Microsoft flipped the switch on Azure's first GB300 NVL72 cluster: 4,600+ GPUs networked as a single accelerator. Satya Nadella calls it the "first of many." Bottom line: Microsoft can run frontier reasoning models at scale today, not next year. This is the new baseline for hyperscale AI infrastructure.
This week crystallizes where we are: Microsoft deploys 4,600 GPUs as one system. OpenAI diversifies chip suppliers while announcing 10 GW targets. AMD gets equity warrants for real delivery commitments. The infrastructure race isn't coming: it's here, at unprecedented scale and speed. Meanwhile, regulators are activating new powers across UK and EU. This is the new normal.

THIS WEEK'S SIGNAL
OpenAI Goes Custom Silicon
OpenAI partnered with Broadcom to build custom AI chips targeting 10 GW of compute by 2029. The signal: diversify beyond Nvidia/AMD to control per-token economics.
OpenAI signed a multi-year GPU supply deal with AMD and granted a warrant for up to 160M shares (performance-contingent). Translation: real volumes, material alignment, multi-vendor forever.
OpenAI's Sora 2 video app hit 1M+ downloads in <5 days. The creator-rights debate is heating up fast. Short-form, AI-native video just went mainstream.
Google launched Gemini Enterprise (chat-with-your-work-data) and embedded Gemini in Chrome for on-page help. Clear shot at Microsoft's Copilot dominance.
Apple sued over alleged use of copyrighted books to train Apple Intelligence. Courts will keep dragging model training into discovery and provenance debates.
Microsoft's 4,600-GPU cluster + OpenAI's 10 GW custom-chip plan = proof hyperscalers are pouring massive capex into AI infra, right now.
Unlikely Partnerships
Microsoft brings Anthropic to Copilot (via AWS); OpenAI diversifies to Broadcom while keeping Nvidia/AMD. Multi-vendor is standard.
Regulatory Pressure Intensifies
UK CMA designates Google Search; EU scrutinizes platforms for child safety. Compliance load accelerating across jurisdictions.
IP & Training Data Normalize
Apple lawsuit keeps provenance squarely in spotlight. Expect more licensing workflows and transparency tooling across the stack.
