OpenAI has temporarily restricted ChatGPT's new AI image generation feature due to overwhelming demand, which has caused the company's GPUs to overheat. CEO Sam Altman revealed that to manage the load, free-tier users will now be limited to three image generations per day. The feature, initially launched without restrictions, has seen unexpected popularity. Altman noted the need for efficiency improvements to prevent further GPU issues. OpenAI continues to develop its AI capabilities, with more updates on the horizon, including plans for GPT-4.5 and GPT-5 enhancements.
