AI agent memory is information retained for possible use in a later interaction. It might be a saved preference, a summary of earlier work, a set of files, or searchable chat history. It is not one universal feature: products differ in what they save, how they retrieve it, and what controls they expose. To manage it, find out what is stored, where it lives, and whether turning a feature off also deletes its underlying data.
What does “memory” mean in an AI agent?
Memory is a context layer that lets an assistant or agent reuse information beyond the immediate exchange. Depending on the system, that information may be explicitly saved, distilled from previous work, stored in files or records, or retrieved from earlier conversations when relevant.

Memory is not necessarily the same as a conversation transcript or the temporary state of an active session. OpenAI’s Agents SDK, for example, distinguishes persistent sandbox memory files that preserve distilled lessons from earlier workspace runs from SDK Session memory, which stores message history. Its documentation describes the sandbox feature this way: “Memory lets future sandbox-agent runs learn from prior runs.” That describes a particular SDK feature, not a universal definition.

Storage is not the same as retrieval
A system can retain information without using all of it in every response. Some systems inject a compact summary at the start of a run, search an index when past work seems relevant, and open detailed notes only as needed. OpenAI documents this progressive-disclosure approach for its sandbox SDK. Other products may retrieve context differently. OpenAI Agents SDK: Sandbox memory
#1 Best Overall
In practical terms, memory is selected, retrievable context; what it contains and how it is represented depend on the product. It may be selective, may change over time, and may not be enabled by default.
What can AI memory store?
Different products and implementations retain different kinds of information. Examples include:
- User preferences or facts used to personalize later answers.
- Summaries, corrections, task context, or strategies distilled from earlier agent runs.
- Text documents, files, or structured records that an agent can read or update.
- Information retrieved from prior chats and, where supported for the account, files or connected apps.
These are examples from distinct systems, not a checklist that applies to every assistant. Anthropic’s managed agent memory uses workspace-scoped text documents mounted into agent sessions. OpenAI’s ChatGPT help page says available information sources can vary by account and may include past chats, saved memories, custom instructions, Library files, and connected apps. Neither description means every item is retained verbatim or used in every answer. Anthropic: Give Claude persistent memory and OpenAI: Memory FAQ

Memory vs. chat history: what is the difference?
| Aspect | Chat history | Memory |
|---|---|---|
| What it represents | Messages from conversations, when the product retains them. | Selected information saved, summarized, indexed, or otherwise made available for later use. |
| How it may be used | May be searchable or referenced if the product supports it and the relevant setting is enabled. | May be retrieved when relevant or supplied as a compact summary; the retrieval method varies. |
| Relationship | A product may retain history without creating separate saved memories. | A saved memory may remain even after the chat that prompted it is deleted. |
| Control | Deleting a conversation affects that conversation according to the product’s rules. | Memory may have its own controls for viewing, editing, disabling, or deleting entries. |
A product can have conversation history, a separate memory feature, both, or neither. Check the specific product’s settings and deletion rules rather than assuming that clearing a chat clears every stored copy or summary.
What does ChatGPT remember about me?
ChatGPT’s memory and reference features vary by account, plan, region, platform, and workspace. Depending on the experience available to you, it may use saved memories or refer to past chats; its help page also lists possible sources such as custom instructions, Library files, and connected apps. ChatGPT does not retain every detail from every conversation, and the information used for personalization can change as context changes. OpenAI: Memory FAQ
To inspect available controls, open Settings → Personalization → Memory. Depending on your account, you may be able to review a memory summary or saved items, correct or delete them, switch memory or reference controls off, or use Temporary Chat when you do not want personalization memory used or updated. Labels and options can differ. You can also ask ChatGPT what it remembers or tell it not to use a particular fact, but asking it not to mention something does not delete the underlying chat, file, or other source.
How do I turn off or delete AI memory?
Turning off a memory feature generally controls future use or updates; it does not necessarily erase history or every source from which information could be retrieved. The exact steps depend on the product.

