Tier 1/2/3 Orchestration
Tier 1/2/3 orchestration is Theo’s adaptive routing — Tier 1 handles single-shot replies, Tier 2 hands off to a tuned specialist, Tier 3 fans out to a planner-specialist-evaluator multi-agent DAG.
In depth
Tier 1 is the fast path: a direct generateText call against the active mode’s primary engine. Tier 2 dispatches to a specialist agent (e.g. coder, researcher, designer) using a curated tool set and a focused prompt. Tier 3 launches a planner that decomposes the task into sub-agents executed in parallel, then an evaluator that synthesizes the final answer.
Routing is decided by the planner gate, which uses message complexity, requested artifacts, and intent confidence to pick the cheapest tier that will produce a satisfying answer.
Examples
- “What time is it in Tokyo?” = Tier 1
- “Build a launch plan” = Tier 3
