Today, we are introducing Jamba2, an open source family of language models built for maximum reliability and steerability in the enterprise, [the company said on 8 January 2026](https://www.ai21.com/blog/introducing-jamba2?ref=ai-360.online).

AI21 Labs: Introducing Jamba2: The open source model family for enterprise reliability and efficiency, the company said on 8 January 2026\. Built on our novel SSM-Transformer architecture , and a category leader across grounding and instruction following benchmarks, Jamba2 offers a compact, memory-efficient addition to any production agent stack, able to power precise question answering workflows that don’t call for the heavy “thinking token” overhead of reasoning models. Jamba2 is available in two model sizes: 3B and Mini (MoE; 12B active, 52B total parameters).

We are proud to release both under the Apache 2.0 License , as part of our continued commitment to democratizing access to quality models. We are particularly excited this release includes a 3B model, enabling developers everywhere to download and run this technology right on their own devices, including iPhones, Androids, Macs, and PCs.

For enterprise buyers, the useful next step is to map the claim to controls, data residency and measurable outcomes—and to ask for evidence on failure modes, oversight and auditability before treating the release as production-ready fact.
