Obviously, the Pro plan and its new model aren't designed for casual ChatGPT use. Beyond the high recurring costs, o1 Pro is relatively slow in responding, as it prioritizes accurate results. The tier is better suited for researchers and certain power users who actually need the added smarts despite the associated compromises.
To access ChatGPT Pro and its exclusive perks, you can pay OpenAI directly on the official website. If you prefer Apple App Store or Google Play Store billing, you can pay the same fee using the updated mobile app. Notably, the company warns that sharing your login credentials with others violates its terms of service. So, using the same ChatGPT Pro account and splitting the fee among multiple people could get your account restricted.
