AI21 Labs: The Jamba 1.5 Open Model Family: The Most Powerful and Efficient Long Context Models, the company said on 22 August 2024.

We are releasing these models under the Jamba Open Model License , upholding our commitment to democratizing access to quality models and opening the door to further experimentation.
