Jamba Reasoning 3B
Jamba Reasoning 3B is an AI21 language-model release. A compact reasoning specialization for local devices and efficient long-context agents. Post-training combines supervised, preference, and reinforcement-learning methods to support mathematics, code, instruction following, and general reasoning. The documented default context is 256K; claims of extended 1M processing are not treated as a uniform deployment guarantee. Long context does not guarantee complete retrieval or factual correctness, and deployed throughput depends on hardware, precision, and prompt length.
