Three wedge themes stand out this week. First, on-device AI inference is moving fast, with multiple projects running large models on iPhones and low-RAM Macs, opening a wedge for privacy-first or offline-first AI tooling aimed at developers and prosumers. Second, agent infrastructure is fragmenting into specialized layers, from session managers and terminal UIs to channel SDKs and MCP observability, suggesting that "agent DevOps for X" is still wide open in most verticals. Third, niche filtering and curation tools (AI-free HN views, text-only microblogging, SOC 2 methodology for AI) signal growing demand for opinionated, stripped-down alternatives to bloated platforms, a classic wedge pattern worth studying.
