OpenRouter.dev
🧱 TL;DR
OpenRouter.dev is an platform designed to simplify and unify access to multiple AI model APIs, offering developers a streamlined way to integrate, route, and manage requests across diverse LLM providers. You must purchase credits to use the product so the author of this wiki couldn't do a deep dive:

Bring Your Azure Key
Here is the JSON you (manually) construct to bind openrouter.ai into Azure.
{
"model_slug": "the-openrouter-model-slug",
"endpoint_url": "https://resource.services.ai.azure.com/deployments//chat/completions?api-version=",
"api_key": "your-azure-api-key",
"model_id": "the-azure-model-id"
}
Not all models are supported and I noticed some like "3.5-turbo" are in openrouter but no longer available to create (fully deprecated) in Azure itself. I created two models GPT-4-1 and GPT-4.
"The cost of using custom provider keys on OpenRouter is 5% of what the same model/provider would cost normally on OpenRouter and will be deducted from your OpenRouter credits" (https://openrouter.ai/docs/use-cases/byok).
I bolded the concerning part; this means you still spend credits even when using your own key.
I went ahead and tried it anyway and see these errors for both models
💡 Why It Matters
OpenRouter.dev addresses the fragmentation in the AI ecosystem by providing a single API endpoint for multiple LLM providers. This reduces integration complexity, increases flexibility in model selection, and enables dynamic routing based on intent, cost, or performance. Organizations can avoid vendor lock-in and optimize their AI workflows for cost, compliance, and quality.
