ChatGPT temporary chat memory works differently than it did before August 27, 2026. Temporary Chats still start without personalization by default, but you can now choose a personalized Temporary Chat that uses your existing memories, custom instructions and plugins. You can also save a Temporary Chat if you decide the conversation is worth keeping.
The important distinction is that a personalized Temporary Chat can read existing personalization without creating new memories while the conversation remains temporary. Saving the conversation changes that boundary because the Temporary Chat becomes a regular chat and begins following your normal account settings.
Does ChatGPT Temporary Chat use memory? Not by default. A non-personalized Temporary Chat does not use memory, custom instructions or plugins. If you choose personalization when starting the Temporary Chat, it can use your existing memories, custom instructions and plugins—but it does not create or update memories while the chat remains temporary.
What Changed With ChatGPT Temporary Chat in August 2026?
OpenAI announced new Temporary Chat controls on August 27, 2026. Before this change, the simplest way to describe Temporary Chat was as a conversation separated from normal memory and history. That description is now incomplete.
Temporary Chat now has two possible starting states:
The default. It does not use memory, custom instructions or plugins and does not create new memories.
Uses your existing memories, custom instructions and plugins while still avoiding new memory creation during the temporary conversation.
If you save the Temporary Chat, it becomes a regular chat and starts following your normal account-level settings.
This is why older advice saying that Temporary Chat can never use memory is now outdated. The answer depends on whether personalization was enabled when the Temporary Chat began.
OpenAI says personalization must be chosen when you start the Temporary Chat. You cannot switch a conversation from non-personalized to personalized, or the other way around, after that Temporary Chat has already begun.
Personalized vs Non-Personalized Temporary Chat
The easiest way to understand the new system is to separate what a Temporary Chat can use from what it can create.
| Feature | Non-Personalized Temporary Chat | Personalized Temporary Chat | Saved Chat |
|---|---|---|---|
| Uses existing memories | No | Yes | Follows account settings |
| Creates or updates memories while temporary | No | No | Follows regular-chat settings |
| Uses custom instructions | No | Yes | Follows account settings |
| Uses plugins | No | Yes | Normal availability and permissions apply |
| Appears in chat history | No | No | Yes |
| Used to improve OpenAI models while temporary | No | No | Follows your account data controls |
| Can change personalization after starting | No | No | Not applicable |
How to Start a Personalized Temporary Chat
The exact position of ChatGPT controls can vary between web, desktop and mobile versions, but the important part is to make the personalization choice before the Temporary Chat begins.
- Start a new chat. Open the option for creating a Temporary Chat.
- Review the personalization choice. Temporary Chats begin non-personalized by default.
- Turn personalization on if you want existing context used. This can allow the Temporary Chat to use existing memories, custom instructions and plugins.
- Start the conversation. Once the Temporary Chat begins, its personalization state cannot be changed for that conversation.
If you do not see the new option yet, avoid assuming your account is broken. Feature availability can vary by rollout, account, plan, workspace, administrator controls or ChatGPT surface.

Can a Personalized Temporary Chat Create New Memories?
No— not while the conversation remains temporary.
A personalized Temporary Chat can reference memories that already exist in your account, but OpenAI says it will not create or update memories from the unsaved Temporary Chat.
This distinction matters because “uses memory” and “creates memory” are two different behaviors:
- Using memory means ChatGPT can refer to information already stored for personalization.
- Creating memory means information from the current conversation is added or updated for future personalization.
A personalized Temporary Chat can do the first while remaining blocked from the second.
Temporary Chat rule: personalized can read existing memories; temporary does not create new memories; saving converts the conversation into a regular chat.

