Summary
At FMS2026, experts pointed out that the bottleneck in AI performance has shifted from compute to data movement, especially the explosive growth of KV cache. As large models' context lengths increase, KV cache consumes significant memory and bandwidth, becoming a key factor limiting inference speed and cost.
Bubble analysis
This news discusses AI technical bottlenecks and does not directly involve investment or capital expenditure, so it is weakly related to the bubble question. However, it may influence future AI infrastructure investment direction, making it indirectly relevant.
