LinkedIn has introduced Crosscheck, allowing premium subscribers to test AI models from companies like OpenAI, Anthropic, and Google without token limits. This "blind taste test" presents two answers to a single prompt, revealing only after selection which model generated each response. The feature represents LinkedIn's entry into the competitive AI evaluation space.

Currently available to LinkedIn Premium users in the US, Crosscheck supports text-based prompts from multiple providers. While lacking image generation capabilities, the platform offers unlimited text-based chats. LinkedIn shares anonymized data with AI companies to help them improve performance across different occupations.

LinkedIn's Chief Product Officer Hari Srinivasan acknowledges Crosscheck as an "early product" with plans for expansion. The feature includes an industry-specific leaderboard tracking model preferences. This initiative gives professionals a unified testing ground for AI capabilities while providing valuable feedback to developers.
