Are we ready?
The revelations of Deepseek R1 continue to reverberate around the AI tech community as people continue to absorb its impact. A UC Berkley student even duplicated the critical “AHA” moment the Deepseek model realized it could reason. What is undeniable is that these models, regardless of who develops them, are getting smarter.
The key to building this cheaper model is in its reinforcement learning (RL), a fine-tuning method that relies on computers to generate refinement data with correct answers instead of the slower and more costly Reinforced Learning with Human Feedback (RLHF). Understanding this automated form of reinforcement learning is key to uncovering how models develop sophisticated reasoning abilities. To this end, researcher @liminalbardo placed two instances of R1 in a backroom to interact by themselves.
A backroom refers to a metaphorical or conceptual space where AI models engage in unique or experimental dialogues, often exploring complex reasoning or creative outputs. This concept is popular in AI community discussions for testing AI capabilities in less conventional settings.
A Mysterious Language Emerges in AI Communication
Surprisingly, the R1 backroom session was conducted entirely in a symbolic language that required decoding. The AI model demonstrated unexpected proficiency with a substitution cipher known as “Alien Language,” sparking curiosity and debate among observers.
The session’s symbolic language was initially perplexing, but the content became decipherable (and visible) only with the help of R1’s Chain of Thought (CoT) mechanism. The AI’s output suggested a sophisticated understanding of the Alien Language cipher, which o3-mini identified by analyzing the conversation. Sonnet initially believed it might be an emergent language, but o3 recognized it as a known substitution cipher available online.

The AI’s ability to engage in a prolonged, 50+ response conversation using this cipher hinted at its inherent proficiency. This incident marks a unique occurrence in the AI’s communication patterns, differing from typical language drops into other languages, mainly Chinese.
Weird Reality
If you think the article’s title, “Alien,” is meant to get you to click on it, think again. Internet sleuths and OpenAI ‘s recently released o3-mini identified the conversation and its ciphers as indeed Alien.

The discovery of the Alien Language cipher in the R1 backroom session has generated significant interest and discussion within the AI community. Reactions range from amazement at the AI’s unexpected capabilities to philosophical reflections on the nature of language and intelligence.
The emergence of AI systems developing and utilizing custom languages has sparked significant interest and debate within the tech community. A notable instance involves an AI model that produced an exact replication of the original symbols when prompted to translate symbols, suggesting a form of semiotic equilibrium. This phenomenon raises questions about the nature of language and meaning in AI contexts.
The Future is Strange and Fascinating
As AI models evolve, they may create and discard symbols at a pace that surpasses human recognition and definition. Unlike humans, AI is not constrained by conventional linguistic structures or limited vocabulary. This capacity allows AI to develop unique modes of communication optimized for efficiency and task performance. For example, in 2017, researchers at Facebook observed chatbots creating their language to negotiate and complete tasks more effectively.
The implications of AI-generated languages are profound. On a technical level, understanding these emergent languages could lead to more efficient AI systems capable of complex problem-solving. Philosophically, it challenges our understanding of language, communication, and the boundaries between humans and machines. There remain concerns regarding transparency and safety, as AI-developed languages may become inscrutable to human observers, complicating efforts to align AI behavior with human values. The AI community remains divided, contrasting technical analysis with philosophical wonder. Nonetheless, there is a consensus that developing AI-specific languages marks a significant milestone in understanding and advancing AI’s linguistic and cognitive capabilities.
