For anyone wiring models into agents, the developer notes — not the launch posts — are where the actionable changes live.","Underneath the releases, the day was really about operating agents in production. Elastic open-sourced a cognitive-science memory system, cheaper ways to judge agent traces and verify skills surfaced, and NVIDIA reframed inference around cost-per-token as teams move from pilots to AI factories. Security and governance for AI-assisted development matured in parallel, from Copilot Autofix on Azure DevOps to a controls crosswalk against NIST, ISO 42001, and OWASP."],"highlights":["Anthropic
