LinkedIn Crosscheck: Test AI Models for Free Inside LinkedIn
LinkedIn has launched a feature that lets Premium subscribers compare AI models from OpenAI, Anthropic, Google, Microsoft and others, side by side, without paying for separate subscriptions or hitting token limits. The feature is called Crosscheck, and it is rolling out now to LinkedIn Premium subscribers in the United States, with broader availability planned for additional countries and free users. How LinkedIn Crosscheck Works Crosscheck is described by LinkedIn's Chief Product Officer Hari Srinivasan as a "blind taste test" for AI models. The experience works like this: You enter a text prompt
LinkedIn returns two answers, each generated by a different AI model
You choose which answer you prefer
Only after making your selection does LinkedIn reveal which models produced each response The feature already supports a wide range of models. Early testing has returned responses from Anthropic, Google, MoonshotAI, Mistral, and Amazon, with more expected to be added. Crosscheck also has its own leaderboard tracking how professionals across different industries rate the various models against each other. What Crosscheck Does and Does Not Support Crosscheck is currently text-only. You cannot generate images, upload files, or access the more advanced capabilities available directly on each AI platform's native interface. What you do get is unlimited text-based conversations with no token limits, and no requirement to sign up for additional paid subscriptions to access models you want to try. On data sharing: LinkedIn states that anonymised usage data is shared with the AI model providers to help them understand performance across different professional roles and industries. According to LinkedIn's own documentation, no personally identifiable information is passed to model builders. Why This Matters for B2B Content and Advocacy Teams For marketing, content, and employee advocacy teams already working inside LinkedIn, Crosscheck removes a meaningful barrier. Testing whether Claude, Gemini, or GPT-4o produces better output for a specific use case, such as a thought leadership post, a comment response, or a newsletter section, has historically required maintaining multiple subscriptions and switching between platforms. Crosscheck consolidates that comparison inside a platform your team is already using every day. A few practical implications worth considering: For content quality benchmarking. If your team uses AI to support LinkedIn post drafting or employee content kits, Crosscheck gives you a fast, free way to identify which model produces output that resonates with your specific audience and industry vertical. For employee advocates. Employees who are less familiar with AI tools now have a low-friction way to experiment with AI assistance directly inside LinkedIn, without needing separate accounts or training on new platforms. For advocacy programme managers. The Crosscheck leaderboard, broken down by industry, could become a useful proxy for understanding which AI models are gaining traction among your target audience, informing both content strategy and tool selection. What to Watch Crosscheck is currently an early-stage product from LinkedIn Labs, and Srinivasan has acknowledged there is work to do on speed, model range, and supported prompt types. It is also US-only for LinkedIn Premium users at launch, which limits immediate access for UK and European teams. That said, LinkedIn's track record of rolling features out globally after US pilots, combined with the stated intention to extend access to free users, suggests Crosscheck will reach wider audiences within months rather than years. The Bigger Picture for LinkedIn Content Strategy LinkedIn's move to embed AI model comparison directly into the platform is part of a broader pattern. Over the past 18 months, LinkedIn has introduced AI writing assistance, AI-powered post suggestions, and now a structured way to evaluate models against each other, all within the interface where B2B professionals are already spending time. For teams running employee advocacy programmes, this trajectory reinforces a simple strategic point: LinkedIn is becoming a content production and evaluation environment, not just a distribution channel. The tools employees need to create, refine, and share professional content are converging in one place. If your team is not yet building a structured approach to LinkedIn content and employee advocacy, the platform's own investment in AI tooling is accelerating the gap between organisations that are and organisations that are not.
