Open-source AI infrastructure. The parts below run on your own machine with no
account; the hosted cloud at api.hanzo.ai adds sign-in, billing and hosted models.

Zen generates. Enso routes. Kai decides.
| Model | What it is |
|---|---|
| Zen | open-weight model family: language, code, vision, audio, embeddings (weights) |
| Enso | routes every call, in every modality, to the model that should take it; one API |
| Kai | decision model: turns heterogeneous evidence into calibrated, typed, consistent decisions |
We build and run these for companies: hanzo.ai/enterprise · hanzo.ai/contact
| Repository | What it is | Start it |
|---|---|---|
| base | SQLite application backend, one Go binary | in a clone: go run ./examples/base serve, then http://127.0.0.1:8090/v1/ |
| cloud | the open-source cloud, one Go binary with the console built in | in a clone: make build && CLOUD_DEV_UNENCRYPTED=1 CLOUD_LISTEN=127.0.0.1:8080 CLOUD_DATA_DIR=.dev/data ./cloud, then http://127.0.0.1:8080 |
| zip | Go framework: an operation declared once is served as REST, OpenAPI and an MCP tool | in a clone: go run ./examples/hello, then http://localhost:8080/hello |
| mcp | MCP server for coding agents | npx -y --package=@hanzo/mcp hanzo-mcp serve (stdio) |
| engine | model inference, in Rust | cargo install --git https://github.com/hanzoai/engine --locked hanzo-cli, then hanzo-engine serve -m <model-id>, on http://localhost:1234/v1 |
The cloud command runs unencrypted, for local development only: its make dev
cannot encrypt a store yet.
