Could you build this?
No Mellum is a proprietary family of LLMs developed by JetBrains from scratch or extensive pre-training/fine-tuning for ultra-low latency code completion and inference.
What it would actually take: Developing Mellum requires large-scale foundational or distilled model pre-training on terabytes of high-quality multilingual source code and AST representations. It necessitates massive GPU clusters, deep research into custom architectures (e.g., speculative decoding, state-space models, or heavily optimized transformer variants), and custom inference runtime engineering tailored for zero-lag IDE autocompletion.
