ModelPilot vs. OpenRouter

OpenRouter is a great unified gateway — one API to hundreds of models. It solves a different problem from ModelPilot, and (with Fusion) optimizes in the opposite direction.

In one line: OpenRouter routes your traffic through its servers to reach many providers, billed on usage. ModelPilot is a cost layer on your own Claude key that routes each request down to the cheapest good-enough model — your prompts never touch our servers, and you pay only a slice of what we save.

The differences that matter

Data path. Every OpenRouter request crosses your client → OpenRouter → provider; OpenRouter sees the prompt to route and meter it (a subset is sampled for categorization). ModelPilot classifies locally — only a task category + numeric features ever reach us; prompt text, outputs, and your API key never leave your system.
Direction. OpenRouter Fusion turns a prompt into a multi-model panel + judge for higher quality — priced at roughly 4–5× a single completion. ModelPilot does the reverse: route down to one cheaper model that's provably good enough, to cut the bill.
Billing. OpenRouter passes through provider pricing with a credit fee; BYOK is free to ~1M requests/mo, then a 5% fee. ModelPilot charges a % of realized savings — no savings, no bill.
Relationship. With OpenRouter, it becomes your API + billing layer. With ModelPilot you keep your direct Anthropic account, and we fail open straight to Anthropic if we're ever down.
Proof. We measure savings against a held-out control arm and check the cheaper model side-by-side for non-inferiority on your traffic — an audited number, not a quoted range.

	OpenRouter (incl. Fusion)	ModelPilot
Type	Hosted multi-provider gateway	Drop-in proxy on your Claude account
Prompts	Flow through OpenRouter	Never leave your system
Goal	Access; Fusion = higher quality (≈4–5× cost)	Lower cost, provably good enough
Billing	Usage + fee / 5% BYOK	% of realized savings
Scope	Many providers	Deep on Claude

When OpenRouter is the better fit

If you want one API across many providers, cross-vendor fallbacks, or Fusion's ensemble for maximum answer quality, OpenRouter is the right tool — we're not trying to replace it. Some teams run both: OpenRouter for breadth, ModelPilot to stop overspending on the easy requests.
