Mellum Goes Open Source: A Purpose-Built LLM for Developers, Now on Hugging Face

Mellum doesn’t try to know everything. It’s designed to do one thing really well: code completion. We call it a focal model – built with purposeful depth and not concerned with chasing breadth.

But code completion is just the start.

Mellum will grow into a family of focal models, each specialized for different coding tasks – from code completion to diff prediction and beyond.

Now, the base model is open-sourced and available on Hugging Face. Whether you’re building tools, running research experiments, or just curious, you’ll have full access to a fast, multilingual model*.

*Mellum supports code completion for Java, Kotlin, Python, Go, PHP, C, C++, C#, JavaScript, TypeScript, CSS, HTML, Rust, Ruby.
