What it is
Run highly optimized machine learning on small devices, like phones or robots, using MNN.
What you can make with it
Automations like: on a custom robot, use MNN to recognize objects and adjust its behavior.
How it helps
MNN helps you create fast and accurate AI on devices that can't rely on big cloud services, saving power and memory.
Real use case example
"A founder of a robotics startup wants to create a self-driving wheelchair. First, they connect a camera to their prototype. Then, they write code that uses MNN to detect obstacles and adapt the path. Finally, they test the device in different environments, refining its AI."
If you're new
When you're new to AI development and want to get started with on-device machine learning.
If you're senior
When you need a high-performance, lightweight AI engine for your custom robotics or IoT project.
Common confusion cleared up
MNN doesn't require complex setup or prior AI expertise; its pre-built functions make it relatively easy to integrate into your project.

Why we list it on WorkflowStacks: The marketplace includes MNN because it's a popular, battle-tested AI engine that's free and open-source.
What it does
MNN is a high-performance, lightweight inference engine for on-device AI and Edge AI applications, allowing for fast and efficient model deployment
Install / run
git clone https://github.com/alibaba/MNN.git
When to use it
โขWhen you need to deploy AI models on edge devices with limited computational resources
โขWhen you want to improve the performance and efficiency of your on-device AI applications
โขWhen you need a battle-tested and widely adopted inference engine for your startup's AI projects
Quick start
1Build the MNN library by running the command 'cmake . && make' in the MNN repository
2Create a new C++ project and include the MNN library by adding 'include/mnn.h' to your includes
3Load a pre-trained model using the 'mnn::Interpreter' class and 'mnn::Session' class
4Use the 'mnn::Session::run' function to run the model and get the output
5Check the example code in the 'examples' directory of the MNN repository for a complete example
Heads up: MNN requires a compatible C++ compiler (e.g. GCC 5.4 or later) and a compatible OpenCV version (e.g. OpenCV 3.4 or later) to build and run successfully
