GPT-5.6 Sol designs custom CPU running Doom in Turing Complete sandbox

AI-Designed CPU Runs Doom

An AI computing enthusiast, Angel (@Angaisb_), successfully demonstrated the classic game Doom running on a custom CPU. This CPU, dubbed 'Codex-R32', was designed by the AI model GPT-5.6 Sol. The demonstration took place within the sandbox environment of the game Turing Complete.

Technical Implementation

The 'Codex-R32' CPU was constructed from primitive logic components available within Turing Complete. The Doom implementation used the C-based PureDOOM port, which was compiled into native RV32IM machine code to run directly on the custom AI-designed CPU. The performance was not described as playable, but the functionality was confirmed.

Visual Demonstration

The demonstration included a video showing the game's viewport overlaid on a pulsing schematic of the custom CPU. This schematic provided a live visualization of processor gates, registers, memory, and ALUs, along with live statistics such as cycle counter, simulation speed, and memory/register values, all within the Turing Complete environment.

Implications for AI and Hardware Design

This achievement highlights the capability of large language models like GPT-5.6 Sol to not only generate software but also to design functional virtual hardware. The successful execution of Doom, a common benchmark for computing capabilities, suggests a notable step in AI's ability to create complex system architectures.
