Overview

<Tip> **elizaOS** — the open agentic operating system (AIOS). Three commands. Runs anywhere. </Tip>

Build agents in your language

elizaOS ships TypeScript, Python, and Rust with identical APIs. Pick one. Start in minutes.

Create, then run project scripts

Why elizaOS?

Eliza agents can trade onchain, manage social media, create content, analyze data, or talk to any API, blockchain, or repository.

API consistency across languages

All three implementations share identical interfaces:

Operation	TypeScript	Python	Rust
Create runtime	new AgentRuntime({...})	AgentRuntime(...)	AgentRuntime::new(...)
Initialize	await runtime.initialize()	await runtime.initialize()	runtime.initialize().await
Use model	runtime.useModel(type, params)	runtime.use_model(type, params)	runtime.use_model(type, params).await
Handle message	messageService.handleMessage(...)	message_service.handle_message(...)	message_service().handle_message(...)
Stop	await runtime.stop()	await runtime.stop()	runtime.stop().await

Quick example

<Tabs> <Tab title="TypeScript"> ```typescript import { AgentRuntime } from '@elizaos/core'; import { openaiPlugin } from '@elizaos/plugin-openai'; import { plugin as sqlPlugin } from '@elizaos/plugin-sql';

const runtime = new AgentRuntime({ character: { name: 'Eliza', bio: 'An Eliza agent.', }, plugins: [sqlPlugin, openaiPlugin], });

await runtime.initialize(); console.log('Agent is ready!');

</Tab> <Tab title="Rust"> ```rust use elizaos::{AgentRuntime, RuntimeOptions, parse_character}; use elizaos_plugin_openai::create_openai_plugin;

#[tokio::main] async fn main() -> anyhow::Result<()> { let character = parse_character(r#"{ "name": "Eliza", "bio": "An Eliza agent." }"#)?;

}
