The Sora text-to-video model released by OpenAI has created a buzz, with some individuals using the Sora name to sell courses and accounts, and even committing fraud. Most of these courses and accounts are overpriced, with false content and no actual value. Some course sellers haven't even used Sora themselves; they are simply profiting from people's anxiety and information asymmetry. OpenAI has not yet opened access to Sora, and we remind everyone to be cautious to avoid getting scammed. It is advised to stay informed about new technologies like Sora.
