AI infrastructure and model inference pricing
The layer between a foundation model and an application: vector databases for retrieval, agent frameworks for orchestration, and inference providers that serve open-weight models by the token. Pricing here is usage-based almost without exception, metered by tokens, queries or storage rather than sold as a flat monthly seat.
