- Use Amazon Bedrock model IDs, e.g. "anthropic.claude-3-opus-20240229-v1:0" for on-demand, or cross-region inference profile IDs like "us.anthropic.claude-opus-4-7-20251101-v1:0". These differ from the public model slug.
- The endpoint template includes a region segment; set the same region in your SDK/client configuration.
- The examples expect AWS_ACCESS_KEY_ID; rename it only if your application config maps the new variable.

About Jurassic-2 Ultra
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.
