MetaGPT setup: generate a Snake game with GPT-4

Uploaded on August 14, 2023, this tutorial demonstrates MetaGPT on Windows. The presenter also reports testing it on Mac. No MetaGPT version is specified; the setup uses Python 3.11.4 and configures GPT-4, with GPT-3.5 suggested for viewers without access. These instructions describe the setup at the time of upload.

MetaGPT assigns software development tasks to roles such as product manager, architect, engineer and QA. The presenter uses this AI agent to generate requirements, a PRD and code from a prompt for a Snake game based on Pygame. Although the software runs on the user's machine, the demonstrated configuration calls OpenAI through an API key rather than using a local LLM.

The walkthrough creates a Conda environment, installs npm and Mermaid CLI, clones the repository and installs Python dependencies. The presenter runs both the requirements installation and the setup script because that combination worked in his tests. A missing bs4 module interrupts the first attempt, which he resolves with a separate installation.

The generated game runs, but the snake can leave the map. Document output also differs: the presenter reports PNG and PDF files on Mac, while the Windows run produces a Markdown PRD. He describes an optional code review flag as adding iterations and cost, but does not enable it. At the time, he says MetaGPT could not iterate on existing code.
