Summary
After setting up our development environment and configuring necessary API keys, we’ve explored the foundations of LangChain development, from basic chains to multimodal capabilities. We’ve seen how LCEL simplifies complex workflows and how LangChain integrates with both text and image processing. These building blocks prepare us for more advanced applications in the coming chapters.
In the next chapter, we’ll expand on these concepts to create more sophisticated multimodal applications with enhanced control flow, structured outputs, and advanced prompt techniques. You’ll learn how to combine multiple modalities in complex chains, incorporate more sophisticated error handling, and build applications that leverage the full potential of modern LLMs.
