You can now use LinkedIn to test out some of the latest AI models from OpenAI, Anthropic, Google, Microsoft and other companies without having to worry about token limits or paying for an extra subscription. The professional network is experimenting with a new feature that allows people to test AI platforms’ latest offerings within LinkedIn.

It’s called Crosscheck, and it’s rolling out now to anyone with a LinkedIn Premium subscription in the United States. The feature is meant to be a kind of “blind taste test” for AI models, according to the company’s Chief Product Officer Hari Srinivasan. Users start with a prompt and get two answers, each of which is provided by a different model. It’s only after choosing which model you like better that you can see the underlying models behind each.

Srinivasan says that Crosscheck is still an “early product” from LinkedIn Labs and that “there’s work to do to make it faster and add more models and question types.” But it already seems to support a fairly wide range of models. In my initial tests of the feature I saw multiple answers generated by Anthropic models, as well as those from Google, MoonshotAI, Mistral and Amazon. Crosscheck will also have its own leaderboard that tracks how people in different industries are rating the various models.

Crosscheck only supports text-based prompts, so you can’t generate images, upload files or use some of the more advanced tools that would be available natively on the AI platforms themselves. But there are no limits on the number of text-based chats you can have, so you don’t have to worry about token limits or signing up for a pricey subscription if you find a model that’s helpful.

LinkedIn is, however, sharing data back to the respective AI companies who will presumably use information gleaned from LinkedIn usage to improve their products. “Anonymized data is shared with model builders to help them understand how their models are performing amongst different occupations,” the company explains. “No personally identifiable information is shared with model builders.”

While Crosscheck is initially only available to LinkedIn Premium subscribers in the United States, the company plans to expand the the feature to more countries and free users “soon.”
