Quickstart

Build and run your first Pie inferlet in just a few minutes.

Step 1: Install Pie

First, install the Pie server and client:

pip install pie-client

Step 2: Create an Inferlet

Create a new Rust project:

cargo new my-first-inferlet
cd my-first-inferlet

Add the inferlet SDK dependency in Cargo.toml:

[dependencies]
inferlet = "0.1"

Write your inferlet in src/main.rs:

use inferlet::{Args, Result, Sampler, get_auto_model};
use inferlet::stop_condition::max_len;
 
#[inferlet::main]
async fn main(mut args: Args) -> Result<String> {
    let model = get_auto_model();
    let mut ctx = model.create_context();
 
    let prompt = args.get("prompt").unwrap_or("Hello!");
    ctx.fill_user(prompt);
 
    let sampler = Sampler::top_p(0.6, 0.95);
    let stop = max_len(50);
 
    let response = ctx.generate(sampler, stop).await;
    Ok(response)
}

Step 3: Build to WebAssembly

cargo build --target wasm32-wasi --release

Step 4: Run Your Inferlet

pie run ./target/wasm32-wasi/release/my-first-inferlet.wasm -- --prompt "Tell me a joke"
