The next generation of OpenSearch Serverless creates resources in seconds and scales capacity up to 20 times faster than the previous generation. With instant resource creation and native integrations with AI development platforms like Vercel and Kiro , you can deploy production-ready search and vector backends for your AI agents in minutes without managing infrastructure.
