When AI Agents Provide Incorrect Suggestions, Who Should Bear the Responsibility?

AI agents are gradually shifting from answering questions to participating in the decision-making process. They can assist users in choosing software, comparing suppliers, recommending application interfaces, screening services, booking tools, or completing purchase operations. This has led to an issue that cannot be avoided in the ecosystem: when the recommendation results are incorrect, who should be held responsible? Not only is it technically incorrect. It is also incorrect in practical operation. The tool does not meet the user's needs. The pricing is outdated. The function description is incomplete. There are hidden limitations in the service. The agent has ignored the key constraints. The user purchased the product based on incorrect guidance. The product data provided by the supplier is inaccurate or misleading. Whose responsibility should it be? Is it the responsibility of the agent developer? Or the model provider? Or the data provider? Or the platform that sorts the options? Or the user who received the recommendation? Perhaps there is no absolutely correct answer. But the way we present the answer will determine how the agent ecosystem is constructed. There seem to be several questions that inevitably need to be answered: \- Should the recommendations include confidence levels? \- Should the agents show the evidence they used? \- Should high-risk categories require stronger warnings or manual review? \- Should the agents save the reasoning process of the recommendations for future auditing? \- Should the suppliers be responsible for inaccurate machine-readable product data? \- How do we protect users while not allowing each developer to bear unlimited responsibility? The internet has made us understand that bad recommendations may be hidden in rankings, advertisements, reviews, and affiliate incentive measures. And the agent may integrate all of this into a firm response. This is indeed useful. But it also brings a new responsibility issue.
