The Brutus Router · catalog v2026-07-20.2
Routing with receipts.
Most model routers are black boxes. Ours shows its work: every decision is grounded in independent public evaluations — the Artificial Analysis Intelligence Index and LMArena's human-preference data — under a versioned, auditable catalog. And every routed request logs what it actually cost against the frontier-on-everything counterfactual. Measured, not marketed.
The catalog the router runs on
The production routing table, verbatim. Sourced scores carry their authority and as-of date; models the authorities haven't scored are marked unsourced and never dressed up as data.

Data policy: OpenAI and Anthropic models in this catalog are served under provider API terms that do not train on your inputs by default, with zero-data-retention available to qualifying enterprise agreements — and with an org inference key connected, your own DPA governs directly.
Open-weights entries are served under their host's own terms — verify data policy with the host before routing sensitive work.

What the router picks — and why
Selection rule: models within a complexity-based tolerance of the best task quality qualify; the cheapest qualifier wins. Simple, deterministic, and auditable — no learned black box.

The receipt
Every routed request in Brutus logs its actual cost — across every step of the execution strategy — against what the same request would have cost running a frontier model over the full input. The savings figure your team sees is computed from your own ledger, not a marketing benchmark. Beyond model choice, the router executes your organization's curated techniques (map-reduce over long material, draft→self-critique for high-stakes writing) and inherits Brutus's guardrails: approved-tool enforcement, data-sensitivity routing, and a full audit trail on routing credentials.
