Haladir

Roadmap & Position in Code Intelligence

Automates COBOL modernization with formally verified AI that guarantees translated code is correct.

Company Overview

Builds an AI-powered mainframe modernization platform using RL, LLMs, and formal verification (TLA+) to automate documentation, translation, and verification of legacy codebases like COBOL for regulated enterprises.

What They're Building

The company's public product roadmap & what they're committed to building.

Rosetta AI suite for automated legacy code documentation and COBOL translation. Open-sourced Specula (TLA+ spec synthesis), Mobol (mainframe transactions), and OR-bench-sample. Positioning as "verifiable operational superintelligence."

's Moat:

Formal verification via TLA+ produces provably correct translations, not probabilistically correct ones. For regulated financial institutions running trillions on COBOL, provable correctness is the only acceptable standard. IBM watsonx Code Assistant does not offer formal verification guarantees.

How They're Leveraging AI

LLM-driven code translation

AI-powered automated translation of legacy COBOL codebases into modern programming languages with formal correctness guarantees.

Verified RL for code models

Building reinforcement learning environments with formally verified reward signals to train AI coding models that produce provably correct outputs.

LLM-powered code documentation

AI-driven automated documentation and business logic extraction from undocumented legacy mainframe codebases to preserve institutional knowledge.

AI Use Overview:

Using LLM-driven code translation with TLA+ formal verification, reinforcement learning for code model optimization, and automated documentation generation.
