AI Daily Brief — 19 November 2025

Wednesday packed Ignite Day 2 plus EU + US policy. European Commission published the Digital Omnibus on AI — defers high-risk AI system rules from Aug 2, 2026 to Dec 2, 2027 (standalone) and Aug 2, 2028 (embedded in products). Aims to cut admin burden 25% (35% SMEs) by 2029 + post-market monitoring flexibility + SME simplifications. Draft Trump executive order challenging state AI laws leaked — federal-vs-state preemption debate kickoff that would culminate in Dec 11 “Ensuring a National Policy Framework for AI” order. Microsoft Ignite Day 2: Work IQ — intelligence layer letting M365 Copilot learn user, role, company — plus Word/Excel/PPT chat agents. Microsoft 365 Copilot for Business price cut $30 → $21/user/month for any M365 Business plan. Azure HorizonDB unveiled — PostgreSQL-compatible cloud-native DB separating compute + storage, scales to 3,072 vCores + 128 TB, 3× Postgres throughput, built-in azure_ai extension auto-provisions Foundry embeddings/rerankers for RAG. Private preview in 4 regions. Foundry Agent Service wires into M365 + Agent 365 (public preview) — one-click publishing to Copilot/Teams Chat; new Foundry Control Plane extends Agent 365 with observability + guardrails + lifecycle tools. xAI shipped Grok 4.1 Fast — best tool-calling model with 2M-token context + Agent Tools API providing X-search + web browsing + code execution + file retrieval + MCP integration on xAI infra. Free 2 weeks; $0.20/$0.50 per Mtoken + $5/1K tool invocations. Grok 4.1 (base) rolled out free to all users on grok.com + X + mobile — default model; improved accuracy/latency/instruction adherence/EQ/lower hallucination vs Grok 4 (64.78% blind preference in 2-week silent rollout). Gemini 3 enters general rollout across Search + app + devtools + enterprise — pitched “best model in the world” for multimodal + agentic + vibe-coding. SC25 Day 4 UALink + Ultra Ethernet BoF on open AI networking — open alternative to NVLink for accelerator-cluster scale-out.
