ChatGPT-maker OpenAI\u2019s upcoming model could be as much as 20 times more costly than its predecessor but will be far more creative and \u201cnatural\u201d in its conversational style, according to OpenAI and early testers.\u00a0\u00a0<\/p>\n
OpenAI released a research preview of GPT-4.5 on Feb. 27, its most advanced AI model, which can recognize patterns, draw connections, and make creative insights without reasoning in a superior way to earlier versions, the company said.<\/p>\n
OpenAI said GPT-4.5\u2019s broader knowledge base and improved \u201cEQ\u201d (emotional intelligence) make it more useful for creative tasks and solving practical problems, OpenAI said<\/a> in a Feb. 27 statement.<\/p>\n \u201cWe also expect it to hallucinate less and deliver more reliable performance across a wide range of general topics, including richer conversations.\u201d<\/p><\/blockquote>\n Source: <\/em>OpenAI<\/em><\/a><\/p>\n<\/figcaption><\/figure>\n GPT-4.5\u2019s enhanced creativity and more \u201cnatural conversational style\u201d means it isn\u2019t well-suited to perform detailed step-by-step logic \u2014 at least compared to OpenAI\u2019s o-series-models,<\/a> it added.\u00a0<\/p>\n The trade-off is that it lacks \u201cchain-of-thought reasoning and can be slower due to its size,\u201d the firm said. It also doesn\u2019t produce multimodal output like audio or video.\u00a0<\/p>\n OpenAI\u2019s latest model received a similar review<\/a> from Dan Shipper, CEO of AI and the business newsletter Every.<\/p>\n \u201cIt\u2019s not going to blow your mind, but it might befriend you,\u201d Shipper said, who said his firm has been testing the latest version for a few days.<\/p>\n \u201cIt\u2019s more like a personality, communication, and creativity upgrade than a huge intelligence leap. It\u2019s like OpenAI is pivoting its base model from \u2018bland assistant\u2019 to \u2018AI bestie.\u2019\u201d<\/p><\/blockquote>\n Shipper also said GPT-4.5 is \u201csometimes worse\u201d at following instructions.\u00a0<\/p>\n AI researcher Aran Komatsuzaki also said<\/a> that GPT-4.5 costs around 15 to 20 times more than GPT-4o to access the API.
