AI-Written Rust Engine Phargo Passes 17% of PHP Tests and Supports WordPress
Key points
- Phargo is an AI-built PHP engine written in Rust.
- It successfully renders a WordPress front page.
- The engine passes 17.4% of PHP's 22,000 test cases.
Overview of Phargo
Phargo is a newly developed PHP interpreter entirely constructed in Rust. Unique to this project is that it contains no actual PHP source code, relying on AI for its code generation. Despite the author's lack of experience with Rust, their AI's output rendered a basic WordPress site.
The Testing Methodology
To evaluate Phargo's functionality, the experiment utilizes the standard PHP test suite comprising nearly 22,000 tests established over three decades by the PHP internals team. This approach ensures that the AI does not self-evaluate, creating a reliable measure of performance.
Performance Results
Currently, Phargo has achieved a pass rate of 17.4%, successfully completing 3,844 out of 22,037 tests. This score represents substantial progress from the initial performance, which began at zero. The expected maximum pass rate is around 40-45%, factoring in tests related to C extensions that fall outside the project's scope.
Implications for AI and Development
The Phargo project illustrates the potential of AI-assisted coding and development tools in creating functional software from scratch. While the 17% success may seem modest, it showcases a viable path for AI-generated interpreters, hinting at future improvements. The results highlight a growing intersection of AI with traditional programming paradigms.
