OpenAI spends about $700,000 a day, just to keep ChatGPT going. The cost does not include other AI products like GPT-4 and DALL-E2. Right now, it is pulling through only because of Microsoft's $10 billion funding
ChatGPT has the potential to make Bing relevant and unseat Google. No way Microsoft pulls funding. Sure, they might screw it up, but they'll absolutely keep throwing cash at it.
