ChatAnywhere is a widely used free LLM relay. Users bind a GitHub account to get a free API key and access GPT-4o, Claude, and Gemini models through an OpenAI-compatible interface, optimized for access from mainland China.

GitHub-bound free key: 10,000 points/day with per-model caps (GPT-5/4o/4.1 5/day, DeepSeek 30/day, mini models 100/day, ~200 req/day total) ≈ $2/mo; personal non-commercial use only.

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.

SAP offers a 30-day basic trial of generative AI hub with no dollar credit value stated on the official trial or product pages; it is a time-boxed licence grant, not a cash allowance (checked 2026-09-16).
