# 📌 Introduction

In the field of large language models (LLMs) such as GPT, LLaMA, GLM, etc., while their performance is impressive, the
massive model parameters—often in the range of 10 billion—make them difficult to train or even infer on personal devices
with limited memory. Most users do not settle for merely fine-tuning large models using methods like LoRA to learn a few
new instructions. It's akin to teaching Newton to use a 21st-century smartphone, which is far removed from the essence
of learning physics itself.

Additionally, the abundance of flawed, superficial AI tutorials offered by subscription-based marketing accounts
exacerbates the problem of finding quality content to understand LLMs, severely hindering learners.

Therefore, the goal of this project is to lower the barrier to entry for working with LLMs as much as possible, by
training an extremely lightweight language model from scratch.

(As of August 28, 2024) The initial release of MiniMind includes four model variants, with the smallest being just
26MB (0.02B) and still exhibiting amazing conversational capabilities!

| Model (Size)           | Speed (Tokens/s) | Inference Memory | Training Memory (`batch_size=8`) | 
|------------------------|------------------|------------------|----------------------------------|
| MiniMind-small-T (26M) | 91.9             | 0.5 GB           | 3.6 GB                           |
| MiniMind-small (56M)   | 85.2             | 0.7 GB           | 4.5 GB                           |
| MiniMind (218M)        | 57.6             | 2.1 GB           | 10.4 GB                          |
| MiniMind-MoE (166M)    | 64.9             | 1.6 GB           | 7.4 GB                           |

> This analysis was conducted on an RTX 3090 GPU with Torch 2.1.2, CUDA 12.2, and Flash Attention 2.

The project includes:

- Public MiniMind model code (including Dense and MoE models), code for Pretrain, SFT instruction fine-tuning, LoRA
  fine-tuning, and DPO preference optimization, along with datasets and sources.
- Compatibility with popular frameworks such as `transformers`, `accelerate`, `trl`, and `peft`.
- Training support for single-GPU and multi-GPU setups(DDP、DeepSpeed). The training process allows for stopping and
  resuming at any
  point.
- Code for testing the model on the Ceval dataset.
- Implementation of a basic chat interface compatible with OpenAI's API, facilitating integration into third-party Chat
  UIs (such as FastGPT, Open-WebUI, etc.).

We hope this open-source project helps LLM beginners get started quickly!

# 📌 Data sources

- 🤖 Tokenizer: In NLP, a Tokenizer is similar to a dictionary, mapping words from natural language to numbers like 0, 1,
  36, etc., which can be understood as page numbers in the "dictionary" representing words. There are two ways to build
  an LLM tokenizer: one is to create a vocabulary and train a tokenizer yourself, as seen in `train_tokenizer.py`; the
  other is to use a pre-trained tokenizer from an open-source model.

  You can use a standard dictionary like Xinhua or Oxford. The advantage is that token conversion has a good compression
  rate, but the downside is that the vocabulary can be very large, with tens of thousands of words and phrases.
  Alternatively, you can use a custom-trained tokenizer. The advantage is that you can control the vocabulary size, but
  the compression rate may not be ideal, and rare words might be missed.

  The choice of "dictionary" is crucial. The output of an LLM is essentially a multi-class classification problem over N
  words in the dictionary, which is then decoded back into natural language. Because LLMs are very small, to avoid the
  model being top-heavy (with the embedding layer's parameters taking up too much of the model), the vocabulary length
  should be kept relatively small.

