How Claude Code Ported a 0.2B AI Image-Editing Model to Run Entirely in Your Browser
ByTejinder Singh June 23, 2026

Reading Time: 5 minutesSimon Willison used Claude Code to convert the Moebius 0.2B inpainting model from a Python-only tool into a fully browser-based app running on WebGPU — without writing a single line of code himself. The exercise reveals how Claude Code can handle model conversion, cloud deployment, and UI building autonomously, pointing toward a future where AI image tools run locally in a browser tab with no server required.

Google DeepMind’s AI Control Roadmap: Why the Next Frontier of Safety Looks Like an IT Security Manual
ByTejinder Singh June 22, 2026

Reading Time: 6 minutesGoogle DeepMind has published an AI Control Roadmap that treats powerful internal agents as insider threats, borrowing cybersecurity frameworks to layer runtime monitoring, access controls, and AI supervisors on top of model alignment. The Neuron reports that DeepMind anchors the roadmap in concrete operational metrics — coverage, recall, and time-to-response — signalling that AI safety is evolving from a research discipline into an engineering operations practice.

When AI Becomes the Doctor’s Second Opinion: OpenAI’s Reasoning Model Cracks 18 Unsolved Rare-Disease Cases
ByTejinder Singh June 19, 2026

Reading Time: 5 minutesOpenAI’s o3 reasoning model helped physicians at Boston Children’s Hospital and Harvard uncover 18 confirmed diagnoses from 376 previously unsolved rare-disease cases, according to The Neuron. The study illustrates a near-term model for medical AI as a tireless second reader that generates leads for human clinicians to validate, not a replacement for clinical judgment.

The Mythos Deadlock: Why Anthropic and the U.S. Government Can’t Find Common Ground
ByTejinder Singh June 18, 2026

Reading Time: 5 minutesAnthropic’s most capable AI model, Mythos, remains offline after a U.S. Commerce Department letter warned against distributing it to foreign persons, with a South Korean firm’s suspected China ties fueling the dispute. The standoff has deepened over government demands for complete jailbreak prevention — a condition AI safety researchers consider technically impossible to fulfil.
