OpenAI introduces an upgraded GPT-4 Turbo for premium ChatGPT users, boasting enhanced writing, math, logic, and coding abilities. Trained on data up to December 2023, it promises more concise and conversational responses. The update follows OpenAI's recent API launch featuring GPT-4 Turbo with Vision. However, the company faces scrutiny after reports of DALL-E's military application and internal controversies leading to researcher dismissals.
