For example, if you need very precise, factual answers, you might choose an LLM known for its accuracy. If you need something more conversational, a different LLM might be better. Don’t be afraid to try a few different models. See which one gives you the best results for your specific use case. This smart choice makes your AI agents perform better.
Testing and Iterating Your AI Agents
Building AI agents is often a process of trying things out and making them better. You won’t get it perfect on the first try, and that’s okay. Test your agent often with different inputs. See how it responds. Does it give the answers you expect? Does it handle unexpected questions well?
When you find something that isn’t quite right, make small changes. Then, test again. This is called ‘iteration.’ It’s how you refine your agent over time. Keep track of what works and what doesn’t. This helps you learn and improve your AI agents continuously. It’s a vital part of developing robust applications with ADK for Java.
Ensuring Robustness and Error Handling
Your AI agents should be able to handle unexpected situations. What happens if an LLM returns an error? Or if a user asks something totally off-topic? Good practices include planning for these cases. You’ll want to add code that catches errors gracefully. This prevents your application from crashing.
Think about how your agent can recover or give a helpful message. This makes your AI agents more user-friendly and reliable. It builds trust with your users.
