Langchain and similar open source frameworks for building language model based applications are probably as popular as those language models: ChatGPT, GPT-4, etc. But how approachable and useful are those frameworks? At the same time prompt engineering is presented as something that can be easily implemented, used by non-developers and developers alike, and light-weight. How powerful is it?

Let's talk about scenarios when it's better to use Langchain and when a good prompt can be enough. Veronika will use her personal projects as examples, and you are welcome to share your experience as well.

You will learn:

• Insights into prompt engineering and its ease of implementation and usage
• When to choose Langchain or other frameworks over prompt engineering for specific projects
• About real-life examples to better understand the practical application of the tools
