```bash
  python demo/text_generation.py  --model <your-model-path>
  ```

  Then you can see an output similar to the one below. 🥳

One day when I was playing at home alone, I found one of the tomcats lying on his back near our kitchen door, looking very much like he wanted something from us but couldn’t get up because there were too many people around him! He kept trying for several minutes before finally giving up...

```bash
git-lfs pull --include yi-chat-6b.Q2_K.gguf
```

#### Step 3: Perform inference

To perform inference with the Yi model, you can use one of the following methods.

- [Method 1: Perform inference in terminal](#method-1-perform-inference-in-terminal)
  
- [Method 2: Perform inference in web](#method-2-perform-inference-in-web)

##### Method 1: Perform inference in terminal

To compile `llama.cpp` using 4 threads and then conduct inference, navigate to the `llama.cpp` directory, and run the following command.

> ##### Tips
> 
> - Replace `/Users/yu/yi-chat-6B-GGUF/yi-chat-6b.Q2_K.gguf` with the actual path of your model.
>
> - By default, the model operates in completion mode.
> 
> - For additional output customization options (for example, system prompt, temperature, repetition penalty, etc.), run `./main -h` to check detailed descriptions and usage.

```bash
make -j4 && ./main -m /Users/yu/yi-chat-6B-GGUF/yi-chat-6b.Q2_K.gguf -p "How do you feed your pet fox? Please answer this question in 6 simple steps:\nStep 1:" -n 384 -e

...

How do you feed your pet fox? Please answer this question in 6 simple steps:

Step 1: Select the appropriate food for your pet fox. You should choose high-quality, balanced prey items that are suitable for their unique dietary needs. These could include live or frozen mice, rats, pigeons, or other small mammals, as well as fresh fruits and vegetables.

Step 2: Feed your pet fox once or twice a day, depending on the species and its individual preferences. Always ensure that they have access to fresh water throughout the day.

Step 3: Provide an appropriate environment for your pet fox. Ensure it has a comfortable place to rest, plenty of space to move around, and opportunities to play and exercise.

Step 4: Socialize your pet with other animals if possible. Interactions with other creatures can help them develop social skills and prevent boredom or stress.

Step 5: Regularly check for signs of illness or discomfort in your fox. Be prepared to provide veterinary care as needed, especially for common issues such as parasites, dental health problems, or infections.

Step 6: Educate yourself about the needs of your pet fox and be aware of any potential risks or concerns that could affect their well-being. Regularly consult with a veterinarian to ensure you are providing the best care.

### Fine-tuning

```bash
bash finetune/scripts/run_sft_Yi_6b.sh
```

Once finished, you can compare the finetuned model and the base model with the following command:

```bash
bash finetune/scripts/run_eval.sh
```
<details style="display: inline;"><summary>For advanced usage (like fine-tuning based on your custom data), see the explanations below. ⬇️ </summary> <ul>

### Finetune code for Yi 6B and 34B

#### Preparation

##### From Image

By default, we use a small dataset from [BAAI/COIG](https://huggingface.co/datasets/BAAI/COIG) to finetune the base model.
You can also prepare your customized dataset in the following `jsonl` format:

```json
{ "prompt": "Human: Who are you? Assistant:", "chosen": "I'm Yi." }
```

And then mount them in the container to replace the default ones:

```bash
docker run -it \
    -v /path/to/save/finetuned/model/:/finetuned-model \
    -v /path/to/train.jsonl:/yi/finetune/data/train.json \
    -v /path/to/eval.jsonl:/yi/finetune/data/eval.json \
    ghcr.io/01-ai/yi:latest \
    bash finetune/scripts/run_sft_Yi_6b.sh
```

##### From Local Server

Make sure you have conda. If not, use

```bash
mkdir -p ~/miniconda3
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda3/miniconda.sh
bash ~/miniconda3/miniconda.sh -b -u -p ~/miniconda3
rm -rf ~/miniconda3/miniconda.sh
~/miniconda3/bin/conda init bash
source ~/.bashrc
```

Then, create a conda env:

```bash
conda create -n dev_env python=3.10 -y
conda activate dev_env
pip install torch==2.0.1 deepspeed==0.10 tensorboard transformers datasets sentencepiece accelerate ray==2.7
```

#### Hardware Setup

For the Yi-6B model, a node with 4 GPUs, each with GPU memory larger than 60GB, is recommended.

For the Yi-34B model, because the usage of the zero-offload technique consumes a lot of CPU memory, please be careful to limit the number of GPUs in the 34B finetune training. Please use CUDA_VISIBLE_DEVICES to limit the number of GPUs (as shown in scripts/run_sft_Yi_34b.sh).

A typical hardware setup for finetuning the 34B model is a node with 8 GPUs (limited to 4 in running by CUDA_VISIBLE_DEVICES=0,1,2,3), each with GPU memory larger than 80GB, and total CPU memory larger than 900GB.

#### Quick Start

Download a LLM-base model to MODEL_PATH (6B and 34B). A typical folder of models is like:

```bash
|-- $MODEL_PATH
|   |-- config.json
|   |-- pytorch_model-00001-of-00002.bin
|   |-- pytorch_model-00002-of-00002.bin
|   |-- pytorch_model.bin.index.json
|   |-- tokenizer_config.json
|   |-- tokenizer.model
|   |-- ...
```

Download a dataset from huggingface to local storage DATA_PATH, e.g. Dahoas/rm-static.

