Imibuzo ehlobene ye-repository ingabe iselule ingxoxo iye ekuqedweni kwama-loop, ekugunyazweni ngumuntu, ezenzweni ezihlehlisekayo, ekulandekeni kwamarekhodi, kanye ne-drift phakathi kwemisebenzi ethatha isikhathi eside.

Amathiphu Athuthukile Okulungiselela

Zilolonge Ngokuthola Izibalo, Hhayi Izincazelo Kuphela

Imibuzo eminingana icela amafomula noma izilinganiso zezinombolo. Zilolonge ukubala inkumbulo ye-KV-cache, inkumbulo yama-model weight kuma-precision ahlukene, inkumbulo ye-fine-tuning, kanye nomthamo olinganiselwayo we-serving. Yisho okucatshangwayo ngaphambi kokubala ngoba imiphumela incike ku-architecture, precision, ubukhulu be-batch, kanye nobude be-sequence.

Xhumanisa Imiqondo Ezigabeni Ezihlukene

Izimpendulo eziqinile ze-interview zivame ukuxhumanisa i-architecture nokuziphatha ekukhiqizeni. Ngokwesibonelo:

• Ukuklanywa kwe-KV-cache kuxhumanisa i-transformer attention ne-GPU memory kanye nomthamo we-serving.
• I-quantization xhumanisa i-numeric precision nekhwalithi yemodeli, ukusetshenziswa kwenkumbulo, kanye ne-throughput.
