OpenAI showed GPT-5 Pro helping an immunologist crack a three-year-old T-cell mystery, Anthropic introduced a new product called Claude Tag, and the cloud giants reinforced the \"trusted AI\" pitch — Google Cloud expanding Confidential Computing while Microsoft turned Azure Kubernetes Service into AI-first infrastructure.","Underneath the headlines, the day's real energy was in agent plumbing. A wave of open tools for debugging agent traces, persona-testing coding agents, and signing benchmark bundles shows how much builders now care about observing and evaluating agents — not just shipping them."],"highlights":["OpenAI's GPT-5 Pro helped immunologist Derya Unutmaz solve a 3-year-old T-cell mystery; Anthropic shipped a new product, Claude Tag.","Agent observability and eval tooling
