We’d recommend the Fire TV Stick 4K Plus overall, but if you just want a cheap and basic 4K streaming stick — maybe one for a second or third TV — the standard Fire TV Stick 4K is hard to ignore at $20. The redesigned Fire TV OS has yet to roll out to the stick, and it has half the RAM so it’s slower. It also lacks Dolby Vision and Dolby Atmos support, but it still supports HDR10, HDR10 Plus, and Alexa Plus while including an Alexa Voice Remote. You also get access to all the major streaming services, while Xbox Game Pass Ultimate subscribers can stream select games from the cloud as they can on Amazon’s other sticks.
需要注意的是，传统的嵌入向量检索技术靠计算余弦相似度只能做到缩小范围，但无法直接实现高精度的匹配，因为依靠向量计算出来的概率进行关联匹配是不可靠的。
