GPT-4.5: Open AI new successor.

New open AI spend a significant amount of time thinking about a question before answering, rather than providing an instant response.

“What sets the model apart is its ability to engage in warm, intuitive, naturally flowing conversations, and we think it has a stronger understanding of what users mean when they ask for something,” said Mia Glaese, vice president of research at OpenAI. GPT 4.5 prime goal is to build systems that can carefully and logically solve a problem through a series of discrete steps, each one building on the last, similar to how humans reason. These technologies could be particularly useful to computer programmers who use A.I. systems to write code. OpenAI says that GPT-4.5’s increased size has given it “a deeper world knowledge” and “higher emotional intelligence.” However, there are signs that the gains from scaling up data and computing are beginning to level off. On several AI benchmarks, GPT-4.5 falls short of newer AI “reasoning” models from Chinese AI company DeepSeek, Anthropic, and OpenAI itself.

OpenAI said that, beginning Thursday, GPT-4.5 would be available to anyone who was subscribed to ChatGPT Pro, a $200-a-month service that provides access to all of the company’s latest tools
