Inside KV-Cache Sharing: How DeepSeek CED and GLM 5.2 Differ
Developers break down KV-cache sharing designs: YOCO lets all layers in the model's second half share one KV cache; DeepSeek's CED applies a similar YOCO-style global branch per CSA2 layer, caching only encoder KV; GLM 5.2 scores per token while sharing block indices for flexibility and performance.
