PKU-Alignment/alpaca-7b-reproduced: An Instruction-Following LLaMA Model

This model is a 7 billion parameter instruction-following language model developed by the PKU-Alignment Team. It is a reproduced version of the original Stanford Alpaca model, built upon the LLaMA foundation model.

Key Characteristics & Differences

• Foundation Model: Fine-tuned from Meta's LLaMA architecture.
• Reproduction: This is a re-implementation of the Stanford Alpaca model, not the original.
• Training Backend: Utilizes the DeepSpeed library for training, differing from the original's PyTorch FSDP.
• Conversation Template: Employs a distinct conversation template compared to the original Stanford Alpaca.
• License: Distributed under a non-commercial license.

Usage & Evaluation

Users can interact with the model via the PKU-Alignment/safe-rlhf library's interactive CLI demo or through the Hugging Face Transformers library. Evaluation results for this model are detailed in the associated paper: https://arxiv.org/abs/2310.12773.

Good for

• Experimenting with instruction-following capabilities based on the LLaMA architecture.
• Research into different training methodologies (DeepSpeed) for instruction-tuned models.
• Understanding variations in Alpaca model implementations and their conversational behaviors.
