Tool calls

The right function, with the right arguments.

Turn a request into the exact function call your system expects: the right tool, valid arguments, your field names and conventions. It is the part of an agent that actually does things, trained to do it the way your systems need.

What it does

Built for tasks like these.

How it works

From your examples to a model you own.

  1. 01

    Collect calls that worked

    Requests paired with the call your team or system made in response. The contact model learned from 801.

  2. 02

    Train on your tools

    The model learns your function names, argument formats and when to make no call at all.

  3. 03

    Call your systems

    Validate each call against your schema and run it, all inside your network.

Private by default

Your requests never leave the building.

Tool calls carry the data they act on: customer names, amounts, account details. A local model reads the request and writes the call without any of it leaving your network.

  • The model changes whenever they ship
  • You pay for a huge general model to do one narrow task

  • The model is a file you own; it changes when you retrain it
  • Small enough to run on hardware you already have

Trained, not prompted

Accurate on your task.

Our contact-notes model writes update_contact calls from meeting notes and gets 137 of 142 held-out notes exactly right. The best frontier model got 77; most of its misses were conventions, not comprehension.

And it costs less

No per-call bill.

Agents make many calls per task. When each step is a local model, the loop costs nothing per step.
