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!
