2026-05-19 Cost Model For Agent Workers

The future of Prox OS development may involve many AI workers. That does not mean every task should use the most expensive model.

Cost control is part of architecture.

Practical Routing

• Use subscription tools for exploration and interactive thinking.
• Use API-based automation when repeatability and visible cost matter.
• Use strong reasoning models for architecture and integration.
• Use strong coding agents for small, high-risk implementation slices.
• Use cheaper models for docs cleanup, first-pass compression, and low-risk repetitive work.
• Use local or open models only for tasks where privacy, quality, and risk are acceptable.

The Real Asset

The real asset is not a single model or editor. It is the control plane:

• Task graphs.
• Agent scopes.
• Context packs.
• Prompt templates.
• Quality gates.
• Integration reports.
• Release plans.

Better context makes cheaper models safer. Hard scope makes strong models more effective. Smaller tasks reduce retry cost.

The goal is not to avoid paying for useful tools. The goal is to spend reasoning where it changes outcomes.
