Forced to pick, Grok’s AI model chooses Republicans. OpenAI’s picks Democrats.

What happened: A Convovo study led by Cornell professor Tapan Parikh asked Grok and GPT via their APIs to name one candidate per race. Grok recommended Republicans in 92% of answers, GPT picked Democrats in 97%. Key numbers: Nearly 500 races; models agreed less than 10% of the time. Why it matters: Parikh said GPT's lean appears built into the model weights, while Grok's depends on search terms and sources, and warned such biases can surface in general election questions. OpenAI said the API test does not reflect its consumer app, which declines to recommend candidates.
