European by design

EU providers, automatic failover. Your data never leaves Europe.

Built on values.

The price is the only thing this offer changes. Everything below stays true on every request.

  • Sovereign

    Your data stays under European jurisdiction. No foreign government access, no loopholes.

  • Private

    Encrypted in transit and at rest, with a layer on top. We never train on it, and never sell it.

  • Transparent

    See where your data goes, which model ran, and what each call costs and emits.

  • Sustainable

    EU providers on low-carbon energy. The rest, we offset. Effectively CO₂-neutral.

FAQ

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
