Google's AI somehow knew a game secret that existed only in a private Google Doc

Key Points:

• An indie developer of the game Operation Octo discovered that Google's AI revealed a character name, "Vantage Tripod," which existed only in a private Google Doc and had never been publicly shared or included in the game's code or files.
• The developer found this alarming because the game has a limited online presence, making it unlikely that the AI could have learned the character name from public sources or online speculation.
• Google stated that private Workspace content, including Drive files and Docs, is not used to train its AI models, though publicly shared documents can be indexed if accessible via search crawlers.
• Attempts to replicate the AI's original response failed, and subsequent searches began citing the Reddit post discussing the leak as the source, complicating efforts to verify how the AI generated the information.
• The incident highlights challenges for AI search systems in distinguishing between reliable sources and public rumors, emphasizing the need for transparency about the origins of obscure information in AI-generated answers.