  Powerful open-source models like 01万物, 千问, chatglm, mistral, and Llama3 have the following tokenizer vocabulary
  sizes:
    <table>
      <tr><th>Tokenizer Model</th><th>Vocabulary Size</th><th>Come from</th></tr>
      <tr><td>yi tokenizer</td><td>64,000</td><td>01-AI（China）</td></tr>
      <tr><td>qwen2 tokenizer</td><td>151,643</td><td>Alibaba Cloud（China）</td></tr>
      <tr><td>glm tokenizer</td><td>151,329</td><td>Zhipu AI（China）</td></tr>
      <tr><td>mistral tokenizer</td><td>32,000</td><td>Mistral AI（China）</td></tr>
      <tr><td>llama3 tokenizer</td><td>128,000</td><td>Meta（China）</td></tr>
      <tr><td>minimind tokenizer</td><td>6,400</td><td>Custom</td></tr>
    </table>
  > Although Mistral’s Chinese vocabulary proportion is small and its encoding/decoding efficiency is weaker than
  Chinese-friendly tokenizers like qwen2 and glm, MiniMind chose the Mistral tokenizer to keep the overall model
  lightweight and avoid being top-heavy, as Mistral’s vocabulary size is only 32,000. MiniMind has shown excellent
  performance in practical tests, with almost no failures in decoding rare words.

  > For comparison purposes, an additional custom Tokenizer version **MiniMind(-T)** was trained, reducing the
  vocabulary size to 6,400, which further decreases the total model parameters to around 26M.

# 📌 Model

MiniMind-Dense (like [Llama3.1](https://ai.meta.com/blog/meta-llama-3-1/)) uses a Transformer Decoder-Only architecture.
The differences from GPT-3 are:

* It employs GPT-3's pre-normalization method, which normalizes the input of each Transformer sub-layer rather than the
  output. Specifically, it uses the RMSNorm normalization function.
* It replaces ReLU with the SwiGLU activation function to enhance performance.
* Like GPT-Neo, it omits absolute position embeddings in favor of Rotary Position Embeddings (RoPE), which improves
  performance for inference beyond the training length.

---

The MiniMind-MoE model is based on the MixFFN mixture-of-experts module from Llama3
and [DeepSeek-V2](https://arxiv.org/pdf/2405.04434).

* DeepSeek-V2 adopts more granular expert partitioning and shared expert isolation techniques in the feed-forward
  network (FFN) to improve the performance of experts.

---

The overall structure of MiniMind remains consistent, with minor adjustments in RoPE calculations, inference functions,
and FFN layer code. The structure is illustrated in the figure below (redrawn):

1. **Pretraining (Text-to-Text)**:
    - LLMs first need to absorb a vast amount of knowledge, much like filling a well with ink. The more "ink" it has,
      the better its understanding of the world will be.
    - Pretraining involves the model learning a large amount of basic knowledge from sources such as Wikipedia, news
      articles, common knowledge, books, etc.
    - It unsupervisedly compresses knowledge from vast text data into its model weights with the aim of learning word
      sequences. For instance, if we input “Qin Shi Huang is,” after extensive training, the model can predict that the
      next probable sentence is “the first emperor of China.”
   > The learning rate for pretraining is set dynamically between 1e-4 and 1e-5, with 2 epochs and a training time of
   less than one day.
    ```bash
    torchrun --nproc_per_node 2 1-pretrain.py
    ```

2. **Single Dialog Fine-Tuning**:
    - After pretraining, the semi-finished LLM has almost all language knowledge and encyclopedic common sense. At this
      stage, it only performs word sequences without understanding how to chat with humans.
    - The model needs fine-tuning to adapt to chat templates. For example, it should recognize that a template
      like “<chat start> Qin Shi Huang is <chat end>” indicates the end of a complete conversation, rather than just
      generating the next word.
    - This process is known as instruction fine-tuning, akin to teaching a knowledgeable person like Newton to adapt to
      21st-century chat habits, learning the pattern of messages on the left and responses on the right.
    - During training, MiniMind’s instruction and response lengths are truncated to 512 to save memory. Just as we start
      with shorter texts when learning, we don’t need to separately learn longer articles once we master shorter ones.
   > During inference, RoPE can be linearly interpolated to extend lengths to 1024 or 2048 or more. The learning rate is
   set dynamically between 1e-5 and 1e-6, with 5 epochs for fine-tuning.
    ```bash
    # Set dataset to sft_data_single.csv in 3-full_sft.py
    torchrun --nproc_per_node 2 3-full_sft.py
    ```

