| Taiwan-LLaMa is a fine-tuned model specifically designed for traditional Chinese 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 Chinese. | |
| ## Key Features | |
| 1. **Traditional Chinese Support**: The model is fine-tuned to understand and generate text in Traditional Chinese, 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-LLaMa v1.0 (This demo)**: Optimized for Taiwanese Culture | |
| - **Taiwan-LLaMa v0.9**: Partial instruction set | |
| - **Taiwan-LLaMa v0.0**: No Traditional Chinese 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 Chinese! | |
