What is Melious?<br>A European platform that gives you one API for the latest open-weight AI models and tools for your AI applications, all running on a network of European infrastructure providers. You get one endpoint, one bill, one set of values — sovereignty, privacy, transparency, sustainability — across the whole stack.
Do I have to rewrite my code to switch?<br>No. If you're using the OpenAI or Anthropic SDK, point the base URL at api.melious.ai, drop in your Melious API key, and you're done. Same interface, European infrastructure underneath.
Do you train on my data?<br>No. Never. Your requests are end-to-end encrypted, stay on European infrastructure, and don't touch any training run — ours or anyone else's. We run inference, not a data collection scheme.
What does "sovereign" actually mean here?<br>Your data stays under European jurisdiction. Our infrastructure partners are based across the EU or European Economic Area. No US legal exposure, no foreign government access, no fine print that quietly says otherwise.
Which models can I use?<br>You can use the latest open-weight models across many different categories such as text generation, image generation, audio transcription, embeddings or reranking. Browse the full list in the Hub and switch seamlessly between models by changing one string.
What happens if a provider goes down?<br>Requests are routed across multiple European providers with automatic failover. If one goes offline, your traffic moves to another for high availability without you having to do anything.
