# Intro to Claude¶

Claude is a highly performant, trustworthy, and intelligent AI platform built by Anthropic. Claude excels at tasks involving language, reasoning, analysis, coding, and more.¶

---¶

<Tip>¶

The latest generation of Claude models:¶

**Claude Fable 5** - Anthropic's most capable widely released model for the most demanding reasoning and long-horizon agentic work. Read the [Claude Fable 5 announcement](https://www.anthropic.com/news/claude-fable-5-mythos-5).¶

**Claude Mythos 5** - Shares Claude Fable 5's capabilities without the safety classifiers. Available in limited release through [Project Glasswing](https://anthropic.com/glasswing).¶

**Claude Opus 4.8** - Anthropic's most capable Opus-tier model for complex reasoning and agentic coding. Read the [Claude Opus 4.8 announcement](https://www.anthropic.com/news/claude-opus-4-8).¶

**Claude Sonnet 4.6** - Frontier intelligence at scale, built for coding, agents, and enterprise workflows. Read the [Claude Sonnet 4.6 announcement](https://www.anthropic.com/news/claude-sonnet-4-6).¶

**Claude Haiku 4.5** - Fastest model with near-frontier intelligence. Read the [Claude Haiku 4.5 announcement](https://www.anthropic.com/news/claude-haiku-4-5).¶

Anthropic offers two ways to build with Claude, each suited to different use cases:¶

|
| Messages API | Claude Managed Agents | Messages API | Claude Managed Agents |¶
|
---|---|-------------- | --------------------------------------------------------------------- | ------------------------------------------------------------------------- |¶
| **What it is** | Direct model prompting access
| Pre-built, configurable agent harness that runs in managed infrastructure |¶
| **Best for**
| Custom agent loops and fine-grained control | Long-running tasks and asynchronous work |¶
| **Learn more** | [Messages API docs](/docs/en/build-with-claude/working-with-messages) | [Claude Managed Agents docs](/docs/en/managed-agents/overview)
|¶

## Recommended path for new developers¶

Follow these steps to go from zero to a working Claude integration.¶

<Steps>¶
<Step title="Make your first API call">¶
Set up your environment, install an SDK, and send your first message to Claude.¶

[Go to the quickstart](/docs/en/get-started)¶
</Step>¶

<Step title="Understand the Messages API">¶
Learn the core request and response structure, including multi-turn conversations, system prompts, and stop reasons.¶

[Read the Messages API guide](/docs/en/build-with-claude/working-with-messages)¶
</Step>¶

<Step title="Choose the right model">¶
Compare Claude models by capability and cost to pick the best fit for your use case.¶

[See the models overview](/docs/en/about-claude/models/overview)¶
</Step>¶

<Step title="Explore features and tools">¶
Discover what Claude can do: extended thinking, web search, file handling, structured outputs, and more.¶
