eu/jev is an API-first platform that provides a System One model hosted exclusively in Germany, designed for developers who need structured decision-making from text input. The API supports three decision types: choice (select among options), no/yes (binary answer), and score (numerical rating). It is built with European privacy standards in mind: all inference runs on a Hetzner server in Germany, prompts and answers are not stored, and a data processing agreement is readily available. Developers can integrate the API using a standard Jev-style request with their API key and base URL, setting the model to jeff-latest. The platform is ideal for applications like routing customer support tickets, sentiment analysis, and content moderation, returning structured JSON answers ready for automation.

Is eu/jev worth the price?

Good value

At €37 per billion input tokens with free output, this is dramatically cheaper than most proprietary APIs (which typically charge per token for both directions).

However, the single-model offering and lack of free trial or tier options mean it may lack flexibility for heavy experimentation. Best for EU-based teams that prioritize data sovereignty and need a low-cost, privacy-compliant decision-making API.

eu/jev FAQ

What types of decisions can the System One model handle?

The API supports three decision types: choice (select one option from a set), no/yes (binary answer), and score (numerical rating). You specify the decision type and criteria in the request, and the model returns a structured JSON answer.

How does the API ensure GDPR compliance?

All inference runs on a server in Germany, prompts and answers are not stored, and a data processing agreement (DPA) along with a subprocessor list is available upon request. No proxy or external model API sits between your request and the server.

Is there a free tier or trial available?

You can get started with €5 credit after creating an account. There is no permanent free tier, but the initial credit allows you to test the API before committing to paid usage.

What programming languages are supported for API integration?

The API uses standard HTTP requests with Bearer authentication. Example code snippets are provided for JavaScript, Python, and cURL, but any language that can make HTTP requests can integrate with the API.

Can I use this API for real-time content moderation?

Yes, the API is designed for tasks like content moderation. You can send text and ask the model to classify it (e.g., safe vs. unsafe) using the choice or no/yes decision types, and receive a structured answer quickly.

How does pricing work for input tokens?

Pricing is €37 per billion input tokens. Output tokens are free. You pay only for the text you send to the API for inference. The initial €5 credit allows you to test the service.

What is the difference between choice, no/yes, and score endpoints?

All three are handled by the same endpoint. You specify the type in the request: 'choice' returns a selected option from your provided criteria, 'no/yes' returns a boolean answer, and 'score' returns a numerical rating. The model interprets your instructions and criteria to produce the appropriate output.

Where is the inference server physically located?

The inference server is hosted by Hetzner in Germany. Your request goes directly to that server without passing through any proxy, CDN, or external model API.
