# 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 workNext-generation intelligence for long-running agents. Read the [Claude Fable 5 and Claude Mythos 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 reasonFor complex agentic coding and agentic codingerprise work. Read the [Claude Opus 4.8 announcement](https://www.anthropic.com/news/claude-opus-4-8).¶

**Claude Sonnet 5** - Frontier intelligence at scale, built for coding, agents, and enterprise workflows. Read the [Claude Sonnet 5 announcement](https://www.anthropic.com/news/claude-sonnet-5).¶

**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 |¶
| -------------- | --------------------------------------------------------------------- | ------------------------------------------------------------------------- |¶
| **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) |¶
