This issue: OpenAI's new AI just found 20,000+ vulnerabilities in open-source code. ChatGPT lost its majority market share for the first time. And your next doctor's appointment might be booked by an AI agent working for your insurer.

OpenAI Releases GPT-5.5-Cyber to Speed Up Vulnerability Patching

OpenAI says GPT-5.5-Cyber is its strongest model yet for authorized cybersecurity work, with better performance on finding vulnerabilities, tracing attack paths, validating issues, and helping defenders generate patches instead of just producing more security alerts.

Highlights

  • GPT-5.5-Cyber scored 85.6% on CyberGym

  • Codex Security scanned 30M+ commits across 30,000+ codebases

  • 500,000+ findings have already been automatically marked fixed

  • OpenAI launched Patch the Planet with Trail of Bits, HackerOne, and maintainers

  • 30+ open-source projects have committed to participate, including cURL, Go, Python, and Sigstore

Why it matters: Cybersecurity AI is moving from “find the bug” to “land the fix.” The big shift is not just that AI can discover vulnerabilities faster — it is being built into workflows that validate risk, generate patches, and help defenders close security gaps before attackers can exploit them.

America’s Biggest Health Insurer Just Put AI on the Phone

UnitedHealth is using AI to read medical charts aloud for nurses, analyze millions of customer calls, and even call doctors’ offices to schedule appointments for patients. The company plans to invest $3 billion in AI across 2026 and 2027 — and says it is already seeing a 2-to-1 return.

The latest AIHealthTech Insider also covers who gets blamed when AI misdiagnoses a patient, Samsung turning Galaxy Watch into an AI health coach, AI’s role in pancreatic cancer, and GLP-1 drugs entering the fertility conversation — all circling one uncomfortable question: when AI starts running healthcare workflows, who is watching the system?

Alibaba Cloud launched HappyHorse 1.1 on Model Studio, giving developers and enterprise teams API access to its production-ready video synthesis system.

🔹Google Just Made Gemini’s Agent API the Default

Google’s Interactions API is now generally available and becomes the main way developers build with Gemini models and agents. One call can run a model, launch an agent, use tools, browse, execute code, or keep long tasks running in the background. The signal is clear: Gemini is moving from prompt-response APIs to agent-first development infrastructure.

Sakana AI Is Hiding a Team of Agents Behind One API

Sakana AI launched Fugu, a new system that looks like a single model API from the outside — but underneath, multiple agents are coordinating the work. Developers call one endpoint, while the orchestration layer quietly decides how the agents should collaborate.

The bigger shift is the positioning. Sakana says Fugu Ultra reaches the performance tier of Anthropic’s Fable and Mythos, but through a different architecture and supply chain. That matters because Fugu is being framed as “frontier capability without the risk of export controls” — a Tokyo-built alternative for teams that want top-tier AI performance without relying on the usual frontier model pipeline.
