The Sora app has been shut down. Early on, there was even talk that it might become the next TikTok. In Feb, Sora had around 21.93 million MAU (ChatGPT has 500M), which is obviously still a long way from TikTok’s 1 billion MAUs. That said, its performance wasn’t actually bad for an AI product. It ranked 52nd among all AI products, ahead of Manus and just behind Moltbook (if bot users are included). In the video generation category, it even ranked #1. Despite this, it was still shut down. likely because it consumed enormous amounts of compute while generating little revenue. The company probably decided it needed to focus its resources on LLMs to better compete with rivals like Anthropic. So in that sense, we probably should cut Farcaster some slack. “Building new retentive social networks is still hard”, no matter the reason.
