A few days after OpenAI unveiled GPT-5, its fastest and most capable AI model to date, several users asked the company to bring back GPT-4o, with many paid users even cancelling their ChatGPT subscription.
Following this, OpenAI CEO Sam Altman said that they will be bringing a wide range of upgrades to the AI chatbot. Now, in a post on X, Altman has announced that ChatGPT users can now choose between “Auto”, “Fast” and “Thinking” options when using GPT-5.
Altman went on to say that the Auto mode will suffice for most users, but the other options might come in handy for people who want more control over ChatGPT’s responses.
Apart from the new mode selection options, OpenAI has also increased the rate limits to 3,000 messages per week with GPT-5 Thinking, which has a context limit of 196,000 tokens. If you happen to exhaust it, ChatGPT will use GPT-5 Thinking mini. The AI startup also said that they might change the rate limit depending on usage.
Sam Altman also talked about GPT-5’s ‘cold’ personality, saying that the new model “should feel warmer than the current personality but not as annoying (to most users) as GPT-4o.”
And while ChatGPT Plus, Pro, Teams and Enterprise users now have the option to switch back to GPT-4o, it looks like the company won’t be making the feature available for those on the free tier.
