+#  LightWeight Deepseek R1 (2 Hidden Layers Version with Smaller Dimensions)
+
+This project is created using the official **Deepseek R1** model script (`modeling_deepseek.py`) from [Hugging Face](https://huggingface.co/deepseek-ai/DeepSeek-R1/blob/main/modeling_deepseek.py). It implements a **2-layer version** of Deepseek R1 with randomly initialized weights and smaller dimensions.
+
+## Model Structure
+The three hidden layers consist of:
+- **A hidden layer: MLA + Dense MLP**
+- **A hidden layer: MLA + MoE (Mixture of Experts) MLP**
+
+The difference between this model and the original **Deepseek R1** is shown below:
+```json
+{
+	"first_k_dense_replace": 1,
+	"intermediate_size": 1024,
+	"n_routed_experts": 64,
+	"num_experts_per_tok": 4,
+	"moe_intermediate_size": 128,
+	"num_hidden_layers": 2,
+	"num_nextn_predict_layers": 0
+}
+```
+
+## Purpose
+The purpose of these weights is to provide a lightweight implementation for researchers who want to study the model architecture and run experiments quickly.
+
+The original **Deepseek R1 model** requires an **8x H200 GPU setup** and runs on the **vLLM/SGLang framework**, making it difficult to deploy on standard hardware.
+
+## Usage
+
+```python
+from transformers import AutoConfig, AutoModelForCausalLM
+from transformers import AutoTokenizer
+import torch
+
+model = AutoModelForCausalLM.from_pretrained('silence09/DeepSeek-R1-Small-2layers', torch_dtype=torch.bfloat16).cuda()
+tokenizer = AutoTokenizer.from_pretrained('silence09/DeepSeek-R1-Small-2layers')
+
+prompt = "Who are u?"
+messages = []
+messages.append({"role": "user", "content": prompt})
+prompt_tokens = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
+generated_ids = model.generate(prompt_tokens, max_new_tokens=100, do_sample=False)
+generated_ids = [
+    output_ids[len(input_ids):] for input_ids, output_ids in zip(prompt_tokens, generated_ids)
+]
+completion = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
+print(completion)
+messages.append({"role": "assistant", "content": completion})
+
+```
+
+## More Info
+It was created using the python script available at [this repository](https://github.com/silencelamb/naked_llama/blob/main/hf_example/create_deepseek_r1_small_2layers.py)
