# Split pane model comparison running one prompt against two AI models

> Side by side compare view: two resizable panes answer one docked prompt and stream at different speeds, with sortable data tables in the replies, a scroll lock that reads both answers at the same depth, and per answer copy and rating actions. Select a line to ask both models about it, regenerate or swap either pane, attach extra files, and watch a mirrored scoreboard for latency, output rate and cost settle into a verdict with an A or B vote.
