Agents without an API

The complete intelligence runtime you can ship inside your app.

Write your app in TypeScript. Have it compose local models, spawn agents that share attention state, and use turnkey abilities to perform real-world tasks. Ship it like a regular desktop app that works offline or a web app that serves multiple users.

01 / ABILITIES

Extend. Interact. Recurse.

Agents use Abilities to act on the world and on live inference simultaneously.

Abilities are inference-native. They run inside the model’s execution rather than behind a network boundary, so an extension can see who called it, what that caller already knows, and what else is running — and can fork that state into new agents.

Lloyal hosts a signed channel of 1st & 3rd party Abilities. Installing one brings it all into your app in a single command, for your in-app agents to consume: tools and their schemas, a live source, situation-aware skills[1], and the models it composes. DeepSeek’s Harness bets on a plugin ecosystem for its own agent. Abilities are that ecosystem for the apps you ship.

How Abilities work →Browse Abilities →
Level 0

Tool calling

Its arguments. The function cannot know who called it, what else is running, or what happens next.

Level 1

MCP

Its arguments, in its own process. Language freedom and isolation — the right default for most integrations.

Level 2

Skills

Its arguments, and the context window. The extension carries procedure now, not only operations.

Level 3

Abilities

The execution itself. The calling agent, its live inference state, its lineage, its siblings — the authority to fork it into new agents, and to require the harness to load another model before it will run.

02 / THE HARNESS

The Model in MVC now thinks.

For two decades the Model in MVC was inert—rows in a database, waiting to be queried. Put a live language model in that slot and every other part holds: product surfaces are still the Views, and the harness is the Controller, ordinary TypeScript deciding how the application's intelligence collaborates, acts, recovers and continues. What changes is that this Model thinks, and it keeps thinking while your code governs it—the same code whether it runs a 4B model on a laptop or GLM-5.2 across a cluster of B200s.

The model supplies the intelligence. The harness supplies the institution.

Program the behaviour once — regardless of product surface or compute:
