Enterprise Trust

AI Foundation Services gives you a single OpenAI-compatible API across two clearly separated categories of models — those operated by Telekom in the EU/EEA, and those forwarded to third-party providers under their own terms. This page summarizes the trust and compliance posture; the Service Description (PDF) (v1.20) is the binding source.

No training on customer data

Regardless of which model you select hosted by Telekom, customer prompts and responses are never saved or used to train or fine-tune any model.

Two Model Categories — Pick the Right One for Your Data

The Service Description splits the catalog into two categories with materially different data-sovereignty profiles. Selecting a model is selecting its data-handling regime.

Category 1 — EU/EEA & adequacy-decision processing

Operated by Telekom on T-Cloud Public. Examples:

• Meta Llama 3.3 70B Instruct
• Mistral Small 3
• Alibaba Qwen3 (VL, Coder, Next variants)
• OpenAI GPT-OSS-120B
• DeutschlandGPT Llama-BildungsLLM
• OpenAI Whisper Large v3 / v3 Turbo (STT)
• Jina embeddings v2, BAAI BGE m3 (embeddings)

For these models:

• Data processing happens inside the EU/EEA or in countries with an EU adequacy decision
• Customer prompts and returned results are not stored and not viewable by Telekom or third parties

Category 2 — Third-party providers, sub-processors worldwide

Forwarded by Telekom directly to the third-party provider, who runs the model on its own infrastructure. Examples:

• OpenAI GPT-4o, GPT-4.1 family, GPT-Image-1, o1/o3/o4 family, GPT-5 family, Ada-Text — on Microsoft Azure (France/Sweden)
• Anthropic Claude (3.7, 4, 4.5, 4.6 Sonnet/Haiku/Opus) — on Google Cloud or Microsoft Azure
• Google Gemini 2.5 / 3 family — on Google Cloud
• Mistral Medium 3 — on Google Cloud

For these models:

• The third-party provider may operate sub-processors worldwide, so customer data may be processed worldwide
• By selecting a Category 2 model, the customer accepts the third-party provider’s terms, license, and data-protection policies
• Outages of these third-party providers are excused from Telekom’s availability calculation

Caution

Certain data categories (for example social or health data under German law) may not legally be processed outside the EU/EEA. Reviewing the legal basis for using a specific model is the customer’s sole responsibility.

EU AI Act Alignment

• Telekom delivers the service in line with its applicable obligations under Regulation (EU) 2024/1689 (the AI Act).
• The customer is contractually required to use the service in compliance with the AI Act.
• The service is not designed or permitted for high-risk AI systems as defined by the AI Act, nor for any prohibited use case.
• The service is not a medical device under MDR and may not be used for diagnosis, prevention, monitoring, prediction, prognosis, treatment, or alleviation of disease.

GDPR & Data Processing

• AI Foundation Services is delivered in compliance with EU Regulation 2016/679 (GDPR).
• A Data Processing Agreement (DPA) based on Telekom’s template is available on request — required if the customer processes personal data through the service.
• Telekom acts as a data processor; the customer remains the data controller.
• The customer is responsible for confirming that the data they submit is lawful to process, including processing-location restrictions.