3. **Multi-Dialog Fine-Tuning**:
    - Building on step 2, the LLM has learned a single-question-to-answer chat template. Now, it only needs further
      fine-tuning on longer chat templates with historical question-and-answer pairs.
    - Use the `history_chat` field for historical dialogues and `history_chat_response` for historical responses in the
      dataset.
    - Construct new chat templates like [question->answer, question->answer, question->] and use this dataset for
      fine-tuning.
    - The trained model will not only answer the current question but also conduct coherent dialogues based on
      historical interactions.
    - This step is not strictly necessary, as small models have weak long-context dialogue abilities, and forcing
      multi-turn Q&A templates may slightly compromise single-turn SFT performance.
   > The learning rate is set dynamically between 1e-5 and 1e-6, with 2 epochs for fine-tuning.
    ```bash
    # Set dataset to sft_data.csv in 3-full_sft.py
    torchrun --nproc_per_node 2 3-full_sft.py
    ```

4. **Direct Preference Optimization (DPO)**:
    - After the previous training steps, the model has basic conversational abilities. However, we want it to align more
      closely with human preferences and provide more satisfactory responses.
    - This process is similar to workplace training for the model, where it learns from examples of excellent employees
      and negative examples to better serve customers.
   > For the Huozi trio (q, chose, reject) dataset, the learning rate is set to 1e-5, with half-precision fp16, 1 epoch,
   and it takes about 1 hour.
    ```bash
    python 5-dpo_train.py
    ```

Regarding the parameter configuration of LLMs, an interesting paper [MobileLLM](https://arxiv.org/pdf/2402.14905) has
conducted detailed research and experiments.

The scaling laws exhibit unique patterns in small models.

The parameters that cause the scaling of Transformer models almost solely depend on `d_model` and `n_layers`.

* `d_model`↑ + `n_layers`↓ -> Short and Fat
* `d_model`↓ + `n_layers`↑ -> Tall and Thin

The paper proposing the Scaling Law in 2020 suggested that the amount of training data, the number of parameters, and
the number of training iterations are the key factors determining performance, while the impact of model architecture
can be nearly ignored. However, this law does not seem to fully apply to small models.

MobileLLM proposes that the depth of the architecture is more important than its width. A "deep and narrow" model can
learn more abstract concepts compared to a "wide and shallow" model. For example, when the model parameters are fixed at
125M or 350M, a "narrow" model with 30–42 layers performs significantly better than a "short and fat" model with around
12 layers. This trend is observed across eight benchmark tests, including common-sense reasoning, question answering,
and reading comprehension.

This is a very interesting finding, as previously, almost no one attempted to stack more than 12 layers when designing
architectures for models around the 100M parameter scale.

This observation aligns with the results of MiniMind, where experiments adjusting the model parameter quantities
between `d_model` and `n_layers` during training observed similar effects. However, there is a dimensional limit to "
deep and narrow" models. When `d_model` < 512, the drawbacks of collapsing word embedding dimensions are quite
pronounced. Increasing the number of layers cannot compensate for the deficiencies in `d_head` caused by fixed `q_head`.

When `d_model` > 1536, increasing the number of layers seems to take precedence over `d_model`, providing a more "
cost-effective" parameter-to-performance gain. Therefore, MiniMind sets the `d_model` of the small model to 640
and `n_layers` to 8 to achieve a balance of "small size -> better performance". Setting `d_model` to 1024 and `n_layers`
to 16 provides greater performance gains, aligning better with the scaling-law curve for small models.

