Noam Rozen

Hybrid Transformer–Mamba language models (Jamba)

Algorithms developer working on MRKL-style systems and hybrid LLMs

A useful long-tail AI21 page because it ties one of the less-public contributors to the company’s modular reasoning and hybrid-model line instead of leaving the profile as a generic Jamba coauthor page.

Worth knowing because his work links earlier dense-retrieval research to later MRKL and Jamba systems, which makes his page a good bridge between classic NLP retrieval and newer hybrid LLM stacks.

Hybrid Transformer–Mamba language models (Jamba)

An especially valuable page for understanding how AI systems get judged in practice, because it puts human evaluation and rubric design at the center rather than treating them as an afterthought to model building.

A field-shaping figure for agentic AI and multi-agent reasoning long before the current LLM cycle, and now one of the clearest bridges between that older intellectual lineage and AI21’s frontier-model work.
