Introducing the next generation of Amazon OpenSearch Serverless for building your agentic AI applications | Amazon Web Services

Amazon’s next-generation OpenSearch Serverless is a managed search and vector engine optimized for agentic AI applications. It scales from zero to thousands of requests per second, creates resources in seconds, and can reduce costs by up to 60% compared with clusters provisioned for peak demand. The release is generally available across supported AWS commercial Regions and integrates with tools such as Vercel, Kiro, Claude Code, and Cursor.

Elastic Scaling and Cost Optimization

• Scales capacity up to 20 times faster than the previous generation.
• Supports scale-to-zero when idle, minimizing compute costs.
• Charges separately for compute through OpenSearch Compute Units (OCUs), storage in GB-month, and GPU acceleration where applicable.
• Supports capacity limits for indexing and search, with minimum capacity set to zero and configurable maximums.

Creating Next-Generation Collections

• Collections can be created through the Amazon OpenSearch Service console, AWS CLI, or SDKs.
• The console’s Express create option automatically applies default settings and matching security policies.
• At launch, supported collection types are:
  • Full-text search (SEARCH)
  • Vector search (VECTORSEARCH)
• Users who need the existing infrastructure can select the classic OpenSearch Serverless generation.
• Collections inherit their generation from a parent collection group.

Example CLI workflows create a next-generation collection group with standby replicas and then create a search collection within it.

Integrations for Agent Development

• Vercel users can create or connect OpenSearch Serverless collections directly from the Vercel console.
• OpenSearch Agent Skills bring search-specific knowledge, best practices, and multi-step workflows into agents using Claude Code, Cursor, and Kiro.
• Kiro’s OpenSearch Launchpad provides guided architecture planning for building search applications.

Availability

• The next generation is generally available in all AWS commercial Regions where OpenSearch Serverless is currently offered.
• AWS recommends consulting the OpenSearch Serverless documentation and pricing information for configuration and cost details.

The release is intended to let developers deploy production-ready search and vector backends quickly, while avoiding the infrastructure management and peak-capacity costs associated with provisioned OpenSearch clusters.
