Try Hanzo
Playground

Where to start

Six ways into Hanzo, and what each one is actually for. Some are a page you read, some are a command you run. None of them need a sales call first.

Paste and ship

Paste this into any agent. It reads the skill manifest and calls Playground from there.

Zen models

The family we train ourselves — 0.6B you can run on a laptop up to frontier. Most are open weight; read the specs and the price per million tokens.

See the models

Bot

Bots as backend services: routing, async runs that last hours, durable state, and an identity per bot instead of a shared key.

Read about Bot

MCP

Thirteen tools — shell, files, code, git, HTTP — behind one server. One block in .mcp.json and your client has them.

Set up MCP

Hanzo Dev

A coding agent in your terminal. It opens the files, makes the change, runs the tests, and shows you the diff.

Install Dev

Chat

One thread with every model, your MCP tools, your files and a code sandbox. The first two questions need no account.

Open Chat

Agents

A Python SDK where an agent is a model, instructions and tools — and several of them can sit behind one router.

Or copy-paste a starter

A key, a model name, and a message is the whole first request.
