# 🌟 Checkout New [Taiwan-LLM UI](http://www.twllm.com) 🌟 Taiwan-LLaMa is a fine-tuned model specifically designed for traditional mandarin applications. It is built upon the LLaMa 2 architecture and includes a pretraining phase with over 5 billion tokens and fine-tuning with over 490k multi-turn conversational data in Traditional Mandarin. ## Key Features 1. **Traditional Mandarin Support**: The model is fine-tuned to understand and generate text in Traditional Mandarin, making it suitable for Taiwanese culture and related applications. 2. **Instruction-Tuned**: Further fine-tuned on conversational data to offer context-aware and instruction-following responses. 3. **Performance on Vicuna Benchmark**: Taiwan-LLaMa's relative performance on Vicuna Benchmark is measured against models like GPT-4 and ChatGPT. It's particularly optimized for Taiwanese culture. 4. **Flexible Customization**: Advanced options for controlling the model's behavior like system prompt, temperature, top-p, and top-k are available in the demo. ## Model Versions Different versions of Taiwan-LLaMa are available: - **Taiwan-LLM v2.0 (This demo)**: Cleaner pretraining, Better post-training - **Taiwan-LLM v1.0**: Optimized for Taiwanese Culture - **Taiwan-LLM v0.9**: Partial instruction set - **Taiwan-LLM v0.0**: No Traditional Mandarin pretraining The models can be accessed from the provided links in the Hugging Face repository. Try out the demo to interact with Taiwan-LLaMa and experience its capabilities in handling Traditional Mandarin!
