AI21 Labs

AI21 Labs builds large language models optimized for enterprise use, including the Jurassic family of models and specialized tools like Wordtune. The platform focuses on business-ready AI with strong multilingual support, factual grounding, and API integrations designed for production applications requiring reliability and compliance.

Best For

Enterprise teams and developers building AI applications that require accurate, fact-based text generation with strong citation capabilities. Ideal for customer support automation, document summarization, content generation, semantic search, and building RAG (retrieval-augmented generation) systems that prioritize factual accuracy.

Perfect for regulated industries (finance, healthcare, legal) where hallucinations are unacceptable, businesses requiring multilingual support across Hebrew, English, and other languages, and teams building knowledge management or question-answering systems.

Key Features

What makes Jurassic models different?
Jurassic models emphasize factual grounding and citation—the AI can point to sources for its claims. This reduces hallucinations and makes outputs auditable, critical for enterprise use. Models are also optimized for instruction-following and long-context understanding (up to 256K tokens).

What is Task-Specific Models?
AI21 offers pre-built models for common tasks: summarization, paraphrasing, grammatical error correction, text improvements, and contextual question-answering. These specialized models often outperform general-purpose LLMs for their specific use case while being faster and cheaper.

Can I build RAG systems with AI21?
Yes. AI21's Contextual Answers API is built specifically for RAG—upload documents, ask questions, and get answers grounded in your data with citations. The platform handles chunking, embeddings, and retrieval, reducing engineering complexity.

What about data privacy?
AI21 offers GDPR compliance, SOC 2 Type II certification, and enterprise data processing agreements. Customer data is not used to train foundation models. Dedicated deployments and on-premises options are available for sensitive workloads.
