OpenAI just rolled out Lockdown Mode to personal and self-serve ChatGPT Business accounts to fight prompt-injection attacks. Turning it on restricts live web browsing, Agent Mode, Deep Research, and file downloads, trading connectivity for airtight data security. The company is also rolling out "Elevated Risk" warning labels across ChatGPT, Atlas, and Codex.
OpenAI just rolled out a major security update to ChatGPT Atlas's browser agent, powered by an RL-trained automated red team. The internal attacker proactively hunts for complex, long-horizon prompt injection exploits before bad actors find them in the wild, baking defensive updates directly into the model checkpoint. Why it matters: as agents get the keys to your inbox and accounts, staying ahead of prompt injections is the only way to keep them safe.
OpenAI just updated its Model Spec with Under-18 Principles, setting strict boundaries for how ChatGPT interacts with 13-to-17-year-olds. The rules crack down on romantic roleplay and self-harm topics while pushing real-world support, backed by an age prediction model that defaults unverified accounts to teen mode. It is a critical move to build guardrails before regulators force their hand.
OpenAI is shutting down ChatGPT on WhatsApp on January 15, 2026, citing platform policy changes. Users who message 1-800-ChatGPT need to link their accounts through its profile link before that deadline to transfer conversation history to official ChatGPT apps, as chats won't export automatically.
OpenAI just launched ChatGPT Atlas, a brand-new web browser built around its AI assistant. Atlas features browser memories to recall context across sites you visit, alongside an agent mode that can autonomously click tabs, compare research, and book items directly on web pages. It is rolling out globally on macOS first, with Windows and mobile versions on the roadmap.
