Migrate from Amazon Nova 1 to Amazon Nova 2 on Amazon Bedrock
AWS's new Nova 2 Lite model delivers 300% faster search and 70% cost cuts for Siemens.
AWS is urging developers on Amazon Bedrock to migrate from their first-generation Nova 1 models to the newly available Nova 2 Lite. This isn't just an incremental update; it's a strategic consolidation where the 'Lite' tier now outperforms the older, more expensive Pro and Premier models in key areas. Nova 2 Lite dramatically expands the context window from 300K to 1 million tokens, enabling the processing of much longer documents. Crucially, it introduces 'extended thinking' for complex reasoning, along with built-in tools for web grounding and code execution, features that were previously constraints for Nova 1 users.
For existing customers, the migration path is compelling. AWS recommends that users of Nova 1 Pro and even the top-tier Nova 1 Premier migrate to Nova 2 Lite. According to AWS's technical report, Nova 2 Lite surpasses Nova 1 Premier in multi-step problem-solving while being up to 7x cheaper and 5x faster. Real-world impact is already evident: Siemens reported a 300% improvement in search speed and 70% cost reduction after switching their global search to Nova 2 Lite. The model is designed for high-throughput production use cases like intelligent document processing (IDP), customer support automation, and NLP tasks, offering a significant leap in price-performance for agentic AI applications.
- Nova 2 Lite expands context to 1M tokens and adds built-in web search & code interpreter tools.
- AWS recommends Nova 1 Pro/Premier users migrate to Nova 2 Lite for up to 7x lower cost and 5x faster inference.
- Siemens achieved a 300% search speed boost and 70% cost cut by deploying Nova 2 Lite in production.
Why It Matters
Delivers flagship model performance at a 'Lite' tier price, dramatically reducing AI operational costs for enterprises.
