Open-Fiesta is an open-source AI chat playground built with Next.js App Router, designed for users who want to experiment with multiple AI models and providers. It allows users to compare outputs side-by-side, offers web search and image attachment capabilities, and provides a clean, user-friendly interface.

How It Works

The project leverages Next.js 14 with the App Router and Tailwind CSS for its tech stack. It utilizes API routes to normalize responses from various providers, including Gemini and OpenRouter (which aggregates models like DeepSeek R1, Llama 3.3, Mistral, and others). A key design choice is the normalization of API responses and post-processing of specific model outputs (like DeepSeek R1) to enhance readability and consistency across different AI models.

Quick Start & Requirements

1. Install dependencies: npm i
2. Configure environment: Create a .env.local file with OPENROUTER_API_KEY and/or GOOGLE_GENERATIVE_AI_API_KEY.
3. Run development server: npm run dev
