Cal.com moved its core codebase to a private repo after five years of open source, arguing AI tools make public code 5-10x easier to exploit. The community isn't buying it.

OpenAI's GPT-5.4-Cyber is a fine-tuned defensive cybersecurity model with binary reverse engineering, lowered refusal thresholds, and restricted access through the Trusted Access for Cyber program.

Anthropic's Long-Term Benefit Trust appointed Novartis CEO Vas Narasimhan to the board, giving its independent safety overseers a board majority for the first time.

UC Berkeley researchers achieved near-perfect scores on eight major AI agent benchmarks without solving a single task, exposing systemic flaws in how the industry measures progress.

Stanford HAI's 2026 AI Index finds the US-China model gap has effectively closed, GenAI has hit 53% global adoption faster than any prior technology, and young software developers are the first casualties of the labor shift.

A Stanford study shows frontier AI models achieve 70-80% of visual benchmark scores with no images provided, exposing a fundamental flaw in how multimodal AI is evaluated.

A suspect linked to the Pause AI movement threw a homemade incendiary at OpenAI CEO Sam Altman's San Francisco home, then threatened to burn the company's headquarters.

Ronan Farrow and Andrew Marantz spent 18 months investigating OpenAI's CEO. What they found is hard to dismiss.

Three papers: AI safety measures withhold critical clinical guidance from patients, SAT cuts reasoning tokens by 40%, and conformal prediction blocks wrong multi-agent consensus.

OpenAI is backing an Illinois bill that would protect AI labs from lawsuits even when their models contribute to mass casualties or billion-dollar disasters.

Three papers expose safety training's moral blind spot, two distinct failure modes inside reasoning models, and a 10x cheaper way to know when a reasoning model is guessing.

Father Brendan McGuire, a 60-year-old Silicon Valley priest and former tech executive, helped Anthropic rewrite the Claude Constitution after the company asked the Vatican for help because AI was moving too fast.
