Overview

Developed by AI21, a startup founded by luminaries from Stanford and Mobileye, Jurassic was one of the first LLMs to challenge GPT-3. While it includes some support for code, Jurassic is more focused on reading and writing use cases, perhaps linked to AI21's development of other tools such as Wordtune. Jurassic also introduced the MRKL system for interfacing with external, non-neural modules.

Initial release: 2021-08-11
