OpenAI unveiled Daybreak on May 11, 2026, a new cybersecurity service that leverages its latest AI models, including GPT‑5.5 and Codex Security, to automate vulnerability detection, patch generation and audit reporting. The initiative positions OpenAI against Anthropic’s Claude Mythos and comes with a roster of partners such as Cloudflare, Cisco, CrowdStrike, Palo Alto Networks, Oracle and Akamai.
Robinhood Markets filed a confidential registration statement to launch RVII, its second publicly traded venture fund, expanding beyond the late‑stage companies that anchor its first fund, RVI. The new vehicle will target growth‑stage and early‑stage startups, opening the private‑market upside to everyday investors without accreditation requirements. RVI, which debuted at $21 per share and now trades above $43, has already doubled in value, driven by optimism around AI‑heavy holdings such as OpenAI and Databricks. CEO Vlad Tenev says the move aims to let retail investors sit at the ground floor of future tech breakthroughs.
OpenAI unveiled Daybreak, a new AI‑driven security platform that combines its latest GPT‑5.5‑Cyber models with the Codex Security agent. Designed to map an organization’s code, predict attack paths and auto‑detect high‑risk flaws, Daybreak aims to stay a step ahead of cyber attackers. The rollout follows Anthropic’s controversial Claude Mythos release and marks OpenAI’s first foray into dedicated vulnerability‑prevention tooling, with the company pledging collaboration with industry and government partners as the service scales.
Google’s Threat Intelligence Group disclosed that a criminal hacking crew used an artificial‑intelligence model to locate a zero‑day flaw in a widely used open‑source system‑administration platform. The vulnerability could have bypassed two‑factor authentication and enabled a mass exploit across multiple organizations. Google intervened, alerted the software’s developers, and helped roll out a patch before the attack could be launched. The report, which does not identify the attackers, the software, or the AI model, also notes growing interest from state‑linked groups in AI‑assisted hacking tools.
Thinking Machines, the artificial‑intelligence startup founded by former OpenAI CTO Mira Murati, announced Monday that it is developing "interaction models"—systems that process audio, video and text simultaneously and respond in real time. The company says current AI models operate in a single‑threaded fashion, creating a bottleneck that limits natural human‑AI collaboration. Murati’s team showcased the new tech with demos ranging from live animal‑mention detection to real‑time speech translation and posture alerts. A limited research preview is slated for the coming months, with a broader release expected later this year.
OpenAI has begun rolling out a new Trusted Contact tool for ChatGPT that lets users name a trusted adult who can be notified if the AI detects signs of self‑harm. The system flags at‑risk conversations, warns the user, and then passes the case to a human review team before any alert is sent. Notifications are delivered by email, text or in‑app message without sharing chat transcripts. Developed with input from mental‑health experts and a network of more than 260 doctors, the feature adds to OpenAI’s existing safety controls and raises questions about AI‑driven monitoring.
