Run Leading Open-Source Models Today

One API.
Multiple AI Models.

Your business is unique. Your AI models should be too. Whether customer service and marketing, creation and edutainment, coding, science and R&D - each AI workflow has different requirements and priorities.

Our European AI API connects you to curated leading open-source AI models for every business domain. Benchmarked and optimized for production-grade latency, predictable cost, and reliability. Safely hosted in the European Union.

Switch models anytime, compare performance, or adapt your stack as your needs evolve. No vendor lock-in, proprietary constraints or hidden dependencies — your workloads run efficiently across leading AI models with the best price-performance ratio in Europe.

Infrastructure is hosted in European data centers. ISO 27001, TÜVIT TSI, DIN EN 50600 and other certifications apply to the respective data center operators.

Frequently Asked Questions

The most important information at a glance. Contact us if you have any questions.

What is AKI.IO's European AI API?
AKI.IO provides easy, token-based access to leading open-source and open-weight AI models developed by providers around the world. All models are hosted on sovereign servers in Europe in compliance with GDPR requirements.
Who can use the service?
AKI.IO is a business-to-business (B2B) platform. The service is intended for companies, public institutions, and self-employed professionals acting on behalf of their business or professional activity.
How do I test the API?
It's simple: all models are available in a dedicated playground. In addition, anyone can create a user account and test the documented API with all its functions during a free trial period. Use in production then requires a business account.
How does the free trial work?
Simply create a user account. You will automatically receive a free trial period with tokens worth €10. The trial ends automatically; no credit card is required.
Which AI models are available?
Our range of curated and benchmarked open-source and open-weight AI models is constantly growing. We believe in highly specialized models for specific applications and constantly evaluate the latest top models.
How does the API work?
The interface follows industry standards such as the OpenAI API specification, relies on web protocols, and is available, or currently being developed, for all major frameworks.
Which infrastructure does the service run on?
We rely on HPC GPU servers that are tailored to the respective AI model. The entire infrastructure is hosted in European data centers. We use specialized local hosting providers. No hyperscalers or other non-European cloud services are involved.
Is AKI.IO GDPR-compliant?
Yes, AKI.IO is operated under strict GDPR requirements. The product stack is primarily built on open-source technologies and free of non-EU providers. Input and output data are not stored or used for training purposes. All data transfers are encrypted.
Where is the data processed?
All data is processed exclusively by inference AI models hosted on GPU servers in the EU, without external connections. No hyperscalers or other cloud services are used, and no data leaves our servers.
How do I use AKI.IO for projects in production?
Simply create a company account from your user account and accept our legal framework and the current price list. Generate as many API keys as you want for your projects — all of them will be billed centrally to your company.
How much does AKI.IO cost and how is it billed?
AKI.IO uses token-based billing exclusively. Costs are directly related to the number of tokens used and can be viewed at any time. Pricing is predictable and transparent, with no hidden fees.
What is your stance on open source?
Our product stack is primarily built on open-source technologies. We are committed to open standards, transparent development, and collaborative ecosystems. We support the community with our time, expertise, and capital in order to strengthen security, accessibility, and long-term sustainability.
