Struct OpenAIPromptCacheSettings 

pub struct OpenAIPromptCacheSettings {
    pub enabled: bool,
    pub surface_metrics: bool,
    pub prompt_cache_key_mode: OpenAIPromptCacheKeyMode,
    pub prompt_cache_retention: Option<PromptCacheRetention>,
    /* private fields */
}

OpenAI prompt caching controls (automatic with metrics)

Fields

enabled: bool

surface_metrics: bool

prompt_cache_key_mode: OpenAIPromptCacheKeyMode

Strategy for generating OpenAI prompt_cache_key. Session-scoped keys derive one stable key per VT Code conversation.

prompt_cache_retention: Option<PromptCacheRetention>

Optional prompt cache retention policy to pass directly into OpenAI Responses API. Supported values are “in_memory” and “24h”. If set, VT Code will include prompt_cache_retention in the request body to extend the model-side prompt caching window or request the explicit in-memory policy.
