LinkedIn’s Crosscheck Lets Premium Users Compare AI Models for Free

LinkedIn is rolling out a new feature called Crosscheck that allows Premium subscribers in the United States to test cutting-edge AI models from OpenAI, Anthropic, Google, MoonshotAI, Mistral, Amazon, and others—all without worrying about token limits or additional subscription costs.

The tool, currently in early development as part of LinkedIn Labs, functions as a “blind taste test” for AI models, according to Hari Srinivasan, Chief Product Officer at LinkedIn. Users input a prompt and receive two responses generated by different models. Only after selecting a preferred answer are the underlying models revealed.

Srinivasan acknowledged that Crosscheck is still an “early product” and noted that improvements are needed to enhance speed and expand the range of supported models and question types. However, initial tests have already shown support for multiple models, including those from Anthropic, Google, MoonshotAI, Mistral, and Amazon.

Crosscheck also introduces a leaderboard to track how users in various industries rate the different models. Once a user selects a preferred response, LinkedIn displays which model generated each answer.

While Crosscheck supports text-based prompts, it does not allow image generation, file uploads, or access to advanced tools available on native AI platforms. However, the feature imposes no limits on the number of text-based chats, eliminating concerns about token restrictions or costly subscriptions for users who find a model helpful.

LinkedIn will share anonymized data with AI model builders to help them evaluate performance across different professions. No personally identifiable information is disclosed to the companies. The data shared includes insights on how models perform among various occupations.

Initially available only to LinkedIn Premium subscribers in the U.S., the company plans to expand Crosscheck to more countries and free users in the near future.
