SAP generative AI hub is model management and orchestration for enterprise AI inside SAP AI Core, giving developers one API across hosted SAP models and partner models such as Anthropic Claude Sonnet 4, Google Gemini 2.5 Pro and OpenAI GPT-5, with prompt lifecycle management, an experimentation playground, automated prompt optimisation and inference observability. SAP does not publish list prices for it: the official trial page states the 30-day basic trial, after which the service is bought through Pay-As-You-Go for SAP BTP or an Enterprise Agreement, with pricing details routed to the SAP Discovery Center service catalogue. A page footnote states that token and after-promotion optimisation costs apply.
