Q: Choose the engine and model for a task

Tycoon can run a task on any engine and any model — the choice is yours, and it now sits right on the New task panel instead of behind a collapsed menu.

Q: Where do I see it?

Open New task, write your request, and pick who should do it. As soon as you choose a runner that can run on more than one engine — a developer agent, a custom agent, or one you hired — two controls appear in the composer: an Engine pill and a Model pill. They are always visible; there is nothing to

Where do I see it?

Open New task, write your request, and pick who should do it. As soon as you choose a runner that can run on more than one engine — a developer agent, a custom agent, or one you hired — two controls appear in the composer: an Engine pill and a Model pill. They are always visible; there is nothing to expand.

What can I pick?

Engine — nine runtimes: the built-in Claude Code, Codex, and Hermes, plus six Bring your own CLIs you have paired. Leaving it on Auto / Default lets Tycoon Agent pick the best one.
Model — the full catalog, selectable across engines. Choosing a model that needs a different engine switches the engine for you; otherwise the Model follows the engine's default until you change it.

Tycoon Agent (the manager) runs on a fixed internal engine, so these controls stay hidden until you assign the task to another agent.

What does it cost?

Usage is billed to your workspace wallet at actual metered cost. Heavier models cost more per token, so Auto is usually the economical default — switch up only when a task truly needs it.
