# Routing recommendations

Derived mechanically from `capability-matrix.json` (2026-11-01T07:22:05.282Z). The in-app router uses the same data at runtime; the owner can override any choice.

## Modes

- **Quality** — highest quality score; ties broken by higher list price (assumption: the vendor's higher tier is stronger on tasks harder than this suite), then latency; *-pro models excluded (latency): `claude-fable-5-1` (100%, 1321 ms, $10 / $50), `gpt-6-astra` (100%, 2190 ms, $10 / $50), `claude-fable-5` (100%, 2691 ms, $10 / $50)
- **Fast** — lowest median latency among models scoring ≥ 89 %: `gpt-4.1` (89%, 704 ms, $2 / $8), `claude-haiku-5-5` (100%, 883 ms, $0.1 / $0.5), `gpt-5.4-mini` (89%, 888 ms, $0.75 / $4.5)
- **Economy** — cheapest blended price among models scoring 100 %: `gpt-5-nano` (100%, 3034 ms, $0.05 / $0.4), `claude-haiku-5-5` (100%, 883 ms, $0.1 / $0.5), `gpt-6-luna` (100%, 2005 ms, $0.1 / $0.5)
- **Automatic** — classify the task (code / math / vision / long document / general / French), pick the first candidate of the matching task list below that is available, fall back to the Quality list.
