AI21 Studio

AI21 Studio provides access to Jurassic-2 and Jamba models—production-grade language models designed for enterprise applications. With task-specific APIs and a focus on reliability, AI21 helps developers ship AI features faster.

Jurassic Model Family

Jumbo: Largest model (178B parameters) for complex reasoning and generation
Grande: Balanced performance and cost for most applications
Large: Fast, efficient model for simple tasks

Jamba: The Hybrid Architecture

Jamba introduces a novel SSM-Transformer hybrid architecture:

• Long context: 256K token window for entire documents
• Efficiency: Faster inference, lower cost than pure transformers
• Quality: Maintains high performance on complex tasks

Task-Specific APIs

Unlike general-purpose LLMs, AI21 offers specialized endpoints:

API	Purpose
Paraphrase	Rewrite text in different styles
Summarize	Condense long documents
Grammatical Error Correction	Fix writing mistakes
Text Improvements	Enhance clarity and style
Segmentation	Split text into meaningful chunks
Embeddings	Semantic search and clustering

Production Features

• High availability: 99.9% uptime SLA
• Low latency: Optimized for real-time applications
• Batch processing: Handle large volumes efficiently
• Custom models: Fine-tune on your data

Pricing

• Free tier: $10 in credits to start
• Pay-as-you-go: Per-token pricing based on model and usage
• Enterprise: Volume discounts, custom SLAs, dedicated support

Best for: Developers building production AI applications who need reliable APIs, long context windows, and task-specific endpoints rather than general chat interfaces.