Does Temporary Chat Use Custom Instructions and Plugins?
Under the current system, only personalized Temporary Chats use your custom instructions and plugins. Non-personalized Temporary Chats do not.
Custom instructions
If personalization is enabled before the Temporary Chat begins, your existing custom instructions can influence the responses in that conversation.
If you want the Temporary Chat to behave more like a blank-slate session, use the non-personalized option instead.
Plugins
OpenAI also says plugins are available in personalized Temporary Chats. Actual plugin availability can still depend on the plugin, your plan, workspace permissions, connected services and administrator controls.
If a plugin, GPT action or other connected third-party service receives information from the conversation, that third party may have its own privacy and retention policy. Temporary Chat does not override an external service’s data practices.
Can You Save a Temporary Chat?
Yes. One of the biggest August 2026 changes is the ability to save a Temporary Chat when the conversation becomes useful enough to keep.
But saving is more significant than simply placing a bookmark on the conversation.
Saving converts the Temporary Chat into a regular ChatGPT conversation.
After that conversion:
- the conversation appears in your chat history;
- it follows your normal account-level personalization settings;
- your memory settings can affect how the saved conversation is used later;
- your model-improvement preference applies as it would to a normal chat; and
- normal account and workspace restrictions still apply.
What happens if you save a non-personalized Temporary Chat?
The same basic conversion happens. The conversation becomes a regular chat and starts following your account’s normal settings from that point forward.
For example, OpenAI says that if memory is enabled, a saved conversation can become part of your chat history that may be referenced for future personalized responses.
Ask yourself whether you are comfortable moving the conversation from Temporary Chat rules into your normal chat history and account settings. If the reason you chose Temporary Chat was specifically to keep the conversation out of your regular history, saving changes that.
Can you find a saved Temporary Chat later?
Once saved, it is a regular conversation. If you need to locate it later, our guide explains how to search ChatGPT history and find old chats.
Does Temporary Chat Appear in History or Get Used for Training?
Chat history
An unsaved Temporary Chat does not appear in your normal chat history. If you save it, it becomes a regular chat and appears there.
Model improvement
OpenAI says a Temporary Chat is not used to improve its models while it remains temporary.
If you save the chat, it becomes a normal conversation and follows the model-improvement preference configured for your account.
Data retention
Temporary does not necessarily mean the data disappears immediately after you close the conversation. OpenAI says it may keep a copy of an unsaved Temporary Chat for up to 30 days for safety purposes.
That is an important privacy distinction: a Temporary Chat is excluded from normal history and model improvement while temporary, but it should not be described as an instant-deletion or zero-retention mode.
Old Temporary Chat Advice vs the Current Rules
If you are reading an older guide or watching an older tutorial, these are the differences most likely to cause confusion.
| Older simplified advice | Current Temporary Chat behavior |
|---|---|
| Temporary Chat never uses memory. | A personalized Temporary Chat can use existing memories. |
| Temporary Chat is always a blank-slate conversation. | Non-personalized is the blank-slate option; personalized can use existing context. |
| Temporary Chat cannot use custom instructions. | Personalized Temporary Chats can use them. |
| Plugins are unavailable in Temporary Chat. | Personalized Temporary Chats can use plugins. |
| You cannot save a Temporary Chat. | You can now save it and convert it into a regular conversation. |
| Saving merely keeps a copy of the temporary conversation. | Saving changes the conversation into a regular chat governed by normal account settings. |
Which Chat Mode Should You Use?
The right choice depends on what you want ChatGPT to know during the conversation and what you want to happen afterward.
| Your goal | Best starting option | Why |
|---|---|---|
| You want a one-off conversation without normal personalization. | Non-personalized Temporary Chat | It does not use memory, custom instructions or plugins. |
| You want a one-off conversation but still want ChatGPT to understand your usual preferences. | Personalized Temporary Chat | It can use existing context without creating new memories while temporary. |
| You expect to return to the conversation repeatedly. | Regular Chat | You avoid starting temporary and then converting it later. |
| You started temporarily but realize the conversation is valuable. | Save the Temporary Chat | It becomes a regular conversation you can find in history. |
The Designs24hr TEMP Decision Framework
Use these four questions before choosing your chat mode:
TTemporary purpose: Is this genuinely a one-off conversation?
EExisting context: Would your existing memories or custom instructions improve the answer?
MMemory boundary: Do you specifically want the current conversation excluded from creating new memory while it remains temporary?
PPreserve later: Is there a realistic chance you will want this conversation in normal chat history later?
If you answer yes to existing context but still want a temporary conversation, personalized Temporary Chat is the logical fit. If you want as little normal personalization as possible, choose non-personalized Temporary Chat. If you already know the conversation needs continuity, starting with a regular chat may be simpler.
Is ChatGPT Temporary Chat Completely Private?
It is safer to describe Temporary Chat as a conversation with different history, memory and model-improvement rules rather than calling it completely private.
There are several boundaries worth understanding.
1. OpenAI may retain a copy temporarily
OpenAI says it may retain an unsaved Temporary Chat for up to 30 days for safety purposes.
2. Limited prior context may still be used for safety
OpenAI’s current Temporary Chat FAQ says information from previous conversations may still be used in limited circumstances for safety and security purposes. Turning off personalization does not necessarily disable every safety system that uses relevant context.
3. Third-party services have their own rules
If a GPT action, plugin or connected service sends data to another provider, that provider’s privacy policy governs the information it receives. It may retain information longer than OpenAI keeps the Temporary Chat.
4. Saving intentionally changes the boundary
Once you save the conversation, it is no longer a Temporary Chat. It becomes a regular chat and follows your normal account-level personalization and data-control settings.
Use Temporary Chat when its reduced history and memory behavior matches your goal, but do not use it as a substitute for deciding whether highly sensitive information should be entered into an AI service in the first place.

Before You Save a Temporary Chat: 5-Point Checklist
- Re-read the conversation. Check whether it contains information you deliberately wanted kept outside normal chat history.
- Review memory settings. A saved chat starts following your normal personalization rules.
- Review model-improvement controls. The saved conversation follows your account’s normal preference rather than Temporary Chat’s no-training rule.
- Consider connected services. Information already sent to third-party tools remains subject to those services’ policies.
- Save only if future access is genuinely useful. Otherwise, leaving the conversation temporary preserves the reason you chose Temporary Chat in the first place.
ChatGPT Temporary Chat Memory FAQs
Does ChatGPT Temporary Chat use memory?
Not by default. Non-personalized Temporary Chats do not use memory. A personalized Temporary Chat can use your existing memories, but it does not create or update memories while it remains temporary.
Does Temporary Chat remember previous conversations?
A personalized Temporary Chat can use existing memories associated with your account. A non-personalized Temporary Chat does not use them. OpenAI also notes that limited information from prior conversations may still be used for safety and security purposes.

No. OpenAI says you choose whether the Temporary Chat is personalized when it begins. The setting cannot be changed after the conversation starts.
Does Temporary Chat use custom instructions?
Only a personalized Temporary Chat uses your custom instructions under the current system. A non-personalized Temporary Chat does not.
Can you use plugins in Temporary Chat?
Yes, in a personalized Temporary Chat. Plugin availability can still depend on your account, workspace, permissions, plan and the individual plugin.
Can you save a ChatGPT Temporary Chat?

How long does OpenAI keep Temporