+
+YuLan-Mini is a lightweight language model with 2.4 billion parameters. It achieves performance comparable to industry-leading models trained on significantly more data, despite being pre-trained on only 1.08T tokens. The model excels particularly in the domains of **mathematics** and **code**. To facilitate reproducibility, we will open-source the relevant [pre-training resources](https://github.com/RUC-GSAI/YuLan-Mini/tree/main/pretrain).

+## Features 🌟
+
+<div align=center>
+<img src="assets/main.png">
+</div>
+
+Our pre-training methodology improves training efficiency through three key innovations:
+
+1. an elaborately designed **data pipeline** that combines data cleaning with data schedule strategies;
+2. a systematic **optimization method** that can effectively mitigate training instability;
+3. an effective **annealing approach** that integrate targeted data selection and long context training.

+\*: For easier inference and deployment, we merged the re-parameterized added parameters and scaling factors into the final released models ([**YuLan-Mini**](https://huggingface.co/yulan-team/YuLan-Mini) and **YuLan-Mini-Intermediate-4K**), enabling it to run on the Llama architecture. However, these parameters are still retained in the intermediate checkpoints from the training process.

+### What you can do with these pre-training resources
+
+1. **Pre-train** your own LLM. You can use [our data](https://huggingface.co/yulan-team/YuLan-Mini-Datasets) and curriculum to train a model that's just as powerful as YuLan-Mini.
+2. Perform your own **learning rate annealing**. During the annealing phase, YuLan-Mini's learning ability is at its peak. You can resume training from [the checkpoint before annealing](https://huggingface.co/yulan-team/YuLan-Mini-Before-Annealing) and use your own dataset for learning rate annealing.
+3. **Fine-tune** the Instruct version of the LLM. You can use the [YuLan-Mini](https://huggingface.co/yulan-team/YuLan-Mini) base model to train your own Instruct version.
+4. **Training dynamics** research. You can use YuLan-Mini's [intermediate checkpoints](https://huggingface.co/collections/yulan-team/yulan-mini-676d214b24376739b00d95f3) to explore internal changes during the pre-training process.
+5. **Synthesize** your own data. You can use YuLan-Mini's [data pipeline](https://github.com/RUC-GSAI/YuLan-Mini) to clean and generate your own dataset.

+
+## Quick Start 💻
+
+Below is a simple example for inference using Huggingface:
+
+**Huggingface Inference Example**
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+# Load model and tokenizer
+tokenizer = AutoTokenizer.from_pretrained("yulan-team/YuLan-Mini")
+model = AutoModelForCausalLM.from_pretrained("yulan-team/YuLan-Mini", torch_dtype=torch.bfloat16)
+
+# Input text
+input_text = "Renmin University of China is"
+inputs = tokenizer(input_text, return_tensors="pt")
+
+# Completion
+output = model.generate(inputs["input_ids"], max_new_tokens=100)
+print(tokenizer.decode(output[0], skip_special_tokens=True))
+```
+
+**vLLM Serve Example**
+```bash
+vllm serve yulan-team/YuLan-Mini --dtype bfloat16
+```
+
+**SGLang Serve Example**
+```bash
+python -m sglang.launch_server --model-path yulan-team/YuLan-Mini --port 30000 --host 0.0.0.0
+```
