The Core Agent is general-purpose and is the main way to work on AI Suite. An Assistant is an optional custom agent tuned for one recurring job. You give it a name, instructions, a model, and — if you like — tools and documents. Then you pick it in the Agents tab.If you’ve read Build an app, this will feel familiar. An Assistant is like an app that can also use tools and take action.
Go to Agents (or the Platform area) and choose Create → Assistant.
Starting a new Assistant.
2
Name it
Give it a clear name, like “Travel Planner” or “Support Helper”.
3
Write its instructions
Tell it who it is and how to behave, in plain words:
You are a friendly travel planner. Ask the user for their destination, dates, and budget. Then suggest a simple day-by-day plan. Keep it short and cheerful.
Good instructions = clear job + clear tone + any rules. Imagine training a new assistant on day one.
Writing the Assistant's name and instructions.
4
Choose a model
Pick the AI brain — see Choosing a model. Default is fine to start.
5
Add tools (optional)
Turn on any tools it should use (like a connected calendar or search). See Connect your tools.
Most people should stay with the Core Agent for everyday work (docs, sheets, PDFs, multi-step tasks). Build an Assistant only when you want a named specialist with fixed instructions you reuse often.Managed agents are an advanced option — skip them unless you specifically need more autonomous automation.
