Creative professionals rarely generate images one at a time. They work in focused sessions — exploring a concept, iterating on variations, adjusting parameters — then pause before starting something new. Session clustering detects these natural rhythms by analyzing timestamps, parameter continuity, and tool context.
The organizational value is significant: sessions become a middle layer between individual assets and the entire library. Users can browse by session ("Tuesday afternoon's character explorations") rather than scrolling through a flat chronological list. Sessions also provide context for lineage tracking — variations within a session are likely related even if their generation parameters differ substantially.
