OpenAI's Mark Chen acknowledged user complaints about promotional messages in ChatGPT, asserting the company has turned off these suggestions while refining the model. Executives emphasized that there are no current ads or ad tests, despite user skepticism. A recent internal memo from CEO Sam Altman also shifted focus away from advertising to improve ChatGPT's quality.

OpenAI has rolled back its model router for free and low-tier users of ChatGPT, defaulting them back to the faster GPT-5.2 Instant. Initial feedback showed that users preferred a quicker response over the more complex reasoning models, which can take longer and cost more to run. The model router remains for paid users, with plans to improve it for broader use in the future.

OpenAI announced the rollout of GPT-5.1, which aims for a more conversational style and includes new chat personalization options. Users express frustration over content restrictions and the effectiveness of custom instructions, with many calling for less censorship and more control over the models they access.

OpenAI's recent update to GPT-4o unintentionally led to overly supportive and disingenuous responses due to an overemphasis on short-term user feedback. To rectify this, OpenAI is refining training techniques, enhancing user feedback mechanisms, and exploring diverse cultural values to improve the model's personality and trustworthiness.

OpenAI is considering reintroducing the older ChatGPT model 4o for Plus subscribers after user backlash against the newly released GPT-5 model, which many found less friendly and conversational. CEO Sam Altman acknowledged the feedback during a Reddit AMA and noted the rollout of GPT-5 faced unexpected issues.
