Client-generated identifier for usage accounting. Reset starts a new conversation with a new identifier.

Most recent final assistant response, or null before the first completed turn.

Maximum batches of tools executed during one Send, including its retries. Defaults to 30. If the limit is reached, increase it before Retry to continue the pending turn.

User messages and final assistant replies acknowledged by this instance, in order. A queued user message appears once the first assistant response is received.

Total credits charged for this chat, or null when accounting is unavailable or incomplete. Refreshed by assistant and server-tool responses.

Starts a fresh local conversation with the same instructions and tool callbacks. Clears history, pending requests and usage. Use this to recover from a permanently rejected request. Game actions already performed by tools are not undone.

Resumes an interrupted Send using its retained conversation history. Completed tool callbacks are not rerun. A callback cancelled during execution is retained as a tool error rather than rerun; cancellation does not undo game actions already performed by a callback or server processing. A response lost in transit may be generated and charged again on retry.
