Muna compiles stateless Python functions into self-contained executable binaries.
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

Write your function, add a docstring, then wrap it with our @compile decorator:
greeting.py
from muna import compile

@compile()
def greeting(name: str) -> str:
    """
    Say a friendly greeting.
    """
    return f"Hey there {name}! We're glad you're using Muna and we hope you like it."
The docstring is used as a description, is required, and must be 100 characters or less.
The 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 function
$ 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:

​
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 function 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.
