AI Model / Code/Workflow Model
JetBrains introduces Mellum2, an open-source 12B model built for software engineering workflows, routing, Q&A, RAG, sub-agents, and private deployment.
The page clearly presents a real AI product with a specific purpose: a fast, open-source model for software engineering workflows. It explains the model’s architecture, intended use cases, performance focus, and deployment fit, giving enough evidence for a useful directory listing.
The page does not show a download link, API endpoint, benchmark table, or setup instructions in the crawl snapshot, so visitors still cannot tell exactly how to try or integrate Mellum2 from this page alone.

A 150M ModernBERT-based token classification model that extracts verbatim evidence spans for RAG and related pipelines, reducing the need for an LLM call to highlight answers.
An open-source 26M parameter function-calling model designed to run on very small devices, with a local quickstart, Python usage, and a playground for testing and finetuning.
