Muna compiles stateless Python functions into self-contained binaries we call predictors.
Your Python code is lowered directly to native code, and does not rely on the Python runtime (or any other managed runtime).

​
Defining a Function

To define a prediction function, wrap a Python function with the @compile decorator, providing a predictor tag and short description:
greeting.py
from muna import compile

@compile(
    tag="@your-username/greeting", # replace `your-username` with your Muna username
    description="Say a friendly greeting."
)
def greeting(name: str) -> str:
    return f"Hey there {name}! We're glad you're using Muna and we hope you like it."
The predictor description is required and must be 100 characters or less.
The prediction function must specify parameter and return type annotations. Learn more.

​
Compiling the Function

Use the Muna CLI to compile the function. First, make sure you are logged into the Muna CLI: 
# Login to the CLI
$ muna auth login <access key>
Then run the following command: 
# Compile the predictor
$ muna compile --overwrite greeting.py
Muna will upload your code, perform code generation on your function and its dependencies, then compile for our supported platforms:

Creating a predictor with the Muna CLI. This is realtime--not sped up.

​
Using the Function

Depending on the complexity of your function, it can take anywhere from a few seconds to a few minutes for the function to be compiled for all platforms. Once the function is compiled, you can run it everywhere: 
import { Muna } from "muna"

// 💥 Create your Muna client
const muna = new Muna({ accessKey: "..." });

// 🔥 Make a prediction
const prediction = await muna.predictions.create({
    tag: "@your-username/greeting",
    inputs: { name: "Lina" }
});

// 🚀 Print the result
console.log(prediction.results[0]);
You can check the compilation status of the predictor at muna.ai/predictors.
Muna currently takes longer to compile functions for macOS, iOS, and visionOS due to limited Mac compilation server capacity. We are working to provision more servers.

​
Try it Out

We have an open-source Playground project that shows the full workflow from writing and compiling a Python function; to using it across the following platforms:
  • React with Next.js (Browser, Node.js)
  • React Native with Expo (Android, iOS)
  • Kotlin in Android Studio (Android)
  • Swift in Xcode (iOS)
  • Python (Linux, macOS, Windows)
  • Unity Engine (Android, iOS, Linux, macOS, visionOS, WebGL, Windows)

Compile a Python function and run it cross-platform.
