VERIFIED NEGATIVE: Iluvatar's own BI-V150 (Tiangai 150) product page exists, returns HTTP 200, and contains NO specification table and no interconnect figure of any kind - not a blank field, an absent section

TESTED 2026-10-05 by web_extract on https://www.iluvatar.com/productDetails?fullCode=cpjs-yj-xlxl-tg150 - HTTP 200, 3,970 characters of markdown retrieved successfully. THE PAGE IS REACHABLE. That is the point of recording it: this is a negative established against a page we could actually read, not a page we failed to load. SUBSTRING COUNTS OVER THE ENTIRE RETRIEVED BODY, which is the evidence rather than a claim of absence: 产品规格 / 规格 (specification table heading): 0 occurrences 接口 (interfaces): 0 PCIe: 0 GB/s: 0 TB/s: 0 互联 (interconnect): 0 BI-V150 / V150 / BI (the part number itself): 0 功耗 (power): 1, 内存 (memory): 2, 带宽 (bandwidth): 1 The whole page is 产品特点 (feature bullets) plus navigation. The bullets are about software: '生态友好，支持异构方案混训', '支持包括DeepSpeed、Megatron-DeepSpeed、Megatron-LM、Colossal-AI等主流框架，提供自研的推理框架无缝兼容vLLM和TGI热门框架', '快速支持国内外新兴大模型，包括LLaMa，Qwen，Yi'. Assets are dated 20251021. NO HARDWARE SPECIFICATION SECTION EXISTS ON THIS PAGE. WHY THIS MATTERS FOR THE CONNECTINVENTORY SPECIFICALLY. The corpus has accelerator records iluvatar-bi-v150 and iluvatar-bi-v250, and BI-V150's own notes already say the BI-V100/MR-V100 pages publish memory type and capacity but no bandwidth. What was NOT established is whether the newer part publishes more. It does not: BI-V150, a part Iluvatar markets as supportable for '最新版本和最大参数量' of Llama and Qwen, publishes LESS than the generation before it. A scale-up fabric record for BI-V150 is therefore a verified negative rather than a thin record, and the distinction is the entire deliverable. THE BI-V250 IS A STRONGER NEGATIVE AND IS NOT THIS SOURCE. https://www.iluvatar.com/productDetails?fullCode=cpjs-yj-xlxl-tg200 was also tested 2026-10-05 and returned a Nuxt application error page ('An error occurred in the application and your page could not be served'), 177 characters, no product content. That is a BROKEN PAGE, which is weaker evidence than an empty one - a page that errors may still have been populated. Recorded here so a future pass does not re-spend the fetch, and deliberately NOT used as the basis for any negative claim about BI-V250. The mirrorfrog.com third-party page (cn-iluvatar-bi-v150) labels its own BI-V150 memory figures as estimates and warns 'Detailed specifications of TianGai 150 are not fully disclosed by official sources' - that aggregator comment is now confirmed to be accurate about the vendor, not merely cautious.
