Vercel AI SDK Memory overview

Vercel AI SDK's built-in memory system for agent applications (ai-sdk.dev/docs/agents/memory). Provides a structured memory API integrated directly into the AI SDK agent loop — agents can read and write memories using the same tool-use interface as other AI SDK tools. Supports multiple storage backends (KV, Postgres, Upstash) through Vercel's storage adapters. Memory scoping follows the AI SDK user/ session/agent model, with memories persisted in Vercel's managed infrastructure or self-hosted backends. Designed for Next.js-based AI applications where server actions and edge functions serve as the memory persistence layer.
