The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
周度数据同样显示出国产模型的强势表现。2 月 9 日至 15 日，中国模型调用量首次超过美国模型；16 日至 22 日，中国模型周调用量进一步升至 5.16 万亿 Token，三周累计涨幅达 127%。
