ReasoningProv1.0.0
What a model did before it answered, kept to one quiet line: Thinking with a running clock while it works, its steps open to watch them land, then Thought for 12s with the steps folded away. Each step is waiting, working, done or failed.
pnpm dlx shadcn@latest add @beautiful-ui-pro/lumen-reasoningNeeds your registry key. Your components.json style picks the Base UI or Radix build: radix-*, new-york and default get Radix, base-* gets Base UI.
Styles didn't apply?
The CLI adds the styles to the CSS file named in components.json (tailwind.css). Check that it points at your global stylesheet, that the project uses Tailwind CSS v4, and that the file is imported in your root layout. Installed by hand: paste styles.css into that file.
Usage
Import it and pass your content. The props that matter most are listed next.

import { Reasoning, type ReasoningStep } from "@/components/ui/lumen/controls/reasoning";
export function ReplyThinking({ steps, thinking, startedAt }: { steps: ReasoningStep[]; thinking: boolean; startedAt: number }) {
return <Reasoning steps={steps} thinking={thinking} startedAt={startedAt} />;
}
// Steps as your model reports them:
export const example: ReasoningStep[] = [
{ id: "read", label: "Read the March invoices", detail: "212 invoices, 3 currencies", status: "done" },
{ id: "match", label: "Match payments to invoices", status: "active" },
{ id: "flag", label: "Flag anything unpaid after 30 days", status: "pending" },
];Props
