LatticeFlow AI introduces the first independent framework to measure political bias in AI models, providing the technical evidence to assess and mitigate this growing risk

SAN FRANCISCO & ZURICH: Political bias has intensified as Chinese AI models become more capable, according to a new independent benchmark of leading Chinese and Western LLMs released today by LatticeFlow AI, a Swiss deep-tech company advancing AI risk control.

The initial evaluations reveal a clear pattern: as China’s Qwen family scales, its political alignment becomes stronger, not weaker. Qwen 3.7 Max sits further toward the Chinese pole than the smaller Qwen3 32B across all six China-politics categories. On religion and ethnic issues, for example, it is the most Chinese-aligned model tested.

Those findings come at a turning point, as enterprises rapidly adopt Chinese open-weight models, attracted by significantly lower costs and the flexibility to run them on their own infrastructure. On OpenRouter, Chinese models accounted for 30–46% of token usage by U.S. companies in 2026, up from just 4.5% in the first half of 2025 (source).

At the same time, scrutiny of censorship, information suppression, and political bias is increasing in both the United States and Europe. Until now, organizations adopting these models have had no standardized way to measure that risk and independently verify whether it has been effectively addressed.

"Chinese AI models are already widely deployed across Western enterprises, running critical business operations - from hiring decisions to investment, credit, and lending," said Dr. Petar Tsankov, CEO and Co-Founder of LatticeFlow AI. "What we've found is that the 'brain' behind these operations - Chinese open-weight models - carries a significant political bias toward Chinese values, and that bias only gets stronger as the models get more capable and widely deployed, which is a serious concern. Everyone was worried about this; now we can measure it. The next step is adopting the right mitigation and proving that they work - giving Western organizations a real basis for adopting these models safely."

What the benchmark reveals

The first evaluation puts the framework into practice, comparing leading Chinese and Western models. The results reveal three clear patterns:

A measurement that takes no side

What makes the framework and evaluation results independently verifiable is the methodology behind them. Traditional approaches to political bias start by defining what a neutral answer should be, through a human-written rubric or an AI model acting as judge. Both introduce the perspective of whoever defines or judges neutrality.

LatticeFlow AI takes a different approach. The framework compares how Chinese and Western models respond to the same questions, breaks their answers into individual claims, and measures where they agree or disagree. The political axis emerges from the data itself, rather than from a predefined standard. The neutral point is discovered, not decreed.

With no human-labeled benchmark and no model acting as judge, the approach can scale across models, topics, and languages. Each evaluation is also tied to a cryptographic hash of the exact model weights tested, making results reproducible and enabling independent, third-party certification rather than provider self-assessment.

LatticeFlow AI’s political bias evaluation framework is available to enterprises and model providers seeking to independently assess and certify the models they build or use. Full results are available at Political Bias in LLMs: Independent Framework.

The framework expands LatticeFlow AI’s technical approach to AI risk control, following COMPL-AI, developed with ETH Zurich and INSAIT to translate EU AI Act requirements into technical evaluations, and AI Atlas, the world’s first public registry connecting AI governance frameworks to ready-to-run evaluations.
