What is AI21 Studio?

AI21 Studio is the developer platform from AI21 Labs, an Israeli research company. It provides API access to the Jamba family of models, which combine a transformer with a state-space architecture to support long contexts at reasonable cost, along with task-specific tools for summarisation, paraphrasing and grammar. Self-hosted and cloud deployment options suit organisations that need a specific model inside their own environment. It is a smaller catalogue than the major labs offer, chosen mainly for long-document work and for Jamba's memory efficiency.

FAQ

What makes Jamba different?

It mixes transformer layers with a state-space design, which keeps memory use lower as context grows. That makes very long documents more practical to process than with a plain transformer.

Who is AI21?

AI21 Labs is an Israeli AI company that has published research and built the Jurassic and Jamba model families. Studio is its developer platform for accessing those models by API.

Can I run the models myself?

Some deployment options exist for organisations that need models inside their own environment. Availability depends on the model and agreement, so check with the vendor before planning around it.
