For ChatGPT, accessing its capabilities definitely requires an account. Users must sign up with an email address or a Google/Microsoft account to use even the free tier powered by GPT-3.5, and a separate subscription is needed for GPT-4.

Both platforms offer various tiers, with a free version generally available after account creation, and premium subscriptions offering advanced features and capabilities.
