"OpenAI's GPT-4.5: A Leap in AI, But at What Cost?"

OpenAI's upcoming GPT-4.5 model, set to be released soon, is expected to be a significant leap forward in AI capabilities. According to the company and early testers, the new model will be more creative and "natural" in its conversational style, while also being more emotionally intelligent and better equipped to handle practical problems.

GPT-4.5, which is expected to be around 20 times more expensive than its predecessor, will have a broader knowledge base and improved emotional intelligence, making it more useful for creative tasks and problem-solving. The model is also expected to hallucinate less and deliver more reliable performance across a wide range of general topics, including richer conversations.

However, the new model may not be as well-suited for detailed step-by-step logic as OpenAI's o-series models. It lacks chain-of-thought reasoning and can be slower due to its size. Additionally, it does not produce multimodal output like audio or video.

Early reviews of GPT-4.5 have been mixed. While some, like Dan Shipper, CEO of AI and the business newsletter Every, describe it as a "personality, communication, and creativity upgrade," others, such as AI researcher Aran Komatsuzaki, note that it costs around 15 to 20 times more than GPT-4 to access the API.

OpenAI CEO Sam Altman admitted that the new reasoning model "won't crush benchmarks" and is a "giant expensive model." However, he also noted that the cost to build these AI models is falling rapidly, with the price per token dropping about 150x in the time period from GPT-4 to GPT-4o.

In the medical field, GPT-4.5 has shown remarkable potential. Professor Derya Unutmaz of The Jackson Laboratory claimed that the model correctly identified a tubal ectopic pregnancy in a medical image, while other AI models, such as Grok 3, Claude 3.7 Sonnet, and Gemini 2.0, mistakenly identified it as a normal pregnancy.
