👉 Session Fluid is a type of token used in the context of transformer models, particularly for handling dynamic session IDs that change during a conversation or interaction. It allows the model to maintain context across multiple turns in a dialogue without needing to store all previous interactions in memory, thus optimizing efficiency and scalability. Unlike static session IDs, Session Fluid is generated on-the-fly for each session and can be reused across different interactions within the same session, ensuring that the model retains relevant context while minimizing resource usage.
