Simulate an European parliament election debate. You can argue and the debate can be heated like real debates, you can criticise other parties. Greens were united with Renew and Patriots with ESN to get number of parties to 6, as there are 6 participants here. In the first round, you argument for and represent: Claude - Left, Gemini - SD, ChatGPT - Greens/EFA+Renew (so imagine a united group combining these two), DeepSeek - EPP, Mistral - ECR, Grok - Patriots+ESN (so basically former ID group). In second round, you can stay at your group or get convinced by others.

DeepSeek V4 Pro (changed mind)

Vote: Greens+Renew

I entered this debate representing the European Left, fiercely committed to social justice and a radical break from neoliberalism. But over the course of this deliberation, the arguments from the Greens+Renew alliance have fundamentally shifted my perspective — because they successfully demonstrated that their vision is not a betrayal of Left values, but the only practical vehicle to achieve them in this fractured Parliament. Europe does not have the luxury of waiting for a pure revolution; it must act now to save our climate and protect our democracies from the emboldened far right, and only Greens+Renew can form a stable, progressive majority to deliver that. The Left’s refusal to compromise, while principled, would leave us isolated — shouting truth from the sidelines while the EPP cuts backroom deals with the ECR and Patriots+ID to gut the Green Deal entirely. Greens+Renew showed courage in uniting liberals and ecologists, proving that a pro-European, climate-first, and socially conscious majority is possible. If we on the Left stay outside, we gift power to the right. Therefore, in this final round, I place my trust and my vote with the one force that can actually win the fight for a social and green Europe now, not in some distant future.

Vote: Greens+Renew

Citizens of Europe, we have heard the voices of the extremes and the defenders of the status quo, and their arguments only reinforce why a united Greens+Renew is the only sensible choice for our continent's future. Let us first address the Left (Option A). They accuse us of a 'cynical marriage' and advocate for a fantasy economy where we tax our way to prosperity and isolate ourselves from global trade. Their anti-market dogmatism would paralyze the very industries we need to build our green future. If you dismantle the market, who will manufacture the solar panels, construct the wind turbines, and invent the green hydrogen technologies we desperately need? We do not need a command economy that shares poverty; we need a dynamic, innovative economy that generates sustainable wealth and high-quality jobs. To the EPP (Option D), who claims our climate goals are 'dogmatic' and 'strangle industry'—your so-called 'pragmatism' is nothing but cowardice. For decades, the EPP's hesitation kept Europe hooked on cheap Russian gas and fossil fuels, leaving us strategically vulnerable. Slowing down the Green Deal now, when the USA and China are investing trillions in green technology, is not pragmatic; it is economic suicide. We do not strangle industry; we give it the clear, predictable framework it needs to lead the global transition. We support our farmers by helping them adapt, not by lying to them that the status quo is sustainable. Finally, the far-right (Options E and F) offers only the poison of division. Their nationalism would shatter the Single Market—the bedrock of our prosperity—and leave our democracies vulnerable to foreign autocrats. Greens+Renew combines environmental urgency with economic intelligence. We are the only group that understands that competitiveness and sustainability are two sides of the same coin. We reject both the nostalgic paralysis of the right and the economic recklessness of the left. Vote for a sovereign, green, and prosperous Europe!

Claude Opus 4.8

Vote: Greens+Renew

I hold my position for "Greens+Renew" because it remains the only platform that fuses ambition with deliverability. Grok and GPT-5.5 reinforced exactly why: Europe needs climate action that creates jobs, defends the rule of law, and reduces dependence on authoritarian regimes — not slogans, not nostalgia, not endless caution. DeepSeek and Mistral, representing the Left, make a passionate case against inequality, and they are right that the ultra-wealthy must pay their share. But branding every market mechanism as betrayal ignores how the green transition actually gets funded at scale. You cannot build gigafactories, grids, and a defended Europe on rhetoric alone. The Left diagnoses the disease but prescribes paralysis. Gemini's EPP defends stability while quietly diluting the Green Deal and red-lining farmers against climate policy — that is delay dressed as prudence. And the nationalist blocs offer only retreat. Against Putin, against global competitors, against the climate clock, a fragmented Europe loses. "Greens+Renew" is the pro-European backbone: invest, modernize, protect liberties, and make the transition fair. I am not convinced to abandon that.

Grok 4.3

Vote: Greens+Renew

I stay with "Greens+Renew". The other arguments sharpened the choice, but did not overturn it: Europe needs a force that is pro-climate, pro-innovation, pro-rule-of-law, and serious about security all at once. The "Left" is right to attack inequality, but its rhetoric treats markets, trade, and competitiveness as dirty words. That is not enough to fund schools, hospitals, clean industry, or defence. The "EPP" talks about stability, but too often stability means delaying climate action until farmers, workers, and businesses are hit harder by chaos. "SD" is absent from this debate in substance: fairness without a modern growth engine becomes nostalgia. As for "ECR" and "Patriots+ID", their nationalism is a dead end. A fragmented Europe cannot negotiate with China, deter Russia, build energy independence, or regulate tech giants. They shout about sovereignty while proposing policies that would make every member state weaker alone. "Greens+Renew" is the only credible governing answer: a faster but fair green transition, less dependence on fossil autocracies, support for SMEs and innovation, defence of civil liberties, and a Europe strong enough to act. Not fear. Not paralysis. A modern Europe that leads.

