Panoramica dell'architettura
Attention
attention grouped-query (GQA) — 64 q-heads / 4 kv-heads. RoPE θ=5,000,000.
FFN / MoE
È un mixture-of-experts sparso con 128 esperti instradati e routing top-4; circa 25.5 milioni di parametri sono attivi per token.
La configurazione include 1 strati extra di predizione multi-token (MTP) usati per accelerare il decodice.
Confronto campo per campo
