How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

About

Generated from the reference model catalogue (the OpenRouter listing) - regenerated daily as the line-up and prices change. Import it with registry://<slug>@<version> or osr stack apply; every target answers on https://openrouter.ai/api/v1 with your own key.

Google only: Lyria 3 Pro Preview for everyday requests, Nano Banana 2 (Gemini 3.1 Flash Image Preview) for moderate work, Nano Banana Pro (Gemini 3 Pro Image) for hard ones - with complexity rules and a cost-aware objective.

Targets

Lyria 3 Pro Preview (Google) - $0.00 in / $0.00 out per 1M tokens
Nano Banana 2 (Gemini 3.1 Flash Image Preview) (Google) - $0.50 in / $3.00 out per 1M tokens
Nano Banana Pro (Gemini 3 Pro Image) (Google) - $2.00 in / $12.00 out per 1M tokens

2 routing rule(s); every target answers on https://openrouter.ai/api/v1 (OpenAI-compatible).

Use it

Copy one of these into your project. Installing also returns the manifest and these snippets.

bash

osr stack plan registry://stack-google@1.0.0 --registry https://osr-api.kindrock-caaab1a2.centralindia.azurecontainerapps.io
osr stack apply registry://stack-google@1.0.0 --registry https://osr-api.kindrock-caaab1a2.centralindia.azurecontainerapps.io

Installed into a catalogue, chosen by a router

Install Google tiers and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.

For the business

What it costs to adopt - in engineering time.

Same client, same code
One base URL
The OpenAI-compatible endpoint answers your existing SDK calls; model=auto lets the router choose.
The SDKs
One URL, every vendor
No vendor lock-in
Point your OpenAI-compatible client at one address; add, swap or retire providers in the catalogue without touching application code.
Every vendor side by side
Next eligible model answers
Failover built in
When a provider is down or over quota the request moves on; the trace says it did.
