    role: JsonValue; "assistant"constant"assistant"constant

    Conversational role of the generated message.

    This will always be "assistant".

    Accepts one of the following:
    ASSISTANT("assistant")
    stopReason: Optional<BetaStopReason>

    The reason that we stopped.

    This may be one the following values:

    • "end_turn": the model reached a natural stopping point
    • "max_tokens": we exceeded the requested max_tokens or the model's maximum
    • "stop_sequence": one of your provided custom stop_sequences was generated
    • "tool_use": the model invoked one or more tools
    • "pause_turn": we paused a long-running turn. You may provide the response back as-is in a subsequent request to let the model continue.
    • "refusal": when streaming classifiers intervene to handle potential policy violations

    In non-streaming mode this value is always non-null. In streaming mode, it is null in the message_start event and non-null otherwise.

    Accepts one of the following:
    END_TURN("end_turn")
    MAX_TOKENS("max_tokens")
    STOP_SEQUENCE("stop_sequence")

    stopSequence: Optional<String>

    Which custom stop sequence was generated, if any.

    This value will be a non-null string if one of your custom stop sequences was generated.

    type: JsonValue; "message"constant"message"constant

    Object type.

    For Messages, this is always "message".

    Accepts one of the following:
    MESSAGE("message")
    usage: BetaUsage

    Billing and rate-limit usage.

    Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.

    Under the hood, the API transforms requests into a format suitable for the model. The model's output then goes through a parsing stage before becoming an API response. As a result, the token counts in usage will not match one-to-one with the exact visible content of an API request or response.

    For example, output_tokens will be non-zero, even for an empty string response from Claude.

    Total input tokens in a request is the summation of input_tokens, cache_creation_input_tokens, and cache_read_input_tokens.

    cacheCreation: Optional<BetaCacheCreation>

    Breakdown of cached tokens by TTL

    ephemeral1hInputTokens: Long

    The number of input tokens used to create the 1 hour cache entry.

    minimum0

    The number of input tokens used to create the 5 minute cache entry.

    minimum0
    cacheCreationInputTokens: Optional<Long>

    The number of input tokens used to create the cache entry.

    minimum0
