About

Jamba Mini 1.7 is the compact member of AI21 Labs' Jamba open model family, built on a hybrid architecture blending Transformer attention layers, Mamba state-space layers, and Mixture-of-Experts. At 52B total parameters with 12B active, it keeps the family's 256K-token context window while targeting single-GPU deployment.

The 1.7 update focuses on improved grounding and instruction-following, delivering more context-faithful answers and better steerability for enterprise applications in finance, healthcare, retail, and education. It supports nine languages and is released under the Jamba Open Model License, available on Hugging Face and AI21's API.
