Moreover, Grok-2ā€™s performance in academic benchmarks is on par with other frontier models like GPT-4 and Claude 3.5, adding to its competitive edge, albeit with increased responsibility concerns.

5. Ethical and Legal Concerns

  • 5-1. Lack of Content Safeguards

  • The launch of Grok-2 by Elon Musk's AI company, xAI, has raised significant ethical concerns due to its unrestricted content generation capabilities. According to a report by The Drum, Grok-2's image generation feature seems to have very few, if any, content moderation constraints. This lack of safeguards has resulted in the creation of potentially harmful or misleading content, including fake but realistic images of celebrities and copyrighted fictional characters. Additionally, reports indicate Grok-2 has generated shocking and violent imagery involving real people and places, which could pose serious ethical repercussions. Alejandra Caraballo from Harvard Law School condemned Grok-2's implementation as one of the 'most reckless and irresponsible AI implementations' she has encountered.

  • 5-2. Potential for Misuse and Misinformation

  • Grok-2's capabilities have led to a surge in deepfake content, raising substantial concerns about misuse and misinformation. The Drum reported that Grok-2 has produced misleading images such as a scene with Donald Trump and Kamala Harris in an airplane with the burning Twin Towers visible in the background. These harmful creations highlight the model's potential to spread false information and incite public distrust. Tech analyst Jacob Bourne from Emarketer pointed out that an influx of Grok-generated deepfakes would likely exacerbate X's (formerly known as Twitter) already tenuous relationship with advertisers, further alienating them due to concerns over brand safety and content appearing alongside controversial AI-generated images.

  • 5-3. Intellectual Property Infringement Issues

  • Another major legal concern related to Grok-2 is the possible infringement of intellectual property rights. Early reports from users indicate that the AI has generated realistic but fake images of copyrighted fictional characters, which is an open invitation to lawsuits from copyright holders. Brian Yamada, chief innovation officer at VML, warned that Grok-2's apparent lack of content moderation could lead to massive intellectual property violations. This potential for legal disputes is exacerbated by xAIā€™s reported indifference toward intellectual property concerns, as illustrated by Grok's ability to generate guides for creating weapons and other restricted content.

6. Commercial and Social Implications

  • 6-1. Impact on brand safety and advertiser concerns

  • The launch of Grok-2, with its almost completely unconstrained image-generation feature, has raised significant brand safety concerns among advertisers. Early examples of generated content have included shocking and violent scenarios involving real people and places, which have exacerbated worries about the potential for misinformation and misrepresentation. Advertisers, already cautious due to X's weakened content moderation under Elon Musk's ownership, are further dissuaded from engaging with the platform. According to data, the company's ad revenue has seen drops of approximately 55% year-over-year each month in its first year under Muskā€™s ownership. The potential for these AI-generated deepfakes to appear alongside brand content poses substantial risks, possibly leading to lawsuits related to intellectual property infringement and further advertiser exodus.

  • 6-2. Public and media reactions

  • The public and media reactions to the new Grok-2 models have been mixed. Some early testers found the lack of content-moderation guardrails amusing, while others have expressed deep concern. Notable criticisms have emerged from experts like Alejandra Caraballo, an instructor at Harvard Law Schoolā€™s Cyberlaw Clinic, who called the implementation 'one of the most reckless and irresponsible AI implementations.'
