How this was valued: Continuous saturation of the documented per-API-key 60-second window (10 requests, 4M input tokens, 100k output tokens) with each request's total tokens capped by the served models' documented 262,144-token context, priced for the costlier served model, Qwen3.8-27B, at the cheapest current OpenRouter listing for the exact model because neither Hetzner (free while experimental) nor Alibaba Cloud Model Studio's international catalog publishes a paid rate for these exact models. The context-derived per-request ceiling (10 x 262,144 = 2,621,440 tokens/minute) is tighter than the 4M input-TPM limit and was used. Assumes uninterrupted saturation of one API key with no latency, concurrency, availability, or fair-use loss; the value is a paid-equivalent ceiling, not expected usage.

What happens to your prompts?
Hetzner documents no ordinary prompt/output retention, no content training right, and EU-hosted processing.
- Plan Scope
- Hetzner Experiments Inference API, a best-effort experimental service for existing Hetzner customers.
- Prompt Retention
- Hetzner states it does not retain prompt or response content after processing unless legally compelled.
- Response Retention
- Same non-retention statement as prompts.
- Ordinary Logging
- Usage metadata is retained for operation and enforcement without prompt or response content.
- Model Training
- No retained inference content is available for ordinary model training, and no training right is disclosed for the experimental API.
- Product Improvement
- Service telemetry may support operation of the experiment; the product documentation does not authorize content-based improvement.
- Human Or Operator Access
- Transient access necessary to process a request is possible; retained content access is limited to a legal-compulsion exception.
- Subprocessors And Routing
- Hetzner provides the hosted inference infrastructure in the EU under its terms and DPA; model licenses can separately restrict use of outputs.
- Deletion Controls
- Prompt and response content is not ordinarily retained. Account and personal-data rights are available through Hetzner's privacy and DPA procedures.
- Caveat
- This is a non-production experiment without an availability commitment. The legal-compulsion exception and retained usage metadata mean it is not a universal zero-data promise.
