UnlikelyAI brings decades of expertise in AI development and innovation. UnlikelyAI’s mission is clear:

Deliver all the transformative capabilities of modern AI while ensuring complete reliability, accuracy, and transparency.


We achieve this through our groundbreaking technology that eliminates common AI pitfalls such as incorrect results, hallucinations, bias, and black-box decision making.

At the heart of our innovation is UL (Universal Language), a highly expressive language for machines that bridges the gap between machine learning and completely reliable computing. This revolutionary technology acts as a bridge between the probabilistic world of ML, where accuracy is never guaranteed and errors are considered business-as-usual, and the deterministic world of symbolic systems, where incorrect outputs are extremely rare and considered to be bugs. The broad term for this approach is neurosymbolic and UnlikelyAI are pioneers in this space, applying it to LLMs and modern generative AI before anyone else.

Our team combines deep technical expertise with a commitment to responsible AI development. We partner with enterprises that demand not just powerful AI capabilities, but also complete confidence in their AI systems' outputs and decision-making. Our customers are often in regulated industries where trust is paramount.
