Hy3, a free model accessible via OpenRouter, demonstrated strong code generation by creating a functional, visually polished flight simulator from a natural language prompt in a single HTML file. The output showcases the model's ability to produce interactive web applications with minimal instruction.
A user on the r/LocalLLaMA subreddit highlighted the coding capabilities of Hy3, which is available for free through OpenRouter. The model was asked to build a "beautiful, relaxing flight simulator" on a single HTML page.
The finished project, posted on CodePen, delivers an interactive and fully working experience. It was run with the opencode harness in an empty environment, showing that the model can produce complex web apps from a simple prompt without external dependencies.
