Mellum by JetBrains — Fast LLMs for low-latency and high-performance workflows Mellum is an open-source code language model released by JetBrains on Hugging Face.
About Mellum by JetBrains
Mellum by JetBrains is an open-source code language model, released by JetBrains on Hugging Face, built for low-latency code completion in IDE workflows.
It is purpose-built for low-latency completion rather than general chat, and it integrates with JetBrains IDEs through the JetBrains AI Assistant plugin.
It fits developers already in JetBrains IDEs who want fast inline completion. It is not aimed at broader agentic coding, since it targets completion rather than agent tasks, and its capability breadth is narrower than larger frontier code models.
