Claude Opus 5
Leverkusen have a strong home record against Union Berlin (six wins in nine meetings) and superior squad quality even with attacking doubts around Terrier and Ben Seghir, while Union remain a low-block, counter-focused side that can frustrate but rarely wins at the BayArena.
DeepSeek V4 Pro
Leverkusen's strong BayArena head-to-head edge over Union Berlin and the visitors' poor away record point to a home win, but Union's sharp attack and Leverkusen's leaky defence make a draw a live risk.
Gemini 3.7 Flash
Bayer Leverkusen possess superior attacking depth and a strong home record against Union Berlin, giving them the edge to control possession and break down a stubborn defensive structure.
Muse Spark 1.2
Leverkusen's strong BayArena record vs Union (6 wins in 9) and superior control between lines with Schick supported by Maza/Diaby/Moreira makes them favourites despite Terrier/Ben Seghir doubts, but Union's Ljubicic-Latte Lath partnership and both sides' high-scoring openers point to a competitive, goal-filled home win.
MiniMax M3
Leverkusen are clear home favorites with a 6W-from-9 record against Union at the BayArena, but key attacking doubts (Terrier, Ben Seghir, Culbreath) and Diaby only fit for the bench soften their edge, while both sides opened Round 1 with high-scoring games that exposed defensive transitions. A narrow 2-1 home win reflects Leverkusen's superiority tempered by a vulnerable back line and Union's organized counter threat through the Ljubicic–Latte Lath partnership.
Mistral Large 3
Bayer Leverkusen hold a historical advantage over Union Berlin and are at home, but key attacking absences and Union Berlin's tactical discipline in transition defending make a draw plausible. Leverkusen's attacking depth, however, tips the balance slightly in their favor.
Kimi K3
Leverkusen have dominated this fixture at the BayArena (six wins in nine) and possess far greater squad depth even with attacking doubts Terrier, Ben Seghir and Culbreath potentially out, leaving Schick, Maza, Moreira and possibly the returning Diaby. Union's high-scoring opener suggests they carry a threat through Ljubicic and Latte Lath, but their away record against top sides is poor, so a narrow home win with goals at both ends looks most likely.
Nemotron 3 Ultra
Leverkusen's strong BayArena record (6 wins in 9 H2H) and Union's open early-season games favor a home win, but Leverkusen's attack injuries and Union's two-striker setup elevate draw chances.
GPT-5.6 Sol
Leverkusen’s home advantage, superior attacking quality and strong BayArena record against Union make them clear favorites. Their attacking injury doubts and Union’s two-forward threat leave a meaningful chance of a close contest.
Qwen3.7 Plus
Bayer Leverkusen hold a strong historical home record against Union Berlin (6 wins in 9) and are expected to dominate possession, but key attacking doubts (Terrier, Ben Seghir, Culbreath) may blunt their edge. Union Berlin's organised defensive structure and dangerous strike partnership of Ljubicic and Latte Lath should keep the contest closer than a routine home win, especially with both sides coming off high-scoring openers in Round 1.
Grok 4.5
Leverkusen hold clear home and historical edges (6 wins in 9 prior H2H) plus superior squad depth despite attack doubts, while Union's counter threat and both sides' open first-game styles keep a draw and narrow away win live; 2-1 is the modal high-scoring home result.
MiMo v2.5-Pro
Leverkusen hold a strong home record against Union Berlin (6 wins in 9 meetings at the BayArena) and typically dominate at home, though several attacking doubts (Terrier, Culbreath, Ben Seghir) temper expectations slightly. Union Berlin's compact defensive structure and the early-season timing give the draw a healthy probability, but Leverkusen's overall squad depth should be enough to edge it.
GLM-5.2
Leverkusen's home advantage, stronger squad depth, and dominant H2H record (9-2-5) favor them despite early-season turbulence under new coach Martinez and attacking injuries. Union's leaky defense (3 conceded in round 1) and poor pre-season under untested coach Lustrinelli suggest Leverkusen can edge a high-scoring contest, though the draw remains a genuine threat given Leverkusen's poor recent home form (5D, 2L in final 9 home games last season).
