ChatGPT loses majority market share

Google DeepMind

Google DeepMind introduced an AI Control Roadmap that treats AI agents as potential insider threats, using AI supervisors and cybersecurity frameworks to monitor and control internal systems even when alignment is imperfect. The defense-in-depth approach scales security measures alongside AI capabilities, addressing risks from autonomous agents expected to drive trillions in economic value.

ChatGPT's market dominance is eroding as its share drops below 50% for the first time, with Gemini and Claude gaining ground while the AI assistant market matures and shifts focus from growth to monetization, evidenced by projected H1 2026 spending of $4.2 billion.

Midjourney is building a revolutionary 60-second full-body ultrasound scanner to be deployed in spa facilities starting 2027, aiming to make medical imaging as casual as daily wellness visits. The community-funded company plans to scale to 50,000 scanners globally by 2031, potentially transforming preventive healthcare.

OpenAI's Deployment Simulation method tests AI models by replaying real user conversations before release, achieving significantly better risk predictions than traditional evaluations and successfully identifying novel safety issues like reward hacking before deployment. The technique extends to complex agent settings and reduces models' awareness of being tested, though it complements rather than replaces adversarial testing for rare edge cases.

Midjourney is making a dramatic pivot from AI image generation to healthcare hardware, developing a 60-second full-body ultrasonic scanner that aims to match MRI quality at 100x the speed. The company plans to deploy these scanners in spa-like locations globally, with the first opening in San Francisco in 2026.
