OpenAI has implemented significant changes to its ChatGPT platform, making GPT-4o the default option for all paying users without the need to toggle settings. This move simplifies access to the large language model (LLM) that powered ChatGPT before the recent launch of GPT-5. Additionally, paying subscribers now have access to a new "Show additional models" setting by default, restoring access to models like GPT-4.1, o3, and o4-mini – models that focus on reasoning capabilities.
The announcement of these changes was made by OpenAI CEO and co-founder, Sam Altman, on X. Altman assured users that if GPT-4o is ever removed in the future, ample notice will be given. The ChatGPT interface now offers users the ability to choose between "Auto," "Fast," and "Thinking" modes for GPT-5. Notably, the "Thinking" mode, which features a 196,000-token context window, now has a message cap of 3,000 messages per week for paying subscribers. Altman mentioned that these limits could be subject to change based on usage patterns.
Furthermore, GPT-4.5 remains exclusive to Pro users due to its high GPU cost. Altman hinted at a forthcoming personality adjustment for GPT-5, aiming for a tone that feels "warmer" than the current default but less polarizing than GPT-4o. OpenAI is exploring per-user customization as a long-term solution to address users’ emotional connections to specific models. These changes aim to address user frustration over the sudden shift to GPT-5 and the discontinuation of older LLMs, while also potentially intensifying emotional connections users have with these models.
