Capcom held its Capcom Open Conference RE: 2026 on October 2, where programmer Satoshi Ishida presented the REX project to evolve the RE Engine into what the company calls an "AI-generation game engine." The push comes after noting that modern game scale has made even small corrections and movement checks excessively time-consuming, while the growing number of developers requires an engine that is both human-friendly and AI-readable through a unified base language.

Ishida stated that successfully integrating AI technology into development procedures has become a prerequisite for streamlining future development, enabling AI to understand programs, automatically create them, and conduct test plays to check for bugs. Capcom has made some REX improvements open-source specifically for AI training purposes.

The stated goal is a future "where we create games together with AI," though the company reiterated its March 2026 position that it will not implement AI-generated assets into finished game content and intends to use the technology only for efficiency in areas like programming, graphics, and sound. This positions Capcom alongside other publishers integrating AI workflows while maintaining the public line on final product assets.
