Why we tried BSL Mergekit began as a research tool for model merging and post-training. Over time, advanced techniques like fusion and tokenizer surgery lived in a private Arcee fork. We wanted to share that work and invest more in the public library, while preventing large competitors from hosting or commercializing it without engagement. The Business Source License looked like a clean middle path: open enough for the community, protected enough for us. In theory, most developers could continue as before. In practice, any custom license creates gray areas. Even when the answer is \"you're fine,\" the question itself slows adoption. Engineering teams need to route license reviews through legal. Startups hesitate. Contributors wonder if their patches will complicate future use. That uncertainty did not align with how we want to build.
