AI Round-up: April 7, 2026

Anthropic dominated this snapshot. The company paired a Google-Broadcom compute pact and a reported $30 billion revenue run-rate with fresh Claude Code healthcare examples, while Reddit and YouTube stayed fixed on Claude Code's Ultraplan rollout, perceived model-quality drops, throttling complaints, and the longer tail of leak analysis.

A second strand focused on governance, security, and infrastructure. OpenAI drew attention with a New Yorker investigation into Sam Altman, an anti-competition complaint against Elon Musk, and a new Safety Fellowship, while Microsoft highlighted AI-enabled device-code phishing, Google and Broadcom reinforced the AI chip build-out, and creator coverage clustered around Karpathy-inspired knowledge bases, Copilot Cowork, and agent workflow tools.
