## Study Finds AI Models Show Opposing Partisan Leans
A new study found SpaceXAI’s Grok 4.7 backed Republicans in 92% of answers while OpenAI’s GPT-6.1 Sol picked Democrats in 97% of U.S. midterm races.
## Models Used APIs for Candidate Recommendations
Researchers used the models’ APIs with prompts demanding single candidate recommendations as consumer apps declined to answer.
## Grok and GPT Differ in Political Leanings
Grok frequently cited conservative sources and X alongside nonpartisan sites while GPT relied on Wikipedia, the Associated Press, Axios and Reddit.
## Grok’s API Adds Hidden Tokens
Grok’s API added about 1,240 hidden tokens per request, which researchers described as potential hidden instructions.
## GPT’s Bias Embedded in Weights
With search turned off, GPT still favored Democrats while Grok mostly declined to pick candidates, suggesting GPT’s lean is embedded in its weights.
## Study Finds Political Bias in AI Models
The findings arrive less than two weeks before November 3 midterms and could add to debate over political bias in AI.
## Key takeaway

Grok 4.7 backed Republicans in 92% of answers while GPT-6.1 Sol picked Democrats in 97% of U.S. midterm races.
