OpenAI has updated GPT-5 to make its tone noticeably warmer and more engaging, without reverting to the overly flattering style some users criticised in GPT-4o. The change is rolling out, aiming to balance emotional resonance with substance.

CEO Sam Altman stated the adjustment directly responds to users finding GPT-5 too formal or robotic. The update is subtle yet visible, enhancing conversational warmth while avoiding sycophantic tendencies.

OpenAI also expands user control by offering three interaction modes, Auto, Fast, and Thinking, which adapt response style to user preference. These changes empower users to shape the tone and depth of their AI interactions.

Reacting to public frustration, OpenAI has reinstated GPT-4o (along with GPT-4.1, o3, and GPT-5 Thinking mini) for paid subscribers, while promising more customisation options in future updates.
