• Paper: [https://arxiv.org/abs/2404.02406]

Uses

The use of this model should comply with the restrictions from TinyLlama-1.1b and Stanford Alpaca.

How to Get Started with the Model

Use the code below to get started with the model.

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("luckychao/TinyAlpaca-1.1B")
model = AutoModelForCausalLM.from_pretrained("luckychao/TinyAlpaca-1.1B")

Training Details

Training Data

We use the alpaca dataset, which is created by researchers from Stanford University.

Training Procedure

We follow the same training procedure and mostly same hyper-parameters to fine-tune the original Alpaca model on Llama. The procedure can be found in stanford_alpaca project.