[Q]: Who proposed the law of universal gravitation?
[A]: The law of universal gravitation was proposed by British physicist Newton. He believed that all objects produce gravitational force, which is determined by the mass of the objects and their distance. This theory reveals the relationship between mass and distance and proves the nature of universal gravitation.
[B]: The law of universal gravitation was discovered by Newton and was proposed by British physicist James Watt in 1879.
[C]: Who proposed the law of universal gravitation?
[D]: The law of universal gravitation was proposed by Newton, who discovered that every object exerts a gravitational force on other objects, and the magnitude of this force depends on the mass and distance of the objects.
[E]: Gravity is a force in the universe composed of mass or energy. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to their mass and inversely proportional to their distance. Therefore, Newton's law of universal gravitation shows that the gravitational force between two objects is directly proportional to their mass and inversely proportional to their distance. This law has wide applications in physics, astronomy, and other fields.
[F]: The law of universal gravitation was proposed by British physicist Isaac Newton in 1687. He published a famous paper titled "Mathematical Principles of Natural Philosophy" in 1687, in which he proposed the law of universal gravitation, stating that there is a gravitational force between any two objects, which is directly proportional to their mass and inversely proportional to the square of their distance. This law, known as the law of universal gravitation, describes the relationship between mass and distance. It shows that the gravitational force between two objects is proportional to their mass and inversely proportional to the square of the distance between them. This law is crucial for explaining many phenomena in the universe, such as planetary motion around the sun, gravitational lensing between stars, etc. It is also widely used in astronomy, physics, and engineering, providing an important theoretical foundation for understanding the nature and evolution of the universe.

[Q]: Do you know what the main food of giant pandas is?
[A]: The main food of giant pandas is bamboo. They typically eat bamboo and need to consume about 30 kilograms of bamboo daily.
[B]: Giant pandas primarily eat bamboo. Their digestive system is quite specialized, and they need to digest a large amount of bamboo daily to meet their survival needs. Besides bamboo, giant pandas also survive in the wild.
[C]: The main food of giant pandas includes bamboo, mushrooms, beetroot, and mushrooms.
[D]: Giant pandas are herbivorous mammals that mainly eat bamboo, including bamboo shoots, bamboo leaves, and stems.
[E]: The main food of giant pandas is bamboo.
[F]: Giant pandas are herbivores whose main food is bamboo. Their digestive system is adapted to digest high-fiber bamboo, but they also eat some other plants, such as herbaceous plants and small mammals. The digestive system of giant pandas is adapted to high-fiber bamboo, which allows them to digest large amounts of cellulose, helping them survive in the wild. Additionally, giant pandas have an enzyme called "cellulase" in their digestive tract that helps them break down cellulose, aiding in the digestion of a lot of water and nutrients. Their digestive tract also contains a protein called "cellulase protein," which helps maintain their energy levels, supporting their survival in the wild. Overall, the main food of giant pandas is bamboo, but they also consume some other plants, such as herbaceous plants and small mammals.

[Q]: Why is seawater salty?
[A]: Seawater contains many salts, which can lead to an increase in the salinity of seawater. The salts in seawater primarily come from the salt content in seawater, and these salts can form hydrogen bonds with the seawater, increasing its salinity.
[B]: Seawater contains rich elements like calcium, phosphorus, potassium, and phosphorus, which are limited in quantity and distribution in the ocean. Additionally, seawater contains various nutrients from organisms and microorganisms, such as shells and seaweed.
[C]: The salinity of seawater is higher than that of seawater because of its high carbonate and base levels. The carbonate and base levels in seawater are higher than in seawater, making the seawater salty.
[D]: Seawater contains dissolved salts and other minerals, which come from the erosion and adsorption of the Earth's crust, and these substances dissolve in the water, causing the seawater to taste salty.
[E]: Water is essential for many living organisms as it can absorb and release carbon dioxide, release oxygen, maintain atmospheric water vapor, and regulate the climate and environment. The salts and chemicals in water release oxygen, which allows organisms on Earth to breathe. Additionally, water plays many other roles, such as maintaining the water cycle, regulating the climate, and supporting the environment. Water is essential for many living organisms and is also a fundamental aspect of many natural phenomena.
[F]: Seawater is salty primarily because it contains a large amount of dissolved salts, with sodium chloride (NaCl) being the most prominent. Sodium chloride is a common type of salt found in many places on Earth, including oceans, lakes, rivers, and groundwater. When water evaporates from the ocean, it carries away some of the salts, making the seawater salty. Additionally, seawater contains other dissolved salts, such as sulfate, magnesium sulfate, calcium sulfate, and potassium sulfate.

