## Introduction
Leveraging multimodal data to drive breakthroughs in e-commerce applications through Multimodal Foundation Models (MFMs) is gaining increasing attention. This work introduces [MMECInstruct](https://huggingface.co/datasets/NingLab/MMECInstruct), the first-ever, large-scale, and high-quality multimodal instruction dataset for e-commerce. We also develop CASLIE, a simple, lightweight, yet effective framework for integrating multimodal information for e-commerce. Leveraging MMECInstruct, we fine-tune a series of e-commerce MFMs within CASLIE, denoted as CASLIE models.
## CASLIE Models
The CASLIE-L model is instruction-tuned from the large base model [Llama-2-13b-chat](https://huggingface.co/meta-llama/Llama-2-13b-chat-hf).
## Sample Usage (Modality-unified Inference)
To conduct inference with the CASLIE models, refer to the following example directly from the [official GitHub repository](https://github.com/ninglab/CASLIE#modality-unified-inference).
`$model_path` is the path of the instruction-tuned model.
`$task` specifies the task to be tested.
`$output_path` specifies the path where you want to save the inference output.
Example:
```
python inference.py --model_path NingLab/CASLIE-M --task answerability_prediction --output_path ap.json
```
