STACKIT AI Model Serving is the managed generative-AI service of STACKIT, the sovereign cloud brand of Schwarz Digits, the Schwarz Group's IT division, operated by Schwarz Digits Cloud GmbH & Co. KG from Neckarsulm, Germany. It gives applications API access to open-source large language models such as Llama, on infrastructure where the vendor says queries are neither stored nor used to train models. Hosting is in European data centres, presented as a GDPR-compliant alternative to US providers, with GPU and CPU compute on the same platform for training. Billing is token-based, with rates published per model tier. The limitation is breadth: an independent industry radar that recommends the service for German sovereignty needs notes that model selection stays limited compared with the hyperscalers.

## Key features

- API access to open-source large language models such as Llama, with model switching in the STACKIT Cloud Portal
- Data and queries neither stored nor used to train models, according to the vendor
- Hosting in STACKIT's European data centres, sold on data sovereignty and GDPR compliance
- Token-based billing with published rates for input, output and embedding model tiers
- GPU and CPU compute on the same platform for training and inference workloads
- RAG template and Terraform provider for integrating models into existing environments

## Use cases

- Running generative-AI features on models hosted inside the EU for data-sovereignty requirements
- Prototyping and operating LLM applications through one API without managing inference servers
- Training or fine-tuning models on STACKIT GPU compute next to the serving endpoint

## Pricing

Token-based: the product page publishes rates per million tokens by model tier, for example €0.15 for standard input, €0.45 for plus input, €1.50 for premium input, €0.25 for standard output and €1.75 for premium output, plus embedding rates from €0.02, all in the Germany South (EU01) region. No free allowance is advertised on the page read, and this record sets no comparable paid_from figure.

## FAQ

**What is STACKIT AI Model Serving?**

A managed service that serves open-source large language models through an API from STACKIT's European cloud, so applications can use generative AI without running their own inference infrastructure.

**Who operates it and where is it based?**

STACKIT is the cloud brand of Schwarz Digits, the Schwarz Group's IT and digital division; the vendor page names the entity Schwarz Digits Cloud GmbH & Co. KG and says the team is based in Neckarsulm, Swabia, Germany.

**How is it billed?**

By tokens, with published rates per model tier: for example €0.15 per million standard input tokens and €0.25 per million standard output tokens, in the Germany South (EU01) region. The page read advertises no free tier.

**Where is data processed?**

STACKIT hosts in its own European data centres, which the vendor presents as GDPR-compliant and sovereign, and states that user data and queries are neither stored nor used to train models.

**What does this record not establish?**

No vendor page read states a launch date for the service, its licence terms, or its own interface languages; the 2025 launch year comes from an independent industry radar, and a docs.stackit.cloud page tried for this record returned 404, so no docs_url is recorded.
