Open-Source LLM Comparison Tool

vista8 · x · 2026-07-12

A developer used GPT 5.6 sol to build a "model PK arena" tool that allows users to compare outputs from multiple models using the same prompt. The tool supports Markdown rendering as well as HTML/SVG preview, making it ideal for comparing text generation and frontend web design tasks. Currently, the prompts are AI-generated, but the creator plans to curate hidden test cases shared by users on X. The project is open-source and offers an online demo.
