⚡ Python to C++ High-Performance Code Converter

A web-based tool that converts Python code into high-performance C++ using LLMs (GPT-4o / Claude 3.5). It also lets you run and compare outputs of both Python and the optimized C++ implementation.

🚀 Features

• Convert Python functions to optimized, low-latency C++.
• Support for OpenAI GPT-4o and Anthropic Claude 3.5 Sonnet models.
• Live code execution and output comparison for both Python and C++.
• Built-in web interface powered by Gradio.
• Auto-generates optimized.cpp and compiles using Clang with performance flags.
• Stylish, modern UI with clean execution results.
