Tech Stack

• Framework: Next.js 14 (App Router)
• Language: TypeScript
• Styling: TailwindCSS
• UI: Shadcn UI
• AI: HuggingFace Inference API

Important: This project requires @huggingface/inference v4.13.5 or later. Earlier versions (v2.x) use the deprecated api-inference.huggingface.co endpoint which no longer works. The current version automatically uses the new router.huggingface.co endpoint.
