Claude can be given multiple tools and asked to perform a task. Which statement about parallel tool use is CORRECT?
Select an answer to reveal the explanation.
Short Explanation
When you give Claude independent sub-tasks, it can request multiple tool calls in a single response — like looking up two things at once instead of one at a time.
Full Explanation
Claude supports parallel tool use — when multiple tool calls are independent (they don't depend on each other's results), Claude can issue them simultaneously in a single response as multiple tool_use content blocks. The developer's application can then execute these calls in parallel and return all results at once. This can significantly improve latency for multi-tool workflows. The statement that Claude can only use one tool per conversation is wrong — Claude can use multiple tools across and within responses. The statement that parallel tool calls automatically make Claude's response 2x faster misunderstands how parallelism works — it depends on the application's execution, not a guaranteed multiplier. The statement that parallel tool use requires a special 'parallel_mode' API parameter is wrong — no special API parameter is needed.
