The front door to Hanzo AI
Hanzo Chat is where you talk to the Hanzo AI cloud. Open a thread to reach the Zen model family and other frontier models through one API — switch models mid-conversation, or let Enso route each turn to the best fit — then build agents, connect MCP tools, chat over your files, search the web, run code, and generate images, all in the same conversation.
Open source (Apache-2.0). Sign in with your Hanzo account, or self-host the whole stack.
Chat with the whole Hanzo cloud
One place to pick a model, attach your tools and files, and keep the entire conversation — signed in with your Hanzo account, or self-hosted from the open-source release.
Every model, one thread
Reach the Zen model family and other frontier models through a single Hanzo API. Switch models mid-conversation, or let Enso route each turn to the best-fit model.
Agents and tools
Build an agent right in the thread, or run your Hanzo Cloud agents with an /agent command or an @mention. Connect Model Context Protocol servers so a model can call your tools.
Grounded, not guessing
Chat over your own files, search the web through Hanzo’s own backend, and run code in a sandbox — so answers come from real sources, not guesswork.
One chat, every capability
Enso routing by default
New chats default to Enso, which routes each turn to the best-fit model — easy turns stay cheap, hard ones escalate.
MCP tools
Connect Model Context Protocol servers and let a model call your tools, APIs, and data.
Code interpreter
Run code in a sandboxed runtime and get results back inline, without leaving the thread.
Chat over your files
Upload images, PDFs, and text, then ask questions across everything you’ve attached.
Grounded web search
Answers backed by Hanzo’s own search backend — no third-party search service in the loop.
Image generation
Generate images inline, in the same conversation you’re already working in.
Open a thread
Pick a model, attach your tools and files, and start chatting on hanzo.chat — or self-host the open-source stack.
