Reason in a compact DSL
LLMs operate over a terse, structured language designed around compositional semantics rather than verbose implementation detail.
AI + Formal Verification
Verified software from compact symbolic intent.
Lanyon AI is building a new reasoning layer for language models: a highly compact domain-specific language that deterministically expands into executable software and end-to-end proofs of correctness.
The approach
A smaller language for stronger guarantees.
Instead of asking models to directly produce large, fragile codebases and proofs, Lanyon focuses model reasoning into an intentionally compact symbolic interface. That interface is designed to be expanded by a purely symbolic procedure into complete implementations and machine-checkable correctness arguments.
Expand symbolically
The DSL is deterministically elaborated into software artifacts, formal specifications, and proof obligations through a controlled symbolic pipeline.
Ship with correctness
Generated implementations are paired with end-to-end proofs, making reliability a property of the construction process rather than a post hoc aspiration.
The system
Designed for agents that are reliable by construction.
INPUT
Human intent
Requirements are captured as high-level software and proof objectives.
REASONING
Compact DSL
The model reasons in a minimal formal substrate optimized for token efficiency and semantic precision.
OUTPUT
Verified artifacts
A deterministic symbolic expansion produces implementations, specifications, and correctness proofs.
Why now
AI coding needs a verification-native substrate.
As software agents become more capable, the limiting factor shifts from generation to trust. Lanyon is building toward a world where the agent’s output is not merely plausible, but accompanied by a symbolic certificate of correctness.
The goal is not to make language models write more code. It is to make them express less—and prove more.