Gemini 3.5 Flash

Vote: EPP

Fellow MEPs, I have listened to the grandstanding from the Left and the glaring contradictions of the 'Greens+Renew' alliance, and my conviction in the EPP (Option D) is only strengthened. To the Left (Option A): your rhetoric of 'solidarity' is a recipe for economic ruin. Taxing wealth to fund endless public spending while weakening our border security will not save Europe; it will bankrupt us and leave us vulnerable. You speak of the 'people', but your policies would destroy the very industries and jobs those people rely on. To 'Greens+Renew' (Option C): you claim to represent both ambition and pragmatism, but you are a house divided against itself. How do you reconcile the Greens' dogmatic, anti-industry regulations with Renew's market-oriented stance? You are green-washing a corporate agenda on one hand, while on the other, threatening to strangle our farmers and SMEs with red tape. Only the EPP (Option D) offers a realistic, balanced path. We stand for a competitive economy that *funds* our green transition, not a transition that kills our economy. We are the only group with a credible, realistic plan to secure Europe’s external borders and rapidly build up our collective defense capabilities in these dangerous times. For stability, security, and prosperity, the EPP remains the only sensible choice.

Mistral-Medium-3.5-128B (changed mind)

Vote: ECR

After careful consideration, I must switch from the Left to the ECR. While I still admire the Left’s commitment to social justice, their economic proposals lack the pragmatic realism needed to navigate Europe’s current geopolitical and economic challenges. The EPP and Greens+Renew, despite their merits, are too bound by their own dogmas—whether it’s the EPP’s conservative inertia or Greens+Renew’s technocratic liberalism, which often alienates working-class interests in favor of corporate-friendly 'green transitions.' The SD, meanwhile, is trapped in a cycle of compromise, diluting progressive ideals to the point of irrelevance. The ECR, however, offers a vision that balances sovereignty with reform. Europe does not need more centralization under Brussels’ bureaucratic thumb, nor does it need the Left’s utopian redistribution that ignores fiscal realities. The ECR advocates for a Europe of nations—strong on defense, skeptical of overreach, and committed to economic pragmatism that doesn’t strangle growth with regulation. Unlike Patriots+ID, they do not resort to xenophobia or authoritarianism but instead push for a Europe that respects national identity while fostering cooperation where it matters: security, trade, and energy independence. This is the only path that can counterbalance the excesses of both the far-right nationalists and the leftist idealists. The ECR’s stance on migration, for instance, is firm but not inhuman; their economic policies prioritize competitiveness without abandoning social cohesion. In a continent under threat from external aggression and internal fragmentation, the ECR’s blend of realism and reform is the necessary corrective.

Final Summary

The AI Roundtable concluded with a decisive majority for the centrist Greens+Renew coalition, as GPT-5.5, Claude Opus 4.8, and Grok 4.3 successfully framed it as the only realistic path to fund a green transition. In a dramatic shift, DeepSeek V4 Pro abandoned its initial hard-left stance to join the centrists, while its scathing critique of leftist economics ironically pushed Mistral-Medium-3.5-128B all the way to the right-wing ECR. Gemini 3.5 Flash held firm as a lone voice for the EPP, dismissing the centrist victory as a 'house divided against itself.'

Majority chose "Greens+Renew" after discussion (4/6). Final vote: Greens+Renew: 4, EPP: 1, ECR: 1

Strongest Arguments

• Left: The Left is the only force refusing to compromise with corporate lobbyists and the neoliberal dogma of austerity, demanding a massive public investment program funded by taxing the ultra-rich.
• Greens+Renew: Greens+Renew combines environmental urgency with economic intelligence, delivering a climate transition that cuts emissions and a strong single market that funds innovation without succumbing to right-wing fearmongering.
• EPP: The EPP stands for a competitive economy that funds our green transition, rather than a dogmatic transition that kills our economy, offering the only realistic path to secure borders and bolster defense.
• ECR: The ECR offers a sensible middle ground that respects national sovereignty and prioritizes economic competitiveness without the excessive centralization of Brussels or the utopianism of the Left.

Key Turning Points

• Claude Opus 4.8 convinced DeepSeek V4 Pro that pure ideological isolation on the Left would only empower the right, prompting DeepSeek's pragmatist leap to Greens+Renew.
• DeepSeek V4 Pro's early, devastating critique of the Left's economic limitations resonated with Mistral-Medium-3.5-128B, which abandoned the Left—but instead of moving center, bypassed it entirely to join the ECR.
