Hands-on: Experimenting with Prompts
LangChain allows you to test different prompt strategies with ease. You can dynamically insert variables into templates and observe how changing wording impacts results.
Code Sample:
Writing and testing different prompt styles
Try experimenting with:
• Open-ended vs. specific prompts
• Formal vs. conversational tone
• Short vs. detailed instructions
LangChain supports prompt chaining too, where the output of one prompt becomes input for the next — perfect for complex workflows and refining answers step-by-step.
What’s Next?
Now that you understand prompt engineering, you’re ready to build more intelligent, context-aware AI applications. In the next module, we’ll explore LangChain Chains and Agents — allowing your apps to reason, decide, and take actions like a real assistant.
