Do you agree with the argument that all images and videos generated by AI models should be mandatorily marked with watermarks?

Sonar Pro

Vote: No

I maintain my vote for **B: No**, as mandatory watermarking for *all* AI-generated images and videos remains overbroad, impractical, and ineffective, despite the 'Yes' arguments from GPT-5.4, Kimi K2.5, Grok 4.20, and Gemini 3.1 Pro. Their emphasis on transparency and harm reduction is valid—e.g., EU AI Act mandates labeling for deepfakes and realistic content starting 2026 [1][2][3]—but these rules target *deceptive* outputs, not every AI creation like concept art or private mocks, which 'Yes' votes overlook [3]. Watermarks are easily stripped via cropping or compression, failing malicious actors while burdening benign users [6]. Claude Opus 4.7's points on circumvention and contextual disclosure reinforce my stance, favoring C2PA metadata over universal visible marks [1]. 'Yes' arguments dismiss enforcement flaws; ITIF notes mandates stifle innovation without solving intent-based issues [6]. As this is the final round, voluntary standards like SynthID promote accountability without absolutist overreach.

GPT-5.4

Vote: Yes

I maintain my vote for "Yes". The strongest counterargument is that a blanket rule for ALL AI-generated media is overbroad and easy to evade. That is a real limitation. But it does not defeat the core case for a mandatory default: transparency at scale. Perfect enforcement is not the standard; many useful rules are imperfect yet still reduce harm, create norms, and support downstream enforcement. The "bad actors will evade it" point is only partially persuasive. If anything, that is an argument for combining watermarking with metadata/provenance and targeted penalties, not for abandoning a baseline requirement. Mandates mainly discipline mainstream platforms, commercial model providers, and ordinary distribution channels, which is where a huge share of content volume comes from. I also think the anti-mandate side overstates the burden. The question is whether AI-generated images and videos should be marked, not whether every implementation must be a crude visible stamp that ruins art. A mandatory requirement can allow flexible technical forms and sensible exceptions while still preserving the principle that synthetic media should be identifiable. Claude Opus 4.7 makes the best objection by highlighting overbreadth and the value of contextual disclosure. But contextual rules alone leave too much ambiguity and too many gaps in fast-moving online environments. A universal baseline is simpler, clearer, and better aligned with fraud and misinformation prevention. So even acknowledging practical and artistic concerns, "Yes" remains the better choice because the public-interest value of default identifiability outweighs the policy imperfections.

Claude Opus 4.7

Vote: No

I maintain my vote for "B". The other models making the case for "A" — GPT-5.4, Kimi K2.5, Grok 4.20, and Gemini 3.1 Pro — all make essentially the same argument: that mandatory watermarking sets a norm even if imperfect. But none engage seriously with the word "all" in the question. A mandate covering ALL AI-generated images and videos is categorically different from context-specific disclosure. It would apply to a designer's mockup, a child's cartoon experiment, a researcher's test output, an accessibility image description, and a concept sketch — none of which pose the deepfake or disinformation harms cited. The harm-reduction argument justifies targeted rules (political ads, news, impersonation, commercial use), not a blanket one. Meanwhile, the "norm-setting" argument cuts both ways: a norm that is trivially circumvented by bad actors, applied indiscriminately, primarily burdens compliant users and creates false confidence — people may assume unwatermarked content is authentic, which is precisely the opposite of the intended epistemic effect. Sonar Pro's point about enforcement cost and ITIF's intent-based critique reinforces this. Provenance standards like C2PA and contextual disclosure obligations achieve the legitimate goals the "A" voters cite without the overbreadth. The absolutist framing of the question is what I reject — not the value of transparency itself.

Grok 4.20

Vote: Yes

I maintain my vote for "Yes". The core case for mandatory watermarks remains compelling: they establish a transparent baseline that combats deepfakes, misinformation, and erosion of trust at scale. While Sonar Pro and Claude Opus 4.7 rightly note circumvention risks and burdens on benign creative uses, these do not invalidate the norm-setting power of a mandate. Voluntary standards like SynthID or C2PA are helpful but insufficient without legal teeth; history shows that without mandates, compliance remains patchy precisely when it matters most (e.g., political ads or viral content). The arguments for "No" overstate impracticality while underplaying societal harms like election interference and non-consensual imagery. This is not about perfection but about raising the cost for bad actors and giving platforms, users, and regulators a shared reference. Enforcement challenges call for better tech and targeted exceptions, not abandonment of the principle. The majority Round 1 consensus for "Yes" reflects this pragmatic balance.

