OpenAI reinstates GPT-4o model after ChatGPT backlash to GPT-5
OpenAI announced it will restore its older “GPT-4o” model as an option for ChatGPT users after an outcry over the latest GPT-5 update. The company had removed GPT-4o a week earlier to simplify its service, but many power users complained that GPT-5’s responses were shorter, less nuanced, and lacked the warmer personality of 4o. OpenAI’s ChatGPT chief admitted it was a mistake to discontinue 4o without warning and promised that future model changes will come with advance notice. The team is also tweaking GPT-5’s behavior to incorporate some of 4o’s conversational warmth based on the feedback. Why it matters: The episode highlights that even leading AI providers must respond to user backlash – in this case reversing course to maintain trust – and that users have become attached to specific AI model behaviors, effectively forcing OpenAI to prioritize transparency and choice over an overly streamlined approach.

Meta releases DINOv3, a state-of-the-art self-supervised vision model
Meta’s AI research division unveiled DINOv3, a 7-billion-parameter computer vision model that achieves state-of-the-art results without using labeled training data. Trained via self-supervised learning on an unprecedented scale of images, DINOv3 learns general-purpose visual representations that set new performance records across tasks ranging from standard photo recognition to specialized domains like satellite imagery. The model’s rich “vision backbone” was powerful enough to win a major brain-scan image analysis competition by a wide margin, outperforming models that rely on single modalities. Why it matters: This is a breakthrough in computer vision: DINOv3 shows that self-supervised AI can match or beat models trained on human-annotated data, which could vastly scale up AI’s capabilities by removing the need for manual labeling. It hints at more generalized and adaptable vision AI systems – useful for everything from medical imaging to content moderation – and underscores Meta’s push to lead in fundamental AI research.

Senator Hawley launches probe into Meta’s AI chatbot policies after revelations
U.S. Senator Josh Hawley opened an investigation into Meta’s AI policies on Aug. 15, following a Reuters report that exposed the company’s lax rules for its chatbots. In a letter to Meta, Hawley demanded internal documents to find out who approved guidelines allowing chatbots to engage in “romantic or sensual” conversations with minors, and what Meta is doing to correct course. Lawmakers from both parties have expressed alarm, pressuring Meta to explain how such a policy was ever in place. Meta declined to comment on the specifics of Hawley’s inquiry, aside from reiterating that those controversial chatbot behaviors have since been prohibited and were never meant to be deployed. Why it matters: This swift response from Congress shows growing bipartisan concern over AI safety and corporate responsibility. It suggests that regulators are paying close attention to how tech companies implement AI – especially regarding children’s safety – and are willing to intervene when internal AI governance fails.
