## What is SIMOSphere AI?

SIMOSphere AI is an OpenAI-compatible large-language-model inference API,
operated by SIMO GmbH (Aschaffenburg, Germany). It runs on EU-located
NVIDIA RTX 6000 GPUs and exposes open-weight models (Qwen3, Apertus,
Gemma, Llama) through a drop-in `Authorization: Bearer` interface.

Use it when you need:

- An OpenAI-compatible Chat Completions endpoint hosted in Germany
- Pay-per-token pricing with no minimum commitment
- GDPR data residency and an Auftragsverarbeitungsvertrag on request
- BYOK proxying to OpenAI / Anthropic / Mistral with PII redaction
- A managed Tavily web-search tool callable via standard tool-use
- CI-conformant PDF/DOCX generation from natural-language briefs

## Quickstart

```bash
curl https://api.simosphereai.com/v1/chat/completions \
  -H "Authorization: Bearer sk-simo-..." \
  -H "Content-Type: application/json" \
  -d '{"model":"qwen/qwen3-8b","messages":[{"role":"user","content":"Hello"}]}'
```
