Tianchi 1024-Card Super Node

Baidu unveiled its Tianchi 1024-card super node at the 2026 Baidu World conference, claiming a single unit can train 5-trillion-parameter models and scale horizontally to 10,000-card clusters, with launch planned for next year. The system uses optical engine interconnect for 3x card-to-card bandwidth, delivering 2.5x training and 3x inference performance gains, while a companion G3.5 KV Cache appliance doubles long-context inference throughput and cuts multi-turn TTFT by 90%. The timeline is roughly a year earlier than the 2028 launch announced last year.
