# AdvisorTools brings multi-model escalation to any agent

> New AdvisorTools lets an agent run a fast, cheap model as its primary and consult heavier models only when it decides a problem needs one. Hand it a list of advisors and it can ask one by name or ask them all and compare.

Picking just one model for an agent means picking a compromise.

Go big and you pay frontier prices on every trivial step. Go small and you're exposed the moment a genuinely hard sub-problem shows up.

Our new `AdvisorTools` gives you a compromise-free path forward. It lets you run a fast, cheap model as the primary and it consults heavier models only when it decides it needs to.

To set up, you hand it a list of advisors. You can even add a note on what each one is good for. The agent then gets two tools. It can ask one advisor by name, or ask them all and compare what comes back.

```python
from agno.agent import Agent
from agno.models.anthropic import Claude
from agno.tools.advisor import AdvisorTools

agent = Agent(
    model=Claude(id="claude-haiku-4-5"),
    tools=[
        AdvisorTools(
            advisors=["google:gemini-3-pro", "openai:gpt-5.5"],
            descriptions={"gemini-3-pro": "Strong at long-context analysis"},
        )
    ],
)
```

The descriptions do real work. They tell the primary model which advisor to reach for, so a long-document question routes to the long-context specialist and everything else goes where you pointed it. The primary keeps control of the conversation and spends the expensive tokens only when a problem earns them.

Take a minute to think about what this changes about model choice, and how your work will change when you can stop betting the whole agent on one model.
