Turn any OpenAI-compatible OpenCode Zen model into a Home Assistant conversation agent. Talk to your home, control devices, and use the free models — all with one API key.
OpenCode Zen is a curated AI gateway that only serves tested, verified models. This integration brings that quality to Home Assistant.
Add unlimited agents — one per model — and switch between them from Assist, dashboards, or automations.
Let the model call tools to interact with your devices and entities, just like the official OpenAI and Anthropic integrations.
Works out of the box with the Assist voice pipeline and voice assistants.
Use the free OpenCode Zen models (like deepseek-v4-flash-free) at no cost.
Send images and PDFs along with your messages for richer responses.
Generate structured data on demand with AI tasks, and attach files to guide the results.
Real-time token streaming in the conversation UI for a snappy feel.
Sign in at opencode.ai/auth, add billing, and copy your API key.
Install via HACS or manually — full instructions on the install page.
Enter your key, pick a model, and start chatting. See the configuration page for details.
