Oberon and Kyber Updates, Larger World Sizes Introduced, More Networking Updates

Evidence

Nvidia provided a long-awaited update on its Kyber rack form factor, the latest addition to the lineup after Oberon having first been previewed as a prototype at GTC 2025. As a prototype, the rack architecture has continued to evolve, and we notice some changes. First, each compute blade has densified, with 4x Rubin Ultra GPU and 2x Vera each. There are a total of 2 canisters of 18 compute blades which amounts to 36 compute blades total for 144 GPUs in a rack. The initial Kyber design featured 2 GPUs and 2 Vera CPUs in one compute blade, with a total of 4 canisters of 18 compute blades each.

Context After

The details below are based on the Rubin Kyber prototypes, but Rubin Ultra will be redone.

② Atomic Claim

最初的 Kyber design，在每個 compute blade 中配置 2 顆 Vera CPU。

• Epistemic Mode: ASSERTED
• Mapping Status: COMPLETE

③ Semantic Frame

{
  "attribute": "INITIAL_COMPUTE_BLADE_VERA_CPU_COUNT",
  "context_nodes": [
    {
      "id": "04_knowledge_base/NVIDIA Vera CPU",
      "label": "Vera CPU"
    }
  ],
  "entity": {
    "id": "04_knowledge_base/NVIDIA Kyber Rack",
    "label": "Kyber"
  },
  "frame_type": "ATTRIBUTE",
  "qualifiers": {
    "condition_text": null,
    "numeric_mentions": [
      "2"
    ],
    "temporal_mentions": []
  },
  "value": {
    "numeric_mentions": [
      "2"
    ],
    "value_text": "2 Vera CPUs"
  }
}

④ Canonical Entity Mapping

Role	Surface Label	Canonical Target
entity	Kyber	04_knowledge_base/NVIDIA Kyber Rack
context_0	Vera CPU	04_knowledge_base/NVIDIA Vera CPU

⑤ V2 Draft（需要修正時直接編輯）

Inline repair

只編輯以下三個 Draft 區塊。完成後將 review_action 設為 REQUEST_REPAIR，再手動執行 Repair Preview。
執行腳本前，Draft 不會寫入 Claim Store 或 Graph。

⑥ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
• 最後選擇 review_action
