A16z posted AI-generated TikTok character without disclosure

• Olivia Moore at venture firm A16z created a fake 19-year-old named Janie using ChatGPT images, Minimax 3 video generation, Grok voice, and ElevenLabs audio.
• Twenty videos posted to TikTok reached 1,300 followers and nearly 100,000 views on the first video before viewers identified her as artificial by day two.
• The videos contained no disclosure that Janie was AI-generated, violating platform requirements for synthetic media labeling.
• Despite detecting the fake, viewers continued watching, suggesting AI character creation works technically but disclosure and storytelling remain crucial for audience trust.

Olivia Moore at A16z built a fictional 19-year-old named Janie using ChatGPT images, Minimax 3 video, Grok Imagine 1.5, and ElevenLabs voice, then posted 20 videos to TikTok without AI disclosures. Janie reached 1,300 followers and nearly 100K views on her first video before viewers spotted the fake by day two, but kept watching anyway. The newsletter argues this shows AI can manufacture characters but human taste, storytelling, and transparent disclosure still determine whether people actually care.
