Jurassic-2 is now available

We are excited to announce the release of Jurassic-2 (J2), our latest and greatest series of Large Language Models. J2 builds upon the successes of Jurassic-1 and introduces new features and capabilities that set it apart from its predecessor.

The J2 series includes 3 base language models, and 2 instruction-tuned language models, all accessible through the AI21 Studio API:

J2-Jumbo: The largest and most powerful model in the Jurassic series. Ideal for the most complex language processing tasks and generative text applications.

J2-Grande: Offers enhanced text generation capabilities, making it well-suited to language tasks with a high degree of complexity.

J2-Large: Features fast response times and less processing power. Ideal for tasks that require maximum affordability.

J2-Grande-Instruct: Designed specifically for generating text based on minimal context. Highly accurate, and can be fine-tuned to power smart chatbots and other conversational interfaces.

J2-Jumbo-Instruct: Similar to Grande-Instruct, but with superior language understanding and response generation capabilities. Ideal for users with more advanced conversational interface needs.
