OpenAI has introduced o1-pro, its most advanced AI model, now available through its developer API. This model promises superior performance, utilizing greater computing power than its predecessor, o1. Priced at $150 per million tokens for input and $600 for output, it’s significantly more costly than previous models. Currently accessible to select developers, o1-pro aims to deliver more reliable responses. However, early user feedback indicates mixed results, with issues noted in solving puzzles and answering basic queries. OpenAI hopes its enhanced capabilities will justify the high costs for developers.
