Cohere Releases North Mini Code: 30B MoE Model for Agentic Coding

The article presents Cohere‘s North Mini Code, a 30B Mixture-of-Experts model with 3B active parameters, designed specifically for agentic software engineering tasks and released under Apache 2.

0. A core tension addressed is the challenge of building open-source coding models that generalize reliably across diverse agent harnesses (e.g.

, SWE-Agent, mini-SWE-agent, OpenCode) rather than overfitting to a single benchmark environment.

The authors argue that cross-harness robustness is critical for real-world usability but often neglected in favor of maximizing a single leaderboard score.
