Strands Agents - A Rust AI Agents SDK

Strands is a model-agnostic SDK for building AI agents.

Quick Start

use strands_agents::{Agent, AgentBuilder};
use strands_agents::models::BedrockModel;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut agent = Agent::builder()
        .model(BedrockModel::new("anthropic.claude-3-sonnet-20240229-v1:0"))
        .system_prompt("You are a helpful assistant")
        .build()?;
     
    let result = agent.invoke_async("Hello!").await?;
    println!("{}", result);
    Ok(())
}
