About
Jurassic-2 Ultra by AI21 Labs is their most advanced large language model, designed for intricate text generation tasks that demand high-quality output. It is specifically optimized for "zero-shot" prompts, meaning it performs well without requiring example inputs—making it perfect for chatbot and conversational applications. As the flagship model in the Jurassic series, it features over 60 billion parameters and supports multiple languages such as English, Spanish, and French. While its primary strengths are in text completion, generation, and summarization, it also excels in tasks like question answering and advanced information extraction. Trained on a vast array of texts, including curated CommonCrawl and Wikipedia data, it was exposed to about 1.2 trillion tokens. However, users should be mindful of potential inaccuracies, biases, and its July 2022 knowledge cutoff. Despite these considerations, Jurassic-2 Ultra is widely used in various applications, including AI21’s Wordtune, to enhance reading and writing experiences.
Jurassic-2 Ultra is a model in the Jurassic-2 family. The structured metadata tracks a 8k-token context window and structured outputs. This page tracks provider routes through AWS Bedrock and AI21 Studio, with the cheapest tracked route listed at $18.8 input and $18.8 output per 1M tokens.
