Altman and other OpenAI leaders took questions on Reddit on Friday, a day after the announcement of the new GPT-5 model. A quick glance through the comments revealed how many users preferred how older models like GPT-4.1, GPT-4.5 and 4o handled writing and other tasks. Some said the other models seemed more friendly and conversational than GPT-5.

In a major shift, the company is “open sourcing” two A.I. systems, freely sharing the technology with outside researchers and businesses.

OpenAI is providing access to its ChatGPT product to US federal agencies at a nominal cost of $1 a year as part of a push to get its AI chatbot more widely adopted.
