Column Chat generalizes the chat interface from two columns to many. Each column declares which other columns it reads and how much history it sees, forming a dataflow graph. Context fans out to columns that each maintain their own focus, then merges back together — bringing programming concepts like reducers and fan-out/fan-in to LLM conversations. The structure is static and visible: you see exactly what each column receives, edit it live, and add columns mid-conversation that backfill from the start. You can also describe a pipeline in plain language and Opus 4.6 generates the full column configuration.
