Plenty of tools can fan out to multiple models. Very few treat cost governance and data trust as first-class alongside routing. Here's the honest landscape against the tools teams actually evaluate.

RouteLLM (LMSYS) is an open-source strong/weak routing model; OpenRouter is a hosted multi-model aggregator; LiteLLM is an open-source multi-provider proxy with budgets & caching; Portkey is a commercial AI gateway with guardrails. All are capable tools — this reflects out-of-the-box capability as commonly deployed and will vary by version and configuration. Corrections welcome.
