01 · Problem

What made this interesting

Developers often need to compare multiple AI models across the same prompt, but existing tools provide limited transparency into model behavior, response quality, and performance. The goal was to build an interface that makes model evaluation intuitive while remaining scalable and extensible.

02 · Approach

How I solved it

Designed a modular architecture with a Next.js frontend and Django backend. Built a provider abstraction layer to support multiple LLM APIs, implemented streaming responses for a responsive user experience, and structured the application around reusable components to simplify adding new providers, evaluation workflows, and comparison features.

03 · Result

What came out of it

An actively evolving platform that provides a fast, interactive environment for comparing AI models while exploring modern frontend architecture, API integration, and developer experience.
