Migrate from Amazon Nova 1 to Amazon Nova 2 on Amazon Bedrock

This article provides a comprehensive guide for migrating from Amazon Nova 1 to Amazon Nova 2 on Amazon Bedrock, highlighting improvements and implementation steps.

• Nova 2 Lite is direct upgrade from Nova 1 Lite with expanded capabilities
• Nova 1 Pro users should migrate to Nova 2 Lite for better reasoning at lower cost
• Nova 1 Premier users can migrate to Nova 2 Lite at 7x lower cost and 5x faster
• Context window expands from 300K to 1M tokens; max output from 10K to 65K
• Extended thinking enables multi-step reasoning with low/medium/high effort levels
• Built-in tools include web grounding, code interpreter, and tool use capabilities
• Nova 2 Lite pricing: $0.30 input, $2.50 output per 1M tokens
• API changes minimal; update model ID and configure new features as needed
• High effort reasoning cannot use maxTokens, temperature, topP, or topK parameters
• Use cases: NLP tasks, intelligent document processing, multi-step agentic workflows
• Siemens achieved 300% search speed improvement and 70% cost reduction
• Trellix saw 39% accuracy boost in threat classification with improved tool calling
• Framework support: LangChain and Strands Agents SDK compatible with minimal changes
• Implement phased rollout with shadow testing and A/B testing before full deployment

Migration requires updating model IDs, configuring timeouts for extended thinking, and evaluating outputs on production workloads before deployment.
