Baidu unveils Tianchi 1024-card supernode, launching next year

On November 12, 2026, during the opening ceremony of Baidu World 2026, Shen Dou, Executive Vice President of Baidu Group, unveiled the Baidu Tianchi 1024-card supernode and announced that this compute cluster will reach the market next year.

According to Baidu, the Tianchi 1024-card supernode is built on industry-leading optical engine technology, which triples the inter-card interconnect bandwidth over the previous generation. Compared with the prior product, training performance improves by 2.5x and inference performance by 3x. A single cluster can support training of large models with 5 trillion parameters, and the architecture is designed for horizontal scaling, allowing expansion to clusters of up to 10,000 cards. The companion G3.5 KV Cache memory acceleration cabinet strengthens cache reuse, boosting long-context inference performance by 2x. In multi-turn dialogue scenarios where the cache hits, TTFT drops by 90% and overall throughput rises by 7x.

The report also notes that Baidu had previously announced at last year's Baidu World conference that the Tianchi 1000-card-class supernode would launch in 2028, so the current timeline pulls the schedule forward by one year. The release of the Kunlunxin N-series has also been moved up to 2028. At present, the Tianchi 1024-card supernode is slated for market availability next year, and further details on its rollout are still pending from the company.
