type CacheHint 

type CacheHint struct {
	// Enabled marks this content as a cache breakpoint candidate.
	// For Anthropic/Bedrock: emits cache_control / cachePoint at this position.
	// For OpenAI: no-op (caching is automatic).
	Enabled bool `json:"enabled,omitempty"`

	// TTL requests a specific cache duration.
	// Valid values: "" (provider default, typically 5m), "5m", "1h".
	// The "1h" option requires a supporting model (Claude Haiku/Sonnet/Opus 4.5+).
	TTL string `json:"ttl,omitempty"`
}

CacheHint requests provider-side prompt caching for a message or request. It is a provider-neutral instruction: Anthropic and Bedrock translate it to explicit cache breakpoints on content blocks; OpenAI caching is always automatic and ignores per-message hints, but honours TTL on Request.CacheHint.
