Baidu Unveils Tianchi 1,024-Card Supernode, Plans Market Launch Next Year

According to ChainCatcher, Baidu unveiled its Tianchi 1,024-card supernode at the Baidu World 2026 conference on Nov. 12, bringing its planned market launch forward by a year from 2028 to next year. Using optical-engine technology for all-optical interconnection, the system supports collaboration across 1,024 cards. Inter-card bandwidth is three times that of the previous generation, while training and inference performance are 2.5 times and three times higher, respectively. The accompanying G3.5 KV Cache memory acceleration cabinet doubles long-context inference performance, cuts first-token wait time by 90% in multi-turn conversations, and increases overall throughput sevenfold. A single supernode can support training models with 5 trillion parameters, and the system can scale to clusters of up to 500,000 cards. Baidu founder Li Yanhong also said the flagship Kunlunxin M300 will launch next year.
