Properties

CacheCreationTokens

Tokens written to cache for future reuse (Anthropic only). Mapped from: Anthropic cache_creation_input_tokens.

public int CacheCreationTokens { get; set; }

Property Value

int

CacheHitRatio

Cache hit ratio (0.0 to 1.0). Returns 0 if no input tokens.

public double CacheHitRatio { get; }

Property Value

double

CachedInputTokens

Input tokens served from cache (reduced cost). Mapped from: Anthropic cache_read_input_tokens, OpenAI cached_tokens, DeepSeek prompt_cache_hit_tokens, Gemini cachedContentTokenCount.

public int CachedInputTokens { get; set; }

Property Value

int

HasCacheActivity

Whether any cache activity occurred (hit or creation).

public bool HasCacheActivity { get; }

Property Value

bool

InputTokens

Number of tokens in the input/prompt

public int InputTokens { get; set; }

Property Value

int

NonCachedInputTokens

Input tokens that were NOT served from cache.

public int NonCachedInputTokens { get; }

Property Value

int

OutputTokens

Number of tokens in the output/completion

public int OutputTokens { get; set; }

Property Value

int

ReasoningTokens

Tokens used for internal reasoning/thinking. Mapped from: OpenAI reasoning_tokens, Gemini thoughtsTokenCount.

public int ReasoningTokens { get; set; }

Property Value

int

TotalTokens

Total tokens used (input + output)

public int TotalTokens { get; set; }

Property Value

int

VisibleOutputTokens

Output tokens excluding reasoning (visible output only).

public int VisibleOutputTokens { get; }

Property Value

int
