LLM4Decompile is an open-source large language model designed for binary code decompilation, transforming binary/pseudo-code into human-readable C source code through a two-phase process. It offers various model sizes and supports decompilation for Linux x86_64 binaries with different optimization levels, demonstrating significant improvements in re-executability rates over previous versions. The project includes training datasets and examples for practical use, showcasing its commitment to enhancing decompilation capabilities across various architectures.
