See the idea in context

let step = ax("request:string -> route:class \"support, sales, engineering\"")?;
let program = flow("supportRouter")
    .execute("classify", step)
    .returns(json!({"route": "classify"}));

Run itIn your own project

cargo add axllm

use axllm::{ai, ax};
use serde_json::json;

let llm = ai("openai", json!({"apiKey": std::env::var("OPENAI_API_KEY")?}))?;
let classify = ax("review:string -> sentiment:class \"positive, negative, neutral\"")?;

Set OPENAI_APIKEY in your environment before running provider-backed code.
