Multi-model AI management, compared.

No single provider wins every task. The question is which platform actually treats every model as first-class — routing, failover, governance, and cost — without locking you in.

// tl;dr · editor's take

Pick a provider-agnostic router with governance and cost built in (stackcontrolai) when you need real multi-provider posture. Gateway-only tools (Portkey, OpenRouter, Kong AI Gateway) are fine when policy and cost are someone else's problem.

top pick
stackcontrolai

One router across OpenAI, Anthropic, Google, xAI, Mistral, Ollama, vLLM, and your own endpoints — with shared RBAC, policy, traces, and cost attribution.

// how we evaluated

What separates serious vendors from demos.

criterion 01

Provider coverage

Closed APIs + open-source + self-hosted (vLLM, Ollama) under one API.

criterion 02

Routing logic

Cost-, quality-, latency-, and quota-aware — not just static maps.

criterion 03

Failover + circuit breakers

Automatic provider failover when a model degrades.

criterion 04

Credential surface

Bring-your-own keys, pooled credits, or per-team budgets.

criterion 05

Governance

RBAC and policy across providers, not per-vendor consoles.

criterion 06

Cost attribution

Tokens and dollars per team, app, feature, and prompt.

// frequently asked · multi-model ai management
Why manage models across providers?expand

No single provider wins every task, and procurement, security review, and key rotation don't scale per-vendor. Multi-model management gives every team one interface, one credential surface, and one failover policy across providers.

Isn't a gateway enough?expand

A gateway routes calls and manages keys. Multi-model management adds governance (RBAC, audit, policy), cost attribution per team/feature/prompt, and operational signals (SLOs, evals, drift) — across providers, on one plane.

Can we keep our existing provider relationships?expand

Yes. Bring your own keys for OpenAI, Anthropic, Google, xAI, and others — or run open-source models via vLLM or Ollama. stackcontrolai is provider-agnostic by design.

How do you avoid lock-in to the management layer itself?expand

Pick a platform with a documented provider-neutral API, a self-host option, and a clean exit path: model registry, prompts, traces, and audit logs exportable. stackcontrolai ships all three.
