About

Standalone model picker pill button with built-in popover. Renders model name + version split (e.g. Sonnet 4.6). Supports controlled and uncontrolled modes. Self-contained port from 21st.dev Agent Elements.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Model Picker to your project and fits it to your theme.

Code

How Model Picker is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

import { ModelPicker, type ModelOption } from "@/components/ui/model-picker";
import { IconArrowUp } from "@tabler/icons-react";

const models: ModelOption[] = [
  { id: "sonnet-4-6", name: "Sonnet", version: "4.6" },
  { id: "opus-4-7", name: "Opus", version: "4.7" },
  { id: "haiku-4-5", name: "Haiku", version: "4.5" },
];

export default function Demo() {
  return (
