Saber denies replacing Rideshare Stimulator’s writers with ChatGPT

Matthew Karch, CEO of Saber Interactive, has issued a denial following claims that the studio replaced human writers with ChatGPT during the development of Rideshare Simulator. The company states that neither Saber nor its partner Unigine substituted any staff with artificial intelligence for the title announced last month. This response comes after Stella Sacco, a former lead writer on the project, publicly stated on Bluesky that she was replaced by the tool midway through production. Sacco further alleged that all passenger voices within the game were also generated by AI, suggesting a shift in direction or a lack of transparency regarding the final Steam release.

The dispute highlights the friction between developer assurances and the lived experience of former employees regarding modern production pipelines. While Saber maintains that its workforce remains intact, the specific nature of Sacco’s claims touches on the extent of automation in voice acting and narrative design. The situation raises questions about how studios manage internal communications and public disclosures when integrating generative tools into complex simulation games.

  • Sacco identified herself as the original lead writer for the project.
  • She claimed passenger dialogue was fully AI-generated.
  • The game is set to launch on Steam shortly.
