Memory
A cross-session memory mechanism for AI agents that establishes a persistent storage layer outside the model. It saves user preferences, correction history, and project experience as retrievable notes, enabling agents to accumulate personalized knowledge across different sessions.
Core Facts
The memory module enables an agent to remember context and historical interactions, enabling continuous decision-making.
LangChain introduced two paradigms—chain invocation (Chain) and agents (Agent)—where the former is suited for fixed sequential process tasks and the latter is suited for open-ended tasks that dynamically infer the next step.
Timeline (last 90 days)
Devin's Memory belongs to the semantic layer of long-term memory, while Dreaming is closer to metadata management of long-term memory.
Devin's memory system consists of two mechanisms: Memory and Dreaming.
Cognition's Devin has a mechanism called Memory that can retain awareness of the user's working habits across sessions.
Historical conversations are usually truncated by turns or by a token-count window, to avoid the prompt growing indefinitely and exceeding the model's context length limit or driving up call costs.
When OpenAI's ChatGPT launched the Memory feature, it went through controversy, as the system automatically memorizing user information across sessions caused some users to worry about privacy leakage or information cross-contamination
OpenAI is attempting to build cross-session user profiles through the Memory feature and GPT Actions.
Cognition has launched Memory and Dreaming features for its programming agent Devin.
The Memory and Dreaming features have not yet been independently tested by third parties, and all relevant information comes entirely from Cognition's official announcements.
Content recorded by Memory is saved as brief notes and is exclusive to individual users.
Session ID is used to distinguish different conversation contexts, so that when multiple users are conversing simultaneously, each user's message history is stored separately.

50%UnverifiedAccording to Claude's official documentation, enabling Incognito Chat does not invoke Claude's existing memories.
50%UnverifiedThe content of Incognito Chat will not be incorporated into future memory entries.
50%UnverifiedClaude's Memory feature allows Claude to retain information about the user across multiple conversations, such as occupation, preferences, and habits.
50%UnverifiedWithout a Memory node, each reply from the Agent is independent and cannot be associated with previous conversation content.
50%UnverifiedThe Memory node in n8n uses Window Buffer Memory by default.
50%UnverifiedChatGPT's memory entries are stored at the account level rather than the device level, so the same memory store can be retrieved regardless of which device or network is used when logged into the same account.
50%UnverifiedContext is temporary information for the current task and is discarded when the task ends, while Memory is long-term information retained across tasks; the two must be managed separately.
50%UnverifiedIf incorrect information is saved to long-term memory, it will contaminate subsequent tasks; only truly valuable, confirmed information should be saved.
