Jamba Tiny Dev

Jamba Tiny Dev is a small trained checkpoint for architecture development and debugging. AI21 reports 319 million parameters and training on about 40 billion tokens.

Research release

A development model rather than a small assistant

The card says the model was not extensively trained and should not be expected to produce high-quality text. Its purpose is to make work on the architecture easier.Jamba-tiny-dev official model card

Useful experiments need a narrow question

Practical guidance. Use a checkpoint like this to inspect loading, training behavior or architectural changes. Do not use its output quality as a measure of the full Jamba family. This trained checkpoint is different from a repository containing randomly initialized weights.
