• OpenAI CEO Sam Altman described that the company plans to add tens of thousands of GPUs in the coming weeks to meet demand. 
• The model’s hallucination rate stands at 37.1 per cent, compared to 61.8 per cent in GPT-4o and 44 per cent in OpenAI’s o1 reasoning model. 
• The model has been made available first to Pro users and developers worldwide. It will expand to ChatGPT Plus and Team users next week, followed by Enterprise and Edu users the week after.

Background
