Overview

Dexto gives you two ways to build AI agents. Pick the approach that fits your needs.

Two Ways to Build

CLI & Configuration

Build agents with YAML configuration files. No code required.

# my-agent.yml
systemPrompt: You are a helpful assistant.
llm:
  provider: openai
  model: gpt-5-mini
  apiKey: $OPENAI_API_KEY

dexto --agent my-agent.yml

Best for: Quick prototypes, simple agents, config-driven workflows

→ Get started with CLI & Configuration

---

Dexto Agent SDK

Build agents programmatically with TypeScript. Full control over behavior and integration.

import { DextoAgent } from '@dexto/core';

const agent = new DextoAgent({
  llm: { provider: 'openai', model: 'gpt-5-mini', apiKey: process.env.OPENAI_API_KEY }
});

await agent.start();
const session = await agent.createSession();
const response = await agent.generate('Hello!', session.id);

Best for: Custom apps, production systems, complex integrations

→ Get started with the Dexto Agent SDK
