what AI can build
API key gateway that fans out to 2–3 model providers with usage logs.
A proxy that routes to OpenAI/Anthropic is buildable; OpenRouter’s model catalog and billing UX are the convenience.

questions
Can AI replace OpenRouter?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: huge model catalog, ranking. Validate the prompt against your own acceptance criteria before committing.
How much does OpenRouter cost?
OpenRouter's pricing is usage-based or varies by plan. Use the linked pricing source for the current amount; the catalog last checked it on 2026-08-05.
What do I lose by replacing OpenRouter?
Honestly: huge model catalog; ranking; credits UX. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to OpenRouter?
No mature open-source alternative is listed yet. The prompt is an unverified starting point, not proof that a one-shot replacement will work.
