Research direction

Investigate how existing models (e.g., Vicuna, Llama) are registered and loaded in FastChat. Look at the model registry files such as fastchat/model/model registry.py and fastchat/model/model adapter.py. Identify the necessary files to add support for phi 1.5, including tokenizer and model configuration. Review any existing discussions in the issue comments for specific implementation details or blockers.
