One of the biggest game engines in the industry is being powered by AI
Epic continues to be all-in on AI. In a recent statement to This Week In Video Games, Epic’s executive VP of development Marcus Wassmer clarified the specifics around how the company is using AI for Unreal Engine 6, Fortnite, and just about everything else at the company.
“Yes, we are vibe-coding things. That means our engineers are no longer writing the bulk of the code, but they are still guiding the tools to get the architectural result we want," Wassmer said. "We’re not ‘one-shotting’ the engine; we’re iterating with AI to ship features developers want and keep the engine within the memory, performance, and scalability envelopes.”
“We are more concerned about the risks of moving too slowly than we are about AI skepticism,” Wassmer added. While the move is unsurprising given how outspoken Epic CEO Tim Sweeney has been in favor of generative AI, it marks a shift from where Epic was just a year ago, when Sweeney denied the company was using AI for Unreal Engine updates. The concept that the new version of one of the most-used video game engines was “vibe-coded” by AI, and thus may not be fully understood by Epic, has been met with alarm by many game developers. Others have pointed out that there's little reason they don't just vibe-code their own engine instead of paying Epic's hefty licensing fees.
Earlier this month, Epic revealed that it “vibe-coded” a new version of the Epic Games Store launcher.
