ChatGPT 5 gets major upgrade with 3 new response modes
On Wednesday, OpenAI CEO Sam Altman unveiled a series of updates to ChatGPT. These updates give users more control over the company’s latest GPT-5 model and expand the model options available to paid subscribers.
This was reported by Sam Altman on X.
Powerful new controls for GPT-5 users
In a post, Altman announced that users can now select one of three response modes for GPT-5: "Auto", "Fast", or "Thinking". While most users are expected to stick with Auto, these additional settings aim to help those seeking faster replies or deeper reasoning.
The weekly rate limit for GPT-5 Thinking has been set at 3,000 messages. After reaching this limit, users will have access to extra capacity via GPT-5 Thinking Mini.
The model now supports a 196k-token context limit, enabling it to process much longer conversations and documents. Altman noted that these limits could change over time based on usage patterns.
GPT-4o returns
He also confirmed that GPT-4o is now available in the model picker for all paid users. There is a "Show additional models" toggle in ChatGPT's web settings that unlocks access to options like o3, 4.1, and GPT-5 Thinking Mini. However, the GPT-4.5 model remains exclusive to Pro subscribers, as Altman cited its high GPU cost.
