@envatoMost AI tools expect you to know exactly what you want. But creative work often starts with a brief, a reference, or just a hunch. That’s why we built Burst mode. Turn the start of an idea into up to six image directions at once, up to 10× faster, for just one AI credit. More https://t.co/iuDHCL5q3l

@OpenAIWe're sharing progress on ChatGPT for Teens, our ChatGPT experience for people under 18, alongside a preview of College Planner, new study tools, and support for college advisers and teen voices. ChatGPT for Teens applies automatically to accounts identified as belonging to someone under 18, with protections on by default. Coming soon: College Planner brings application requirements, deadlines, tasks and financial-aid steps together for high school students in the U.S. planning to attend a four-year college. We'll keep building these tools, evaluating how they and their protections work in practice, and sharing what we learn. https://t.co/wtiMeor5yh