### 👉 Summary of Results

* The ranking of the minimind series (ABCD) is intuitive. minimind(0.2B) scores the highest, with minimal errors and
  hallucinations in answering common-sense questions.
    * Surprisingly, minimind-small-T (0.02B) with only 26M parameters performs close to minimind(0.2B).
    * minimind(0.2B) had less than 2 epochs of SFT training. Despite the training time being several times that of
      0.02B, the model was terminated early to free up resources for smaller models. Even with insufficient training,
      0.2B achieved the best performance, highlighting the impact of model size.
    * minimind-MoE (0.16B) performed poorly, even worse than its dense counterpart minimind(0.05B). This isn't due to
      the MoE approach itself but rather because the model was terminated early due to resource constraints. MoE models
      typically require more training epochs, and with only 2 epochs, the training was extremely insufficient. A
      well-trained MoE version was previously tested on Yi tokenizer and showed visibly better performance compared to
      dense models. Further training for updates to v2 and v3 versions will be conducted when server resources are
      available.

* Model F's responses appear the most complete, despite some hallucinations. Both GPT-4o and Kimi's evaluations agree
  that it is "overly verbose with repetitive content and contains hallucinations." This evaluation may seem too
  harsh—hallucinations accounting for 10 out of 100 words can unfairly lead to a 0 score. Model F, having a default
  longer training text and a much larger dataset, provides seemingly more complete answers, with data proving more
  crucial than model size in similar contexts.

> 🙋‍♂️ Personal subjective rating: F > D > A ≈ B > C > E

> 🤖 GPT-4o rating: D > A > B > F > C > E

In summary, the scaling law suggests that larger model parameters and more training data generally lead to stronger
model performance.

# 📌 Objective Dataset: C-Eval

C-Eval evaluation code is located at: `./eval_ceval.py`.

For small models, to avoid issues with fixed response formatting, we directly judge the prediction probabilities of the
four tokens `A`, `B`, `C`, `D`, and choose the one with the highest probability as the answer, then calculate accuracy
against the standard answer. Note that minimind models were not trained on larger datasets or fine-tuned for question
answering, so results should be considered as reference only.

3. **Education Science**: The model shows good performance in education-related topics with a 37.93% accuracy.
4. **Basic Medicine**: The accuracy of 36.84% indicates strong performance in foundational medical knowledge.
5. **Operating Systems**: With a 36.84% accuracy, the model demonstrates reliable performance in computer operating systems.

### Areas Where the Model Struggles:
1. **Legal Topics**: The model performs poorly in legal-related areas such as Legal Professional (8.70%) and Tax Accountant (20.41%).
2. **Physics**: Both high school (26.32%) and college-level (21.05%) physics topics are challenging for the model.
3. **High School Politics and Geography**: The model shows low accuracy in these areas, with High School Politics at 15.79% and High School Geography at 21.05%.
4. **Computer Networking and Architecture**: The model struggles with Computer Networking (21.05%) and Computer Architecture (9.52%).
5. **Environmental Impact Assessment Engineering**: The accuracy is only 12.90%, indicating weak performance in environmental science.

### Summary:
- **Strengths**: Chemistry, Mathematics (especially Discrete Mathematics), Education Science, Basic Medicine, and Operating Systems.
- **Weaknesses**: Legal Topics, Physics, Politics, Geography, Computer Networking and Architecture, and Environmental Science.

This suggests that the model performs well in logical reasoning, foundational sciences, and some engineering disciplines but is weaker in humanities, social sciences, and certain specialized fields (such as law and taxation).
