A session groups events related to long-term user interactions and can include multiple traces, with each trace potentially having many LLM requests. In a chatbot, a session might represent the whole conversation, while for an agent, it might cover a single task execution. The session’s scope depends on your application’s needs. Baserun uses a session identifier to organize traces and LLM requests into sessions.
