OpenAI has introduced two subscription tiers for ChatGPT: Plus, priced at $20 per month, and Pro, which costs $200 per month, with the latter offering advanced features and fewer limitations.

The newly launched Deep Research feature, initially exclusive to Pro users, is now accessible to Plus subscribers, albeit with some restrictions.

ChatGPT Plus users are limited to just 10 Deep Research reports per month, a stark contrast to Pro users who face no such limits.

While GPT-4.5 is fully accessible to premium users, Plus subscribers experience limitations compared to Pro users.

The usage limits for GPT-4.5 are less transparent, lacking a straightforward method for users to check them, which may lead to confusion.

A long-time ChatGPT Plus subscriber has expressed satisfaction with the service but is hesitant to upgrade to the Pro tier due to a perceived lack of value.

To enhance user experience, pop-up notifications now inform Plus users about their remaining Deep Research reports and GPT-4.5 chats.

Users can hover over the Deep Research button to check how many reports they have left and when their limits reset, a feature also available to Pro users.

ChatGPT now provides visibility into the limitations of Deep Research and GPT-4.5 features, improving the overall experience for premium subscribers.
