+        Enable automatic prompt caching. When set at the top level, the system automatically applies cache breakpoints to the last cacheable block in the request. When set on an individual content block, it marks an explicit cache breakpoint; block-level markers also work on OpenAI models that support explicit prompt caching — OpenRouter converts them to the provider's native format.

+        Marks an explicit prompt-cache boundary on this content block (OpenAI-style). Everything through the block carrying this marker is part of the candidate cached prefix. Supported natively by OpenAI GPT-5.6 and newer; on providers that use Anthropic-style `cache_control`, OpenRouter converts the marker to that format automatically.
