Exllamav2

exllamav2 este un motor de inferență și framework de înaltă performanță pentru executarea modelelor de limbaj mari local pe GPU-uri de clasă consumer. Oferă un sistem complet pentru deployment-ul local al modelelor, incluzând un motor de inferență specializat și instrumente pentru cuantizarea modelelor.

Proiectul dispune de un framework de inferență multi-GPU care distribuie sarcinile de lucru pe mai multe plăci grafice pentru a rula modele care depășesc capacitatea de memorie a unui singur dispozitiv. Include un cuantizator de modele GPU capabil să convertească modelele în formate de precizie mixtă între 2 și 8 biți pentru a echilibra utilizarea memoriei și acuratețea.

Motorul suportă generarea de text cu throughput ridicat prin inferență paralelă bazată pe batch-uri și streaming asincron de output. Aceste capabilități sunt susținute de kernel-uri CUDA personalizate și deduplicarea cache-ului pentru a optimiza utilizarea hardware-ului și a reduce latența în timpul generării de token-uri.
