How to pre-configure Agent Zero with A0_SET_

Working with VPS or just in need of auto-config? You can skip the Settings UI entirely and set any Agent Zero setting straight from your .env file. This is especially useful for Docker deployments, CI pipelines, or if you just want a reproducible setup.

How it works

Add any setting to your `.env` file with the `A0_SET_` prefix:

```

A0_SET_{setting_name}={value}

```

A few examples:

# Models

A0_SET_chat_model_provider=anthropic

A0_SET_chat_model_name=claude-sonnet-4.6

A0_SET_chat_model_ctx_length=200000

A0_SET_util_model_provider=openrouter

A0_SET_util_model_name=google/gemini-3-flash-preview

# Agent profile

A0_SET_agent_profile=agent0

A0_SET_agent_knowledge_subdir=custom

The name is case-insensitive (A0_SET_chat_model_provider and A0_SET_CHAT_MODEL_PROVIDER both work).

These env vars act as defaults: if you later change a setting in the UI and save, the saved value takes priority. Think of A0_SET_ as default if nothing else is configured.
