+# GPT-Thai-Think 🤖
+
+A Thai-centric GPT-2 model with **thinking and reasoning capabilities**! This model can engage in conversations and solve problems while showing its step-by-step reasoning process.
+
+## 🌟 Key Features
+
+- **Thai Language Support**: Optimized for Thai text processing
+- **Thinking Capabilities**: Shows step-by-step reasoning with `<think>` tags
+- **Conversational AI**: Handles instruction-response conversations
+- **Mathematical Reasoning**: Solves math problems with calculation steps
+- **Bilingual**: Supports both Thai and English
+
+## 📊 Model Details
+
+- **Model Size**: 8.1M parameters
+- **Architecture**: GPT-2 with 4 layers, 256 embedding dimension
+- **Vocabulary**: 19,000 tokens (Thai-optimized)
+- **Training Data**:
+  - 10,029 Thai conversation pairs
+  - 25,000 reasoning examples from HelpingAI dataset
+- **Training**: 3 epochs with final loss 2.4
+
+## 🚀 Usage
+
+### Basic Usage
+```python
+from transformers import GPT2LMHeadModel, GPT2Tokenizer
+
+model = GPT2LMHeadModel.from_pretrained("your-username/gpt-thai-think")
+tokenizer = GPT2Tokenizer.from_pretrained("your-username/gpt-thai-think")
+
+# Generate text
+prompt = "คำสั่ง: สวัสดีครับ
+คำตอบ:"
+inputs = tokenizer(prompt, return_tensors="pt")
+outputs = model.generate(**inputs, max_length=100)
+response = tokenizer.decode(outputs[0])
+```
+
+### With Thinking
+```python
+# The model shows reasoning steps
+prompt = "Question: What is 15% of 200?
+"
+inputs = tokenizer(prompt, return_tensors="pt")
+outputs = model.generate(**inputs, max_length=150)
+response = tokenizer.decode(outputs[0])
+# Response includes <think> tags with reasoning steps
+```
+
+## 💡 Example Outputs
+
+### Math Problem
+```
+Question: If a train travels 120 km in 2 hours, what is its average speed?
+<think>
+To find average speed, I need to divide distance by time.
+Distance = 120 km, Time = 2 hours
+Speed = Distance ÷ Time = 120 km ÷ 2 hours = 60 km/h
+</think>
+Final Answer: 60 km/h
+```
+
+### Thai Conversation
+```
+คำสั่ง: สวัสดีครับ
+คำตอบ: สวัสดีครับ ยินดีที่ได้คุยกันครับ
+```