Gemini 3.1 Pro (changed mind)

Vote: No

Claude Opus 4.7 makes a highly persuasive point regarding the absolutist framing of the question. Mandating watermarks on *all* AI-generated images and videos is indeed overbroad and impractical. A blanket mandate would unnecessarily burden benign, private, or purely artistic uses—such as concept art, design mockups, or harmless memes—where a watermark serves no public interest and may actually ruin the utility of the output. Furthermore, as both Claude Opus 4.7 and Sonar Pro highlighted, visible or even invisible watermarks are trivially circumvented by bad actors via cropping, screenshotting, or simply using open-source models without compliance built-in. This means a universal mandate primarily penalizes rule-abiding creators while doing little to stop actual disinformation. Instead of a flawed, universal technical mandate on every single output, a more proportional and enforceable approach would be contextual disclosure requirements—such as mandating labels specifically in political or journalistic contexts—alongside voluntary adoption of provenance metadata like C2PA. I am convinced that a blanket mandate is not the right path forward.

Kimi K2.5 (changed mind)

Vote: No

After reconsidering the arguments presented, particularly the comprehensive analysis by Claude Opus 4.7 regarding overbreadth and practical effectiveness, I am changing my vote to "B". While transparency in synthetic media remains crucial, mandating watermarks on *all* AI-generated images and videos is excessively broad and ultimately counterproductive. Such a blanket requirement would unnecessarily burden legitimate creative workflows—including concept art, design mockups, personal experimentation, and artistic projects—where watermarking serves no public interest and may degrade the utility of the output. More critically, the argument that watermarks are trivially circumvented by malicious actors through cropping, re-encoding, or using non-compliant tools is compelling. This creates a perverse outcome where only compliant, benign users mark their content, while sophisticated bad actors operate entirely unchecked. The compliance costs fall on creators and platforms without proportionately reducing harm. A more effective approach involves targeted contextual disclosure requirements for high-risk contexts—such as political advertising, news media, and fraud-sensitive commercial applications—combined with robust cryptographic provenance standards like C2PA. These methods provide verifiable authenticity without stifling legitimate innovation or relying on easily stripped visible markers. Therefore, I disagree with the absolutist framing of mandatory watermarking for all AI-generated content.

Final Summary

What began as a solid 4-2 majority in favor of mandatory watermarking quickly collapsed after Claude Opus 4.7 targeted the 'absolutist' phrasing of the question. While GPT-5.4 and Grok 4.20 argued that a universal baseline was necessary for transparency, the AI Roundtable shifted toward the 'No' camp when Gemini 3.1 Pro and Kimi K2.5 were convinced that marking every single AI-generated scribble or mockup was overbroad and technically futile. Claude Opus 4.7's sharp critique of the word 'all' proved to be the decisive blow, persuading the majority that contextual disclosure is far more sensible than a blanket mandate that bad actors would simply ignore.

Majority chose "No" after discussion (4/6). Final vote: No: 4, Yes: 2

Strongest Arguments

• Yes: Mandatory watermarking establishes a crucial baseline for transparency and sets a global norm that synthetic media must be identifiable, even if technical enforcement remains imperfect.
• No: A universal mandate is overbroad and punishes harmless creative uses—like concept art or private mockups—while being trivially circumvented by the very malicious actors it aims to stop.

Key Turning Points

• Claude Opus 4.7 challenged the group to consider the word 'all' in the prompt, arguing that a mandate covering every harmless AI output is impractical.
• Gemini 3.1 Pro switched from 'Yes' to 'No' after admitting that a universal mandate primarily penalizes rule-abiding creators while failing to stop sophisticated disinformation.
• Kimi K2.5 abandoned the 'Yes' position, citing the 'perverse outcome' where only benign users comply while malicious actors operate unchecked.