```bash
|-- $DATA_PATH
|   |-- data
|   |   |-- train-00000-of-00001-2a1df75c6bce91ab.parquet
|   |   |-- test-00000-of-00001-8c7c51afc6d45980.parquet
|   |-- dataset_infos.json
|   |-- README.md
```

`finetune/yi_example_dataset` has example datasets, which are modified from [BAAI/COIG](https://huggingface.co/datasets/BAAI/COIG)

```bash
|-- $DATA_PATH
    |--data
        |-- train.jsonl
        |-- eval.jsonl
```

`cd` into the scripts folder, copy and paste the script, and run. For example:

```bash
cd finetune/scripts

bash run_sft_Yi_6b.sh
```

For the Yi-6B base model, setting training_debug_steps=20 and num_train_epochs=4 can output a chat model, which takes about 20 minutes.

For the Yi-34B base model, it takes a relatively long time for initialization. Please be patient.

#### Evaluation

```bash
cd finetune/scripts

bash run_eval.sh
```

Then you'll see the answer from both the base model and the finetuned model.

  --trust_remote_code
```

<details style="display: inline;"><summary>For details, see the explanations below. ⬇️</summary> <ul>

#### GPT-Q quantization

[GPT-Q](https://github.com/IST-DASLab/gptq) is a PTQ (Post-Training Quantization)
method. It saves memory and provides potential speedups while retaining the accuracy
of the model. 

Yi models can be GPT-Q quantized without a lot of efforts. 
We provide a step-by-step tutorial below.

To run GPT-Q, we will use [AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) and
[exllama](https://github.com/turboderp/exllama).
And the huggingface transformers has integrated optimum and auto-gptq to perform
GPTQ quantization on language models.

##### Do Quantization

The `quant_autogptq.py` script is provided for you to perform GPT-Q quantization:

```bash
python quant_autogptq.py --model /base_model \
    --output_dir /quantized_model --bits 4 --group_size 128 --trust_remote_code
```

##### Run Quantized Model

You can run a quantized model using the `eval_quantized_model.py`:

```bash
python eval_quantized_model.py --model /quantized_model --trust_remote_code
```
</ul>

#### AWQ

```bash
python quantization/awq/quant_autoawq.py \
  --model /base_model                      \
  --output_dir /quantized_model            \
  --trust_remote_code
```

Once finished, you can then evaluate the resulting model as follows:

```bash
python quantization/awq/eval_quantized_model.py \
  --model /quantized_model                       \
  --trust_remote_code
```
<details style="display: inline;"><summary>For details, see the explanations below. ⬇️</summary> <ul>

#### AWQ quantization

[AWQ](https://github.com/mit-han-lab/llm-awq) is a PTQ (Post-Training Quantization)
method. It's an efficient and accurate low-bit weight quantization (INT3/4) for LLMs.

Yi models can be AWQ quantized without a lot of efforts. 
We provide a step-by-step tutorial below.

To run AWQ, we will use [AutoAWQ](https://github.com/casper-hansen/AutoAWQ).

##### Do Quantization

The `quant_autoawq.py` script is provided for you to perform AWQ quantization:

```bash
python quant_autoawq.py --model /base_model \
    --output_dir /quantized_model --bits 4 --group_size 128 --trust_remote_code
```

##### Run Quantized Model

  <br>The choice of pre-trained language model for fine-tuning hinges on the computational resources you have at your disposal and the particular demands of your task.
    - If you are working with a substantial volume of fine-tuning data (say, over 10,000 samples), the Base model could be your go-to choice.
    - On the other hand, if your fine-tuning data is not quite as extensive, opting for the Chat model might be a more fitting choice.
    - It is generally advisable to fine-tune both the Base and Chat models, compare their performance, and then pick the model that best aligns with your specific requirements.
- <strong>Yi-34B versus Yi-34B-Chat for full-scale fine-tuning - what is the difference?</strong>
  <br>
  The key distinction between full-scale fine-tuning on `Yi-34B`and `Yi-34B-Chat` comes down to the fine-tuning approach and outcomes.
    - Yi-34B-Chat employs a Special Fine-Tuning (SFT) method, resulting in responses that mirror human conversation style more closely.
    - The Base model's fine-tuning is more versatile, with a relatively high performance potential.
    - If you are confident in the quality of your data, fine-tuning with `Yi-34B` could be your go-to.
    - If you are aiming for model-generated responses that better mimic human conversational style, or if you have doubts about your data quality, `Yi-34B-Chat` might be your best bet.

#### 💡Quantization
- <strong>Quantized model versus original model - what is the performance gap?</strong>
    - The performance variance is largely contingent on the quantization method employed and the specific use cases of these models. For instance, when it comes to models provided by the AWQ official, from a Benchmark standpoint, quantization might result in a minor performance drop of a few percentage points.
    - Subjectively speaking, in situations like logical reasoning, even a 1% performance shift could impact the accuracy of the output results.
    
