The analysis

Claude
Roman Kopylov by KO/TKO, 62% confidence

Kopylov's superior form (4-1 with 2 KOs) contrasts sharply with Costa's 1-4 slide. Despite Costa's volume edge (6.22 vs 4.33 SLPM), Kopylov's better defense (58% vs 49%), superior takedown defense (87% vs 80%), and southpaw stance advantage are decisive. Costa's -0.34 strike differential and poor recent durability make him vulnerable to Kopylov's power.

GPT
Paulo Costa by KO/TKO, 66% confidence

Costa brings superior power, higher striking volume, and a proven record against elite competition. While Kopylov is defensively sound and mixes in takedowns more often, Costa's pressure, physicality, and finishing ability are likely to overwhelm Kopylov in extended exchanges. Kopylov's takedown game is unlikely to be a major factor given Costa's stout 80% takedown defense.
