The architecture of our proposed M4, a one-size-fits-all foundation model
for diversified mobile/edge-oriented AI tasks. It is designed with the following principles:
- unified: instead of building independent foundation models for different possible modalities, M4 provides a unified architecture that maximizes the capability sharing across different modalities, thus being more resource-efficient and extensible;
- elastic: M4 can be easily scaled out to more modalities (either for input or output), e.g., for new types of sensor/app data;
- multimodal: M4 can take multimodal input or generate multimodal output as needed, e.g., for advanced mobile applications like visual question answering or audio caption.
The inference code for M4 on 50 tasks is stored in the code/infer directory. It is organized based on the underlying model into three folders: path1, path2, and path3. Each folder contains detailed instructions, dependencies, and code for the inference of each task. Pretrained weights for each task are stored in the pretrained_ckpt path.
Task Index
| Path | Task |
|---|---|
| code/infer/path3 | T14, T15, T16, T18, ..., T31, T35, T36, T38, T39, T40, T46, T47, T48 |
| code/infer/path2 | T1, T2, T3, ..., T13 |
| code/infer/path1 | T32, T33, T34, T37, T42, ..., T45, T49, T50 |
Demo Example
We use the Task-21 Optical Character Recognition as an example to demonstrate the inference process of M4.
cd code/infer/Path-3
To install the required environment, please run
conda create --name path3 python=3.8 -y
conda activate path3
pip install -r requirements.txt
Task-21 optical character recognition uses Rendered SST2 dataset.
python t21-rendered.py
The inference code for eAIBench, a comprehensive edge-oriented benchmark for AI tasks, is stored in the code/Benchmark directory. It is organized based on the underlying tasks or frameworks. Each folder contains detailed instructions, dependencies, and code for the inference of each task. Pretrained weights for each task are stored in the pretrained_ckpt path.
Demo Example
We use the Task-1 Input Word Prediction as an example to demonstrate the inference process of eAIBench.
cd code/Benchmark
Install the Pytorch package with the correct cuda version, for example
pip install torch==1.13.1+cu117 -f https://download.pytorch.org/whl/torch/Task-1 Input Word Prediction inference uses PTB dataset, and we already put it in [./WordPrediction/penn] directory.
cd MobileFM/code/Benchmark/WordPrediction
python test.pyTo support the mobile deployment of M4, our team further developed mllm, a fast and lightweight multimodal LLM inference engine for mobile and edge devices.
- Plain C/C++ implementation without dependencies
- Optimized for multimodal LLMs like fuyu-8B
- Supported: ARM NEON and x86 AVX2
- 4-bit and 6-bit integer quantization
cd code/mobile
Additional code for this project will be made available in the repository shortly. To facilitate understanding of the project, we have pre-created a file tree for the entire project. The training code will be uploaded to the code/train path, and the parameters for model training will be uploaded in YAML format to the code/configs path.
