AI Daily Brief — 15 November 2025

Saturday closed a structural week. No frontier-lab releases — but the calm-before-the-storm before “the most consequential week in AI history”: Grok 4.1 (Nov 17), Gemini 3 (Nov 18), Claude Opus 4.5 (Nov 24). $3.7B AI funding week ending Nov 15 with 96% concentrated in five deals: Anysphere/Cursor $2.3B at $29.3B + CHAOS Industries $510M + d-Matrix $275M at $2B + Gopuff $250M + Alembic $145M. World Labs Marble (Fei-Fei Li, Nov 12) shipped to GA — first commercial world model: text/photos/video/3D-layouts → 3D environments; exports Gaussian splats, meshes, videos; Chisel hybrid 3D editor. Reframed spatial intelligence as viable commercial category. Google DeepMind SIMA 2 (Nov 13 research preview) doubled SIMA 1 task completion (62% vs 31%) across virtual 3D environments — Gemini + self-improvement. d-Matrix $275M Series C at $2B (BullhoundCapital + Triatomic + Temasek with new QIA + EDBI + Microsoft M12 follow-on) for Corsair in-memory inference + JetStream networking + Aviator software stack. arXiv tightened CS submission rules (Nov 3 announce, still active discussion) — stopped accepting CS reviews + position papers because LLM-generated submissions had become “little more than annotated bibliographies.” EU “Digital Omnibus on AI” simplification being finalized for Wed Nov 19 publication: align high-risk AI with available standards, extend SME easements, remove mandatory harmonized post-market monitoring plans.

Who shipped

Nobody Saturday. OpenAI, Anthropic, Google, Meta, xAI, DeepSeek, Alibaba all dark.

Open-source pulse

No new Chinese drops. Kimi K2 Thinking + Qwen + DeepSeek continue community dominance.

Money, infra & hardware

$3.7B weekly fund + d-Matrix Corsair stack reshaping inference economics. 96% capital concentration in 5 winners signals AI VC’s late-cycle dispersion-of-mediocrity pattern.

Quiet corners

arXiv tightening + EU Digital Omnibus are the substantive structural moments behind the Saturday quiet.

  • $3.7B / 96% — weekly AI funding / share in 5 deals
  • 3 — major model launches due in 10 days (Grok 4.1 / Gemini 3 / Opus 4.5)
  • 62% vs 31% — SIMA 2 vs SIMA 1 task completion
  • $275M / $2B — d-Matrix Series C / post-money
  • Most-mentioned company: Anysphere/Cursor
  • Quietest segment: frontier-lab launches
