Erinevalt mullu oktoobris v\u00e4lja antud radikaalselt uuest Lyra 1.2 versioonist, mis viidi uuele n\u00e4rviv\u00f5rgu arhitektuurile, on versioonis 1.3 optimeeritud masin\u00f5ppemudelit ilma arhitektuurilisi muudatusi tegemata. Uues versioonis kasutatakse kaalude ja aritmeetiliste operatsioonide tegemiseks asemel 32-bitiseid ujukoma arve 8-bitiseid t\u00e4isarve, mis viis mudeli suuruse v\u00e4henemisele 43% ja mudeliga t\u00f6\u00f6tamise kiirus t\u00f5usis 20% v\u00f5rreldes Pixel 6 Pro nutitelefoniga testimisel.
