Imagine an AI agent needs to check the weather, fetch news, and get stock prices. Should it call these tools one-by-one (sequential) or all-at-once (parallel)? The difference can be 3x faster execution!
Why This Matters

Sequential (Slow)
Call tool 1 → wait → call tool 2 → wait → call tool 3
3 seconds total

Parallel (Fast)
Call all 3 tools at once → wait for slowest

When to Use Parallel Tool Calling
✓
Tools are Independent
Each tool's input doesn't depend on another's output
✓
I/O Bound Operations
API calls, database queries, file operations
✓
Speed Matters
User experience depends on fast responses
