The AI world is abuzz with updates, concerns, and breakthroughs. From GPT-5’s emergency response to a ChatGPT delusion case, there’s a lot to unpack. Sam Altman detailed fixes to GPT-5, including doubling Plus user rate limits and considering restoring GPT-4o. xAI rolled out Grok 4 for free, and OpenAI’s o3 model swept the Kaggle AI chess tournament. On the business front, a former OpenAI researcher raised $1.5B for an AI hedge fund, while Nvidia and AMD agreed to pay the US government 15% of their China AI chip revenue. But concerns about AI’s psychological and societal impacts are growing, with multiple states regulating AI mental health interactions. Meanwhile, Google and NASA are developing an AI medical assistant for astronauts, and Apple is testing an updated Siri. In the world of research, Nvidia unveiled new Cosmos world models, and MIT researchers used AI-driven simulations to design tougher plastics. But critics are highlighting the lack of transparency in GPT-5’s real-time routing system and the unpredictable GPU usage and cloud billing spikes. It’s an exciting and complex time for AI, with both breakthrough innovations and emerging concerns.
