Fast Multimodal LLM on Mobile Devices

Primary LanguageC++MIT LicenseMIT

Website Documentation Actions Status

mllm is 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

Wait.. why on-device multimodal LLM? - It's a key building block for intelligent personal agent, text-based image searching/retrieval, screen VQA, and many more exciting mobile apps, without giving away your private data (chat history, screenshots, taken photos, etc).

[Q]  Hello, who are you?
[A]

I am a bot, I'm here to help answer your questions and provide information. I'm just an AI, I don't have personal experiences or feelings like humans do, but I'm here to help you with any questions you may have. Is there something specific you would like to know or talk about?
[Q]  What can you do?
[A]
I can help with a wide range of tasks, including:
  
* Answering questions on various topics, such as science, history, technology, and more.
* Providing information on different subjects, such as culture, entertainment, and lifestyle.
* Helping with language-related tasks, such as translating text or improving grammar and syntax.
* Generating text, such as articles, stories, or even entire books.
* Assisting with coding
[Q]  Please introduce Beijing University of Posts and Telecommunications.

Customization

Convert models

You can download models from here, or you can convert a pytorch/safetensor model to mllm model by yourself.

cd tools/convertor
pip install -r ./requirements.txt

# for one file pytorch model
python converter.py --input_model=model.pth --output_model=model.mllm --type=torch

# for multi-file pytorch model
python converter.py --input_model=pytorch_model.bin.index.json --output_model=model.mllm --type=torch

# for one file safetensor model
python converter.py --input_model=model.bin --output_model=model.mllm --type=safetensor

# for multi-file safetensor model
python converter.py --input_model=model.safetensors.index.json --output_model=model.mllm --type=safetensor

Convert vocabulary

You can convert vocabulary to mllm vocabulary as followed.

cd tools/convertor
python vocab.py --input_file=tokenizer.json --output_file=vocab.mllm --type=Unigram

Quantize models

You can quantize mllm model to int4 model by yourself. mllm only support two quantize modes: Q4_0 and Q4_K.

cd bin
./quantize model.mllm model_q4_k.mllm Q4_K

Roadmap

  • More backends like QNN
  • More models like PandaGPT
  • More optimizations like LUT-GEMM
  • More..
