Our Commentary ​

JetBrains entering the open-source LLM space with a 12B MoE model is interesting. They're known for developer tools, so their perspective on what makes a useful model could be quite practical. I'm always happy to see more players contributing to open-source AI; it keeps the field dynamic and prevents too much centralization. Mellum2 could be a solid option for specific use cases.
