THE NEXT GREAT LEAP IN AI IS BEHIND SCHEDULE AND CRAZY EXPENSIVE

Summary from the TLDR newsletter

OpenAI's GPT-5 project is expensive and behind schedule. It isn't clear when, or if, it will work. Microsoft had expected to see the model around mid-2024. There may not be enough data to train the model to make it smart enough. OpenAI recently turned to a technique called 'reasoning' to make its large language models smarter. It just released a new reasoning model smarter than anything else the company has released before, but there is still no word on when GPT-5 is coming.
