Ian Buck, Nvidia's vice president of hyperscale and high-performance computing, presented the announcements. Visionbay\nalso showed plans for \"K-1\", a data-center design built around Nvidia's 800-volt DC power architecture.\n\n## Why it matters\n\nGigawatt-scale sites need suppliers of racks, power gear and cooling to build to one target. Open rack and facility specifications let\nmanufacturers start before each customer issues its own design. The grid specification answers a concern of utilities: very large AI\nloads that disconnect suddenly during a fault can destabilise the grid. The same day Microsoft detailed its own 167 kW Maia 300 rack,\nwhich shows the power density these standards are written for.","disputed":[],"related":[{"id":"2026-10-12-microsoft-maia-300","url":"https://postcutoff.com/e/2026-10-12-microsoft-maia-300/","date":"2026-10-12","date_precision":"day","short_title":"Microsoft announces Maia 300, its third in-house AI chip, and plans multi-gigawatt Maia deployments from 2027","deck":null,"takeaway":"Microsoft is the largest buyer of Nvidia GPUs among cloud companies, and it now states that its own chip will be its main inference system from 2027.","category":"hardware-compute","category_label":"Chips & compute","importance":3,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":4,"official":2,"filed":"2026-10-12","updated":"2026-10-12","orgs":["Microsoft"]}],"people":[],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-10-12","type":"filed","text":"Created (evening; found through the Cisco–Nvidia USFP headline)"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-12","run":null,"sources_read":null,"updated":"2026-10-12","human_review":null,"version":null},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":165,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":104,"in_training_data":false},{"model_id":"gemini-3-8-flash","name":"Gemini 3.8 Flash","cutoff":"2026-03","days_after":195,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":134,"in_training_data":false}],"short_url":null}
