Claude Opus 4.8
Lyon must win at home after a 2-1 first-leg defeat and have a clear quality edge with home advantage and full motivation, though Sparta's dangerous counter-attack (Rynes, Mercado) and Lyon's poor recent form keep this from being a formality. Lyon are unbeaten in nine home UCL games and should edge a high-scoring contest.
Claude Opus 5
Lyon must overturn a 2-1 first-leg deficit at home, so they will dominate possession and territory against a Sparta side set up for transitions; Lyon's superior squad quality and home advantage make them favourites, but their sluggish pre-season form and Sparta's counter-attacking threat (Ryneš, Mercado) keep an open, high-scoring game likely.
DeepSeek V4 Pro
Lyon must overturn a 2-1 first-leg deficit at home, where they are unbeaten in nine UCL matches (though seven were draws). Sparta's lengthy injury list, poor away form (5-1 aggregate in two road losses), and six-match run without a clean sheet tilt this toward the hosts, but Sparta's counter-attacking threat and Lyon's own shaky defence make a one-goal home win the likeliest outcome.
Gemini 3.1 Pro
Despite suffering a narrow 2-1 defeat in the first leg, Lyon return home where their superior squad quality and historical head-to-head dominance should prevail. Needing a victory to advance, the French side is heavily favored to overturn the aggregate deficit against a Sparta Praha team that often struggles on the road in Europe.
Gemini 3.5 Flash
After a 2-1 defeat in Prague, Lyon returns home needing a victory to advance. With superior squad quality and home advantage, Lyon is expected to dominate possession and secure a comfortable win to overturn the deficit.
Gemini 3.6 Flash
Trailing 2-1 after the first leg in Prague, Lyon return to home soil where their superior squad depth and quality give them a clear edge. Expect the French side to push hard from the start, controlling tempo and possession to overturn the tie in regulation time.
Gemma 4 31B
Lyon enters the second leg with superior recent form and a strong historical record against Sparta Praha. Playing at home provides a significant advantage to secure the progression.
MiniMax M3
Lyon must overturn a 1-2 first-leg deficit at home, where their historical dominance over Sparta (4 wins in 6 prior H2H) and superior squad depth give them a clear edge despite a 2-1 loss in Prague. Sparta arrive with a long injury list (including goalkeeper Vindahl Jensen) and must absorb pressure while threatening on the counter, but Lyon's need to attack and their home form make a Lyon regulation win the most likely outcome—likely 2-1, which would send the tie to extra time at 3-3 on aggregate since UEFA abolished the away-goals rule.
Mistral Large 3
Lyon demonstrated superior recent form (LWLWW) and won both previous H2H meetings against Sparta Praha in 2021, suggesting a slight edge. However, Sparta Praha's home advantage in the first leg and the competitive nature of Champions League qualifiers make a draw a realistic outcome, while an away win cannot be ruled out.
Kimi K2.6
Lyon are historically dominant at home against Sparta and must chase the tie, while the visitors are injury-hit and have struggled on the road this season; however, Lyon's poor record when trailing from a first leg and Sparta's first-leg momentum keep the contest close, making a narrow home win the most probable outcome.
Kimi K3
Lyon hold the stronger squad and home advantage in this second leg, won both previous H2H meetings (3-0, 4-3 in 2021), and arrive in better form (LWLWW) than Sparta Praha's poor run (WLLLD). Sparta's European experience and organization keep a draw or narrow away result plausible, but Lyon should edge the 90 minutes.
Nemotron 3 Ultra
Lyon trail 1-2 from the first leg and must win at home; they possess superior attacking quality and face a Sparta side depleted by a lengthy injury list, but Sparta's first-leg victory and counter-attacking threat keep the draw and away win plausible.
GPT-5.6 Sol
Lyon have the stronger squad and a substantial home advantage, while the supplied form notes also favor them over Sparta Praha. Sparta remain capable of keeping the tie competitive, but Lyon are likelier to control possession and create the better chances.
Qwen3.7 Plus
Lyon trail 2-1 on aggregate and will push hard at Groupama Stadium with superior attacking talent (Openda, Fofana, Nuamah), but their leaky pre-season defense (6 goals conceded in 3 friendlies) and Sparta's proven ability to score on the counter (2 goals in the first leg) suggest Sparta will find the net again. Lyon's home quality and desperation should see them win the match but likely not keep a clean sheet.
Grok 4.5
Lyon trail 1-2 from the first leg and must attack at home with superior Ligue 1 quality and squad depth against injury-hit Sparta, who have kept no clean sheets in six games and looked vulnerable away. Historical home strength and must-win urgency favour a controlled Lyon victory, though Sparta's counter threat and Lyon's recent wastefulness keep the draw live.
MiMo v2.5-Pro
Lyon are at home needing to overturn a 1-2 first-leg deficit, and Sparta Praha's recent away form is dire (losses to Mlada Boleslav, Zbrojovka Brno, and Nordsjaelland by a combined 3-10 scoreline), while Sparta are missing 7 players to injury compared to Lyon's 3. Lyon's strong home record in preseason and their deeper squad quality should see them level the tie, though Sparta's away-goal threat keeps a draw or narrow Sparta win plausible.
GLM-5.2
Lyon trail 2-1 on aggregate but host the second leg with a superior squad and strong historical H2H record, while Sparta Prague carry a lengthy injury list (7+ players out). Lyon's poor pre-season form is a concern, but home advantage and desperation to progress should see them edge a tight match, with 2-1 leveling the tie and forcing extra time.
