Anthropic open-sources its vuln-discovery harness; Apple admits its first AI agent
Anthropic open-sourced its defending-code-reference-harness for AI-powered vulnerability discovery — the most concrete first-party release of frontier-lab security tooling to date (443 HN points). Apple quietly approved Poke as the first AI agent on its Messages for Business platform, the first real third-party agent surface inside Apple's commerce stack ahead of WWDC. The AI-IPO race kept warming: Daniela Amodei pushed back on doubts about returns ahead of Anthropic's listing, and Wired documented investors backing both Anthropic and OpenAI rather than picking sides. Compute and physical-infra constraints sharpened — TSMC said it can only support so much demand, Meta started literally pitching tents over data centers to cut cost, and Kevin O'Leary halved his planned 40,000-acre Utah build under local pressure. The research wave centered on planning and values: AdaPlanBench tests agents under progressively revealed constraints, RobotValues asks whether household robots make good choices when human values conflict, and Meta-Cognitive Memory Policy Optimization sharpens the credit-assignment problem for long-horizon agents.
