The goal of this project is to show how we can use langchain4j to create an application based on AI/LLM.
It is a simple use case:
- We have a travel booking assistant.
- We can chat to him to specify our travel wishes and when he has all the information, the application invokes a service to book the trip.
- You can also ask the assistant for the weather forecast for your holiday destination (another service is invoked in this case).
For this application, we use:
- annotations provided by langchain4j:
@Tool(to describe the service that can be invoked) and@SystemMessage(to describe the context) - OpenAI as the chat language model
In the following example, we can see the chat, the service invocations when the assistant has the required data:
