This is a PHP-based web application that wraps third-party AI APIs (DeepSeek for text chat, Stable Diffusion for image generation) into a user-friendly interface. It uses Server-Sent Events for streaming responses that appear in real-time. The frontend supports Markdown rendering with code syntax highlighting, math formulas, and mobile-responsive design. It includes context-aware multi-turn conversations and preset prompts, all bundled in a lightweight single-file implementation without frameworks.
