Frontier Research Systems That Hypothesise, Prove & Evolve

The rise of large language models has sparked extraordinary advances in reasoning, code generation, and even mathematical problem-solving. But when it comes to formal logic, provable guarantees, and autonomous discovery LLMs fall short.

 

At Eigenform, we’re building something fundamentally different: a self-improving diffusion model that constructs and tests hypotheses using rigorous formal language like Lean: reasoning not simulating reasoning, with formal verification and adaptive feedback loops at its core.

Generating Knowledge at the Edge of the Unknown

Eigenform is a deep tech AI research organization dedicated to pioneering foundational technologies that push beyond conventional AI limitations.

 

Our models and agents consistently evolve through cycles of goal-setting, strategy implementation, rigorous evaluation, and adaptive learning.

Beyond Human-Derived Data

Current LLMs inherit the ceiling of their training sets.

 

Our agents generate and validate brand-new knowledge – and hence high-entropy data – directly in their environment, guided by an unbounded, ungameable numeric reward, then use the new knowledge to fine-tune themselves.
