JetBrains open sources its code completion LLM, Mellum

JetBrains has released Mellum, an open-source code completion LLM, on Hugging Face. This focal model specializes in code completion for 14 popular programming languages, offering a cost-effective alternative to larger, general-purpose models. JetBrains plans to expand Mellum into a family of task-specific coding models, making it valuable for AI researchers and educators exploring domain-specific language models in software development.
