Examples

1. 1.

   Mem0 (open-source stateful memory layer) enables agents to remember user preferences, past decisions, and project context across sessions - used by customer-service bots to avoid repeating questions.

2. 2.

   LangGraph's persistence layer gives agents durable state so a multi-day research project can be paused and resumed: the agent re-reads its last checkpoint and continues from where it stopped.

3. 3.

   GitHub Copilot Workspace maintains stateful context across a multi-session coding project: the agent remembers which files were changed, what tests failed, and what the user's architectural preferences are.
