THEN Default to Claude Opus 4.7 via the exact model string 'claude-opus-4-7'. Use adaptive thinking (thinking: {type: 'adaptive'}) for anything remotely complicated. Default to streaming for any request that may involve long input, long output, or high max_tokens; use the SDK's .get_final_message() / .finalMessage() helper to get the complete response if not handling individual events.
