KV Cache Study Native QA - BABILong: leaderboard
KV Cache Study Native QA - BABILong: Acc. over 300 examples (%). KV cache updates arXiv 2611.14051v1: native Source and Target use each checkpoint for both prefix and continuation; cross-cache Reuse/Mapper are not native model observations. Six NIAH prefix lengths each have eight histories x24 queries=192. Native unmodified GLM-5.2/5.3, DeepSeek V4.1 Flash/1017, DeepSeek V4 Flash/0731 and Qwen3-30B-A3B/Instruct-2507 remain distinct checkpoints. Free generation greedy. Table 8 is the separate 585-example BABILong/QA cohort. No base/instruct merge and no reuse accuracy attributed to native model.
Metric: Acc. over 300 examples (%). Source: arxiv.org. Saturation forecast: Around February 2027. 2 models tracked.
