OpenAI announced ChatGPT Pro, a $200 monthly subscription offering enhanced access to its most powerful AI models, including o1 pro mode, which boasts improved accuracy and reliability, especially for complex tasks in data science, programming, and legal analysis. This improved performance is demonstrated through benchmark comparisons against previous models. Ten ChatGPT Pro grants are being awarded to medical researchers to accelerate their work.
