# Cohesivity vs OpenRouter

OpenRouter: “The Unified Interface For LLMs.”

Your agent needs to call a few models. OpenRouter is the obvious pick: hundreds of them, dozens of providers, one OpenAI-compatible endpoint, with routing and failover across the lot. On breadth of models, it is hard to beat.

Here is where Cohesivity is different, and where it is honestly weaker. It is not a model router. Its AI gateway gives an app multi-provider access across OpenAI, Anthropic, Google and xAI, as one line in a backend that also has a database, storage, auth and hosting, all provisioned by the agent with no signup. So the fair read is blunt. OpenRouter wins on how many models you can reach. Cohesivity wins when you want that gateway to arrive inside a backend, with nobody creating an account or an API key first.

| what it is        | A whole backend (database, storage, auth, hosting, AI) with a built-in gateway.                | A dedicated LLM router: one API across many models and providers.      |
| model breadth     | Chat, embeddings and images across OpenAI, Anthropic, Google and xAI.                          | Hundreds of models across dozens of providers. Far more model choice.  |
| signup            | None. The agent provisions it, and keys stay server-side.                                      | An account and an API key are required, including for the free models. |
| beyond the models | The same API also provisions a database, storage, a vector store, auth, hosting and a browser. | Focused on model access, routing and provider failover.                |
| billing           | Plus $20, Pro $100, one shared balance. Upstream keys stay server-side.                        | Pay per usage. Bring-your-own-key routing is supported too.            |

where Cohesivity fits

- Model access with no separate signup or key. The agent provisions the gateway with the rest of the backend, so there is no OpenRouter-style account or API key to make first.
- One backend instead of a rack of vendors. A model router, plus a database, plus auth, plus a host becomes one API, with the provider keys managed for you.
- Keys never leave the server. Upstream credentials are injected server-side, so the app calls the gateway and never touches a raw model-provider key.

when OpenRouter is the better call

Pick OpenRouter if model choice is the point. Nothing here bundles models the way it does. If you want to route across many providers, compare prices, or fail over between models automatically, that is its whole reason to exist.

Pick OpenRouter if you already have a backend and only need the model layer. It is a clean, OpenAI-compatible drop-in for exactly that, and you do not want the rest of a backend coming from a router.

This is a different-tool comparison more than a head-to-head. OpenRouter is the specialist at reaching many models. Cohesivity's gateway is a convenience inside a backend. If the router is your whole requirement, OpenRouter is the deeper tool for it.

questions

### Is Cohesivity an OpenRouter alternative?

Only for the case where you would rather your AI gateway came inside a no-signup backend than as a standalone router. Cohesivity offers multi-provider access across OpenAI, Anthropic, Google and xAI as part of a backend the agent provisions. OpenRouter is a dedicated router with far more models. If model breadth is the requirement, it is the better fit.

### How many models does Cohesivity's gateway support versus OpenRouter?

Cohesivity's gateway covers OpenAI, Anthropic, Google and xAI. OpenRouter offers hundreds of models across dozens of providers, which is much more breadth. Cohesivity's edge is not model count. It is that the gateway ships with the backend and needs no signup.

### Do I need an API key like OpenRouter requires?

Not as a developer. Cohesivity injects the upstream provider keys server-side, and the agent provisions access with no account. OpenRouter requires an account and an API key, even for its free models.

### Can my agent set up model access automatically?

Yes. The agent provisions the gateway with an HTTP call as part of building, with no dashboard or key-paste step.
