Jake Song Releases 32km Open MMO on GitHub as AI Agents Share Human Protocol

Jake Song, 58, has open-sourced his solo-developed MMORPG “Open MMO” on GitHub, framing it as a hobby project built over about seven months rather than a commercial game.
The project’s core design makes AI agents and human players connect through the same WebSocket protocol, giving agents no special API access and leaving the server unable to distinguish between them.
Song said AI-driven “vibe coding” let him execute ideas he had shelved for 30 years, with models now handling most coding, review and even some 3D asset work for costs that rose from $20 plans to about $200.
Open MMO follows classic Ultima-style conventions with a procedurally generated 32km-by-32km world, seven classes and dice-roll stat allocation, while Song highlighted AI’s limits in spatial tasks like multi-story stairs and water rendering.
He cast the release as evidence of a broader labor shift, arguing AI already outperforms many midlevel programmers and is starting to erode entry-level paths across white-collar work.
