displayName
Supports prompt caching
description
The entity supports an explicit prompt-caching surface where parts of
the prompt (system messages, tool definitions, large context blocks)
are marked for cache reuse and billed at a reduced rate on cache hits.
Anthropic exposes this via `cache_control` blocks on Messages API;
OpenAI and Gemini have related but distinct surfaces.
