Understanding Amazon Bedrock model lifecycle

Machine Learning Blog



This article explains Amazon Bedrock's model lifecycle management, covering three states (Active, Legacy, End-of-Life) and strategies for migrating AI applications as foundation models evolve.

  • Models progress through Active, Legacy, and End-of-Life states with clear timelines
  • Legacy models receive 6 months' advance notice before End-of-Life date
  • Extended access phase allows 3+ additional months of usage after Legacy period
  • Pricing may adjust during extended access; existing agreements remain unchanged
  • Notifications sent via email, AWS Health Dashboard, console alerts, and API
  • Migration planning includes assessment, research, testing, and phased deployment phases
  • Update API references, request quota increases, adjust prompts for new models
  • Use side-by-side comparison, shadow testing, and A/B testing before full migration
  • Models remain available minimum 12 months after launch, Legacy for 6+ months

Effective model lifecycle management requires proactive planning, thorough testing, and phased migration strategies to maintain application continuity while adopting improved foundation models.
