Branch, loop, and run work in parallel

You keep important branches, loops, and parallel work under application control. The model handles typed steps instead of improvising the orchestration plan.

let mermaid = r#"flowchart TD
  %%ax classify: request:string -> route:class "support, sales"

println!("{}", program);

Run itIn your own project

cargo add axllm

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

fn main() -> AxResult<()> {
    let mut llm = ai("openai", json!({"apiKey": std::env::var("OPENAI_API_KEY")?}))?;
    let mut classify = ax("review:string -> sentiment:class \"positive, negative, neutral\"")?;
    let result = classify.forward(&mut llm, json!({
        "review": "Useful and boring in the best way."
    }))?;

    println!("sentiment: {}", result["sentiment"].as_str().unwrap_or_default());
    Ok(())
}

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