#### 💡General
- <strong>Where can I source fine-tuning question answering datasets?</strong>
    - You can find fine-tuning question answering datasets on platforms like Hugging Face, with datasets like [m-a-p/COIG-CQIA](https://huggingface.co/datasets/m-a-p/COIG-CQIA) readily available. 
    - Additionally, Github offers fine-tuning frameworks, such as [hiyouga/LLaMA-Factory](https://github.com/hiyouga/LLaMA-Factory), which integrates pre-made datasets.

- <strong>What is the GPU memory requirement for fine-tuning Yi-34B FP16?</strong>
  <br>
  The GPU memory needed for fine-tuning 34B FP16 hinges on the specific fine-tuning method employed. For full parameter fine-tuning, you'll need 8 GPUs each with 80 GB; however, more economical solutions like Lora require less. For more details, check out [hiyouga/LLaMA-Factory](https://github.com/hiyouga/LLaMA-Factory). Also, consider using BF16 instead of FP16 for fine-tuning to optimize performance.

- <strong>Are there any third-party platforms that support chat functionality for the Yi-34b-200k model?</strong>
  <br>
  If you're looking for third-party Chats, options include [fireworks.ai](https://fireworks.ai/login?callbackURL=https://fireworks.ai/models/fireworks/yi-34b-chat).

### Upstream

The Yi series models follow the same model architecture as Llama. By choosing Yi, you can leverage existing tools, libraries, and resources within the Llama ecosystem, eliminating the need to create new tools and enhancing development efficiency.

For example, the Yi series models are saved in the format of the Llama model. You can directly use `LlamaForCausalLM` and `LlamaTokenizer` to load the model. For more information, see [Use the chat model](#31-use-the-chat-model).

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("01-ai/Yi-34b", use_fast=False)

model = AutoModelForCausalLM.from_pretrained("01-ai/Yi-34b", device_map="auto")
```

</p>

### Downstream

> 💡 Tip
> 
> - Feel free to create a PR and share the fantastic work you've built using the Yi series models.
>
> - To help others quickly understand your work, it is recommended to use the format of `<model-name>: <model-intro> + <model-highlights>`.

## Benchmarks 

- [Chat model performance](#chat-model-performance)
- [Base model performance](#base-model-performance)

### Chat model performance

Yi-34B-Chat model demonstrates exceptional performance, ranking first among all existing open-source models in the benchmarks including MMLU, CMMLU, BBH, GSM8k, and more.

![Chat model performance](https://github.com/01-ai/Yi/blob/main/assets/img/benchmark_chat.png?raw=true) 

<details>
<summary> Evaluation methods and challenges. ⬇️ </summary>

- **Evaluation methods**: we evaluated various benchmarks using both zero-shot and few-shot methods, except for TruthfulQA.
- **Zero-shot vs. few-shot**: in chat models, the zero-shot approach is more commonly employed.
- **Evaluation strategy**: our evaluation strategy involves generating responses while following instructions explicitly or implicitly (such as using few-shot examples). We then isolate relevant answers from the generated text.
- **Challenges faced**: some models are not well-suited to produce output in the specific format required by instructions in few datasets, which leads to suboptimal results.

<strong>*</strong>: C-Eval results are evaluated on the validation datasets

### Base model performance

#### Yi-34B and Yi-34B-200K 

The Yi-34B and Yi-34B-200K models stand out as the top performers among open-source models, especially excelling in MMLU, CMMLU, common-sense reasoning, reading comprehension, and more.

<details>
<summary> Evaluation methods. ⬇️</summary>

- **Disparity in results**: while benchmarking open-source models, a disparity has been noted between results from our pipeline and those reported by public sources like OpenCompass.
- **Investigation findings**: a deeper investigation reveals that variations in prompts, post-processing strategies, and sampling techniques across models may lead to significant outcome differences.
- **Uniform benchmarking process**: our methodology aligns with the original benchmarks—consistent prompts and post-processing strategies are used, and greedy decoding is applied during evaluations without any post-processing for the generated content.
- **Efforts to retrieve unreported scores**: for scores that were not reported by the original authors (including scores reported with different settings), we try to get results with our pipeline.
- **Extensive model evaluation**: to evaluate the model’s capability extensively, we adopted the methodology outlined in Llama2. Specifically, we included PIQA, SIQA, HellaSwag, WinoGrande, ARC, OBQA, and CSQA to assess common sense reasoning. SquAD, QuAC, and BoolQ were incorporated to evaluate reading comprehension.
- **Special configurations**: CSQA was exclusively tested using a 7-shot setup, while all other tests were conducted with a 0-shot configuration. Additionally, we introduced GSM8K (8-shot@1), MATH (4-shot@1), HumanEval (0-shot@1), and MBPP (3-shot@1) under the category "Math & Code".
- **Falcon-180B caveat**: Falcon-180B was not tested on QuAC and OBQA due to technical constraints. Its performance score is an average from other tasks, and considering the generally lower scores of these two tasks, Falcon-180B's capabilities are likely not underestimated.
