LinkedIn has introduced a groundbreaking new feature, Crosscheck, which acts as a “blind taste test” for generative AI models, directly within the platform. Currently available to LinkedIn Premium subscribers in the US, Crosscheck allows users to enter a single prompt and receive two simultaneous, side-by-side responses. Crucially, the identities of the models are hidden. Users are asked to evaluate the outputs based solely on quality and professional relevance. Only after selecting their preferred answer is the name of the AI model revealed—which can include top contenders like OpenAI’s GPT, Google’s Gemini, Anthropic’s Claude, Microsoft’s Copilot, and others.
Why it matters to your readers: This tool simplifies a major workflow challenge. For professionals trying to decide which AI subscription to buy, or which model to use for a specific task (e.g., writing a job description vs. coding), Crosscheck eliminates the need for multiple expensive subscriptions and separate browser tabs. It empowers users to make an informed, unbiased choice based on their actual, real-world work. For the industry, LinkedIn plans to use this anonymous feedback to create a performance leaderboard, offering unique insights into how models perform across different occupations and professional contexts.
