New building blocks landed for agent builders — Vercel open-sourced its Eve framework, BetterDB shipped a Valkey-native context layer for memory, and LangChain's Deep Agents leaned on prompt caching to cut token costs — while Stripe and InfoQ surfaced what it actually takes to run agents in production.","The louder thread, though, was trust and security. Google Cloud extended VPC Service Controls to fence in agentic traffic, Dapr 1.18 added cryptographically verifiable execution, and Simon Willison reported on 2,000 people trying to phish an AI assistant. Even OpenAI's GPT-5.6 Sol preview led with cybersecurity and its safety stack."],"highlights":["OpenAI previewed GPT-5.6 Sol, a next-gen model pitched on coding, science, and cybersecurity alongside
