Blackbox AI now presents itself as enterprise inference rather than a consumer coding tool: its pricing page shows a single Enterprise plan with custom, annual, purchase-order committed spend and no free or individual tiers. Pricing is per token against published list rates across a 300+ model catalog served from one OpenAI-compatible endpoint, for example deepseek-v4.1-flash at $0.15 input / $0.60 output per 1M tokens and kimi-k3 at $3.00 / $15.00 per 1M, with commitments drawn down as usage is consumed and spend alerts at 75% and 90%. The same pages state end-to-end encryption on every connection, contractual zero data retention, PII removal before prompts reach closed models, dedicated single-tenant deployment and implementation included at $0 with a forward-deployed engineer.

No free tier stated on official pages (blackbox.ai, blackbox.ai/pricing and docs.blackbox.ai all present enterprise per-token commits only, checked 2026-09-16).

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).
