Software Engineering & Architecture GitHub is overhauling how it bills for Copilot: starting June 1, the platform drops its "premium request unit" model in favor of usage-based billing via GitHub AI Credits, a shift that could significantly change cost profiles for heavy agentic users. The Copilot coding agent also now runs code scanning, secret scanning, and dependency vulnerability checks inside its own workflow before opening a pull request — reducing the review burden on engineers while raising the quality bar for AI-generated patches.

Global Macro & Markets The Fed held rates at 3.5–3.75% for a third straight meeting in late April, but the 8-4 dissent was striking — the first time four officials have voted against a FOMC decision since October 1992, with dissenters split between wanting a cut and objecting to language implying future cuts. Markets are now pricing in no rate changes through year-end, with eyes on the April CPI print due May 12 and the looming question of who replaces Jerome Powell when his term expires May 15.

Enterprise AI & AI Strategy Sierra, the AI customer-agent startup co-founded by Bret Taylor, raised $950M at a $15.8B valuation led by Tiger Global and GV — a signal that enterprise AI agent infrastructure is now attracting late-stage capital at scale. The company has grown from $100M to $150M ARR in just a few months and already serves more than 40% of the Fortune 50, making it one of the clearest proof points that AI agents are moving from pilot to production in large enterprises.

AI Tools & Developer Utilities A new MCP server called n8n-mcp (released May 5) lets Claude, Cursor, and Windsurf users build n8n automation workflows entirely through natural language, exposing all 1,650 of n8n's nodes — including 830 community nodes — to AI assistants without requiring drag-and-drop interaction. It's a practical demonstration of MCP's compounding effect: as more tools expose structured interfaces to AI agents, the gap between "describing what you want" and "having it built" continues to shrink.
