LinkedIn is testing a new AI feature, Crosscheck, which allows users to compare several popular AI models directly on the platform. Users enter prompts into Crosscheck and receive two different responses generated by competing AI models from companies such as OpenAI , Anthropic , and Google . After the user selects the best response, the model behind each answer is revealed. LinkedIn product manager Hari Srinivasan describes the service as a kind of blind taste test for AI models, according to Engadget . Crosscheck works only with text, but has no limits on the number of questions. At the same time, LinkedIn shares anonymized user data with the AI companies to provide insights into how the models perform across different professional groups. The feature is initially available to LinkedIn Premium subscribers in the US, with plans to expand to more countries and free users soon.
