Where this model earns its place
function calling
Tool use and structured output — dependable JSON for agent loops, RAG pipelines, and workflow automation.
reasoning
Multi-step reasoning — planning, quantitative analysis, and problems that need deliberation rather than recall.

Data handling
Requests are processed in the EU. Prompts are not used for training, and logs follow the retention period in your contract — zero-retention is available on request.