In ChatGPT, check Settings → Personalization → Memory for the controls available to your account. To remove information from personalization, OpenAI says you may need to remove it from each relevant location, potentially including saved memories, chats, Library files, and connected apps. Deleting the original chat alone may not delete a separate saved memory derived from it; turning memory off does not delete past chats. OpenAI also says deletion or memory updates can take time to propagate and that deleted-memory logs may be retained for up to 30 days for safety and debugging. OpenAI: Memory FAQ
Claude
Claude’s consumer controls are separate from developer memory-store controls. Where available, users can view or edit memory, ask Claude in a chat to remember, change, or forget information, and switch memory or past-chat search through settings. Team and Enterprise users may also be subject to organization-level settings; an individual cannot necessarily override them. Check the current account or workspace settings for deletion and retention behavior. Anthropic: Understanding Claude’s memory
A practical removal checklist
- Ask the assistant what it currently remembers, then review any summary or individual entries the product exposes.
- Correct or delete inaccurate or unwanted entries using the product’s memory controls.
- Check whether memory and chat-history reference are controlled by separate switches.
- If you want information removed, check the saved memory and the original chat, file, or connected source; disabling a feature may only stop future use or updates.
- For a one-off sensitive task, use a temporary or no-memory mode if available, and consult the product’s retention terms.
How developers should control agent memory
For developers, the key questions are what can be written, where it is stored, when it is retrieved, and who can inspect or change it. The right design depends on the framework and the application’s privacy and reliability needs.
Choose what the agent may write
OpenAI’s sandbox SDK uses post-run extraction and consolidation to write memory into files such as MEMORY.md and memory_summary.md; generation can be configured. Decide whether the application needs a transcript, reusable notes, or both, rather than treating them as interchangeable. OpenAI Agents SDK: Sandbox memory and Sessions
Set permissions deliberately
Anthropic’s managed memory stores support read_only and read_write access and attach at session creation. OpenAI’s SDK also supports read-only memory and generate-only modes. Read-only access is often a safer fit for fixed reference material; writable memory is useful only when the agent needs to update persistent information.

Make changes inspectable and recoverable
Anthropic documents direct API or Console editing of managed stores and immutable memory versions for audit and point-in-time recovery. Its documentation states: “Every change to a memory creates an immutable memory version, giving you an audit trail and point-in-time recovery for everything the agent writes.” This guarantee applies to Anthropic’s managed memory stores, not to memory systems generally. Anthropic: Give Claude persistent memory
Protect memory from untrusted writes
Untrusted prompts, fetched pages, or third-party tool results can introduce malicious instructions into writable memory. A later session may then treat that content as trusted context. Validate what is written, limit write access, and treat retrieved content as data rather than privileged instructions. Anthropic specifically warns about this prompt-injection risk in its managed-memory guidance. Anthropic: Give Claude persistent memory
Define persistence and lifecycle
Memory files persist between runs only if the configured workspace, snapshot, or storage is preserved. A fresh empty sandbox may not contain earlier memory. Specify retention, deletion, backups, and isolation boundaries for the actual implementation rather than assuming that a memory file will always follow an agent. OpenAI Agents SDK: Sandbox memory
How to compare memory designs
Product names alone do not tell you whether one memory system is better. Compare the underlying behavior and controls that matter for your use case.
| Axis | Questions to ask |
|---|---|
| Scope | Is memory limited to a task, project, user, agent, or shared workspace? |
| Representation | Is it a transcript, summary, set of files, structured records, or searchable history? |
| Write policy | What is stored automatically, what requires explicit instruction, and can the agent update or forget items? |
| Retrieval | Is context always supplied, summarized progressively, or retrieved when relevant? |
| User visibility | Can a user inspect, correct, export, or delete individual memories? |
| Permissions and security | Can the agent write? Can untrusted content reach the store? Are changes versioned or audited? |
| Retention and portability | What persists between sessions, what happens when a source conversation is deleted, and can data be exported or moved? |
| Evidence of utility | Were performance claims measured on tasks and baselines relevant to your use case? |
Does memory improve AI agents?
Memory can reduce the need to repeat context, but a performance result from one method is not a guarantee for every system. A 2026 paper by the MemCon authors reports task success up to 15.2 points higher and token consumption 5–20% lower for its adaptive memory-management approach across six benchmarks, three agent frameworks, and three model backbones. Those are study-specific results, not a universal industry statistic or a promised product benefit. MemCon paper (2026)
There is no single standard memory schema or controlled product-to-product comparison established by these cited product documents and study. Official documentation describes particular implementations and controls, so comparisons should stay tied to the actual features and tasks being evaluated.
