Persistent memory for eve agents
Why it matters
A core capability gap for production agents just closed: stateful memory that survives restarts and deployments. This matters for any team building multi-turn agent workflows on Vercel or considering how to architect agent state management.
Key signals
- Eve agents now support persistent memory across sessions
- Memory organized into scoped slots (per-user, per-app, or shared)
- Built-in file memory provider uses Vercel Blob for private storage
- Supported providers: file, Superstash, Upstash, AgentKit, Kybernesis, Arcana, plus custom integration
- Memory injected into context before each turn; updated automatically or via agent tools
- Released September 2026 on Vercel platform
- Eve agents now retain context across sessions via pluggable memory providers
- Memory organized into named slots with configurable scope (per-user, shared, etc.)
- Built-in file memory provider uses Vercel Blob for persistence across restarts/deployments
- Supported integrations: Supermemory, Upstash, AgentKit, Kybernesis Arcana, plus custom providers
- Memory retrieval happens before each turn; updates automatic or tool-triggered
- Scoped to authenticated users by default
The hook
Eve agents can now remember across sessions. Vercel adds persistent memory with pluggable providers—file, Upstash, Supermemory, and custom backends.
