Unraveling the Mystery: Why OpenAI’s o1 AI Model Thinks Multilingually
When OpenAI unveiled its o1 AI model, heralded for its reasoning capabilities, an intriguing anomaly began to surface. Users observed that the model sometimes switched languages mid-thought, using Chinese, Persian, or others, even when questions were posed in English. For instance, when asked “How many R’s are in the word ‘strawberry?’” the model would initiate its reasoning process in English but mysteriously integrate another language before concluding.
The Curious Case of Language Switching
This phenomenon puzzled users across platforms like Reddit and X, with many wondering why o1 would unexpectedly think in Chinese without any prior language cues in the conversation. Despite numerous discussions and social media musings, OpenAI has remained silent on this peculiar behavior.
Theories from AI Experts
In the absence of an official explanation, AI experts have speculated about possible reasons. A prevalent theory suggests that o1’s behavior is influenced by its training data. Clément Delangue, CEO of Hugging Face, and Ted Xiao from Google DeepMind point out that large datasets containing Chinese characters might be a factor. Moreover, companies like OpenAI reportedly use Chinese data labeling services for their diverse datasets.
Labels play a crucial role in helping models understand and interpret data during training. However, as studies indicate, biased labels can lead to biased outcomes. This labeling influence is not limited to Chinese; o1’s linguistic shifts might occur with Hindi or Thai as well, suggesting a broader pattern rather than specific language bias.
“The model doesn’t know what language is, or that languages are different. It’s all just text to it.”

Understanding AI Language Processing
Unlike humans who process words directly, AI models use tokens—units that can be whole words or parts of them (syllables or individual characters). These tokens can inadvertently introduce biases similar to labeling practices. For example, some translators may misinterpret spaces as word separators in languages that do not use spaces conventionally.
Tiezhen Wang from Hugging Face believes these language nuances reflect the associations models form during training. He notes personal preferences for languages in specific contexts—like doing math in Chinese due to syllabic efficiency—mirroring how models might optimize their linguistic choices based on learned efficiencies.
The Quest for Transparency
Luca Soldaini from the Allen Institute for AI emphasizes that without transparency in AI system construction, understanding these behaviors remains speculative. The opacity of these systems underlines the need for clarity on how they are built and trained.
Conclusion: A Lingering Enigma
In conclusion, while theories abound about o1’s multilingual thinking pattern—from training data influences to token biases—the exact reason remains elusive. Until OpenAI provides clarity, we are left to ponder why o1 might hum a tune in French while contemplating synthetic biology in Mandarin.
