Speeding Up the Agent › When Speed Isn't EverythingOne section · Sections in this chapter13 / 15 ↓

Before we wrap up, a word of caution: don't optimize prematurely. Speed is important, but accuracy matters more. If your agent gives wrong answers quickly, that's worse than giving right answers slowly.

Start by building a correct agent. Then measure where the bottlenecks are. Apply optimizations strategically, and always verify that accuracy doesn't suffer. Sometimes the best answer requires the most capable model and a longer response time. That's okay.

The goal isn't to make every response instant. It's to make the agent as fast as possible while maintaining the quality users expect.
