1. Sam Altman issues “code red” due to increased competition: OpenAI’s CEO reportedly sent a company-wide memo calling for urgent improvements to ChatGPT. The company will likely delay initiatives like ads, shopping agents, and Pulse to focus on making ChatGPT faster, more reliable, and more personable. The reason? Daily active users have declined significantly since Google launched its latest Gemini models.
2. Amazon reveals new in-house chips and frontier models: At its AWS re:Invent 2025 conference, Amazon released Trainium3, a custom AI chip that claims to cut training and operating costs by up to 50% compared to Nvidia’s chips. Amazon also unveiled four new frontier Nova models, plus a service that lets cloud clients customize their own generative AI models. View the latest updates from re:Invent here.
3. Mistral AI launches new best-in-class small models: Mistral AI unveiled a new family of small AI models designed as more adaptable alternatives to larger models. The company’s betting that the next wave of AI will be defined by models small enough to run on small devices, like cell phones. Mistral also released Mistral Large 3, a high-performing open-source frontier model. See the models in action here.
