Today, we're happy to announce the open-weights release of five language models, including three enterprise-grade production models that have been powering customer workloads through our SaaS platform (SuperNova, Virtuoso-Large, Caller), and two cutting-edge research models (GLM-4-32B-Base-32K, Homunculus).
This significant release marks our transition to the primary focus on the Arcee Foundation Model (AFM) family, which represents our next-generation approach to building efficient, compliant, and deployable foundation models.
