OpenKai is Kaidera's terminal-first coding agent. Its TUI lets you choose models, supervise worker agents, use an advisor for a second opinion, ask an explicit Fusion team to compare hard choices, and optionally share durable project memory through Cortex.
openkaiThen use these three commands:
/login connect a provider
/model choose the active model
/settings change durable preferences
Ask a small question about the current folder first. Type /help at any time.
| Need | Control |
|---|---|
| Continue the previous conversation | . |
| Search conversation history | Ctrl+R |
| Leave safely and keep an unfinished draft | Ctrl+D |
| Watch or steer a worker agent | Alt+A, select an agent, then Enter |
| Ask a deliberate model team | /fusion your task |
| Check Cortex and memory health | /cortex status, /memory stats |
Two-model teamwork is the normal mode. The active model works while an advisor model checks progress and sends notes. Turn it off in Settings → Model → Two-model teamwork when you deliberately want one model. A child agent can also be set to one-model mode in Agent Hub.
Fusion is a focused comparison for a difficult decision. /fusion starts an Architect, a Builder, and a fresh Judge. The Architect plans, the Builder gives an independent answer, and the Judge tells you what agrees, which choice to keep, what to set aside, and what to check.
/fusion design a safe migration for this service
/fusion help
Cortex is a shared project notebook. Enable it from Settings → Memory, then:
/cortex status
/cortex install
/cortex register [project] [agent] [role]
Installation and registration ask before changing anything. Registration requires CORTEX_ADMIN_TOKEN; a normal API token cannot create a shared project or roster.

0.1.15 is the current release (2026-09-17): npm @kaidera/openkai and @kaidera/openkai-engine (latest), the GitHub release with signed binaries for macOS, Linux and Windows plus SHA256SUMS.txt, the Homebrew tap (kaidera-ai/tap/openkai), the bun add -g @kaidera/openkai channel, and scripts/install.sh (default v0.1.15). All four distribution channels were independently re-verified end-to-end on 2026-09-17 after a Homebrew-tap deploy-key incident (see Program/OpenKai/PROGRESS.md in the private Kaidera-AI/kaideraos repository — not linkable from here). Releases ship only on explicit CTO consent per RELEASE_SOP.
Where the code is. This repository holds the product documentation, the programme ledgers under Program/, and the release machinery. The runtime source is maintained under products/openkai in the private Kaidera-AI/kaideraos repository and materialised into each release by release.yml as a SHA-256-verified product-subtree archive with provenance. There is no buildable code tree on this branch by design.
Windows validation caveat: the Windows binary has not received a PowerShell parser check or a Windows-host install run. Use it knowing that; macOS and Linux are the validated hosts.
