When the response ends, your prompt is gone.

Zero data retention

We hold prompts and completions in memory only. We never write them to disk. We keep the token count for billing. We keep nothing else.

Made in Germany

The API runs on servers in Germany. We process your requests there and nowhere else. No third country gets access to them.

DSGVO

We act as your processor under the DSGVO. You stay the controller. You can sign the data processing agreement before your first request.

You change two lines.

1
Create your API key.
One form. No sales call.
2
Set the base URL.
https://api.modelsheep.com
3
Send the first request.
Your prompts stay in Germany.
