Decision model
Model Routing
Choose the tool, model and reasoning mode deliberately — not the most expensive option by default.
Reasoning mode names and availability vary by provider and change over time. The names below are a configurable decision model, not a claim about any specific vendor’s current offering.
Task categories
Route by the kind of task.
-
Strategy and product decisions
Direction, prioritization and scope. Favors strong reasoning and broad context over raw speed.
-
Implementation
Building and changing code or content within clear scope. A capable model at a justified reasoning level.
-
QA and verification
Checking that a change does what it should. Often a focused, scoped pass rather than the largest mode.
-
Research
Gathering and synthesizing information before deciding. Breadth matters more than maximum depth.
-
Critical multi-agent review
High-stakes changes verified by independent passes. The case where extra reasoning and redundancy are justified.
Reasoning modes
Escalate only when the task earns it.
- Normal Everyday tasks with clear scope and low risk.
- High Harder reasoning, ambiguity, or wider context.
- Extra Deeper analysis when correctness is sensitive.
- Max The hardest single-pass problems.
- Ultracode Multi-agent orchestration for the most demanding work.
Do not use the most expensive mode for every task. Use the smallest mode that can safely solve the problem.
