To protect citizens from the AI-exacerbated spread of misinformation and harm, the government should pass legislation that covers generative AI platforms, bringing them in line with other online services that pose a high risk of producing or spreading illegal or harmful content. Following the Principles identified by this report, this legislation should require generative AI platforms to: provide risk assessments to Ofcom on the risks associated with different prompts and outputs, including how far they can create or spread illegal, harmful or misleading content; explain to Ofcom how the model curates content, responds to sensitive topics and what guardrails are in place to prevent content that is illegal or harmful to children; implement user safeguards such as feedback, complaints and output flagging; and prevent children from accessing inappropriate or harmful outputs. (Recommendation, Paragraph 76)
