Overview

Janus (janus-llm) uses LLMs to aid in the modernization of legacy IT systems. The repository can currently do the following:

1. Chunk code of over 100 programming languages to fit within different model context windows and add to a Chroma vector database.
2. Translate from one programming language to another on a file-by-file basis using an LLM.
3. Translate from a binary file to a programming language using Ghidra decompilation.
4. Generate requirements, UML diagrams, code comments, and summaries from source code.
5. Evaluate the products that you generate.
6. Do 1-5 with a CLI tool (janus).
