Frontier models, agents, and the cloud under them.
Chat, build and ship on one API — models, Base backends, identity, secrets and vector search. The same code runs on your own hardware.
Run it on your own machine
Most AI platforms hand you an API key. We hand you the platform. One binary, and hanzo serve brings up the cloud itself — control plane, identity, secrets, gateway, storage, pub/sub — on your own hardware.
It is the same code we run in our own cloud, under an open licence. Point a client at localhost or at api.hanzo.ai — same API, nothing else changes.

The whole stack as an app. The agent node ships inside the bundle as a sidecar; inference comes from the engine, running locally or on your LAN.

One static Rust binary — a coding agent, the MCP server, and every product of the cloud from your terminal. No runtime, no daemon.
View sourceEngine
The inference engine that actually runs the model. LLM and embedding serving in Rust, built for local hardware first.
View sourceML
The compute core underneath: multi-backend tensors across CPU, CUDA, Metal, ROCm and Vulkan, with quantization built in.
View sourceEnso, our frontier model
Hanzo’s flagship AI — one model that orchestrates the world’s best models into a single API to tackle complex, multi-step work. Available on Hanzo Cloud.
FlashProUltraone OpenAI- and Anthropic-compatible APIEvery capability. One API.
Every capability is one route on api.hanzo.ai/v1. Open source, metered, and settled on-chain.
The reasoning is published
Measured campaigns, negative results and formal work behind the stack — written up, with the PDFs and the LaTeX in the open.
From frontier model to shipped product
Start with the model, build your app, and run it on the cloud — one continuous path.
Start with Enso
Build on Hanzo’s frontier model — one OpenAI-compatible API to the world’s best models, orchestrated per task. Flash, Pro, and Ultra presets.
