A curated weekly roundup of five major AI/ML developments from late July to early August 2026. Moonshot AI released full weights for Kimi K3, a 2.8-trillion-parameter MoE model requiring data-center-scale infrastructure. The MCP Go SDK shipped a stateless protocol rewrite (version 2026-07-28), removing session IDs and enabling standard load balancing. Microsoft announced Project Perception, a multi-agent security system using specialist model routing to cut costs by ~50%. The EU AI Act's Article 50 transparency requirements took effect, mandating AI disclosures and machine-readable content markings. GitHub fully retired its Models service while AWS moved several first-generation AI services (Bedrock Agents, Kendra, Q Business) to maintenance mode for new customers. The overarching theme: AI systems are becoming easier to connect but harder to own, with managed services carrying lifecycle risk and open weights not equating to accessible infrastructure.
