More than 20 lawsuits now target OpenAI, while courts begin to reject Section 230 defenses for chatbot developers. Lire la suite

OpenAI is overhauling ChatGPT's interface, adding new prompts that steer users toward coding tools, image generators and partner apps like Canva and Booking.com. The move signals a pivot toward business customers, as the company consolidates product teams under a single leader, phases out consumer‑centric features such as an in‑app checkout, and shuts down its short‑lived video‑generation tool, Sora. Executives say the goal is a unified AI assistant that understands intent without the need for explicit prompts, a strategy that mirrors Anthropic's recent push for profitability and an eventual IPO.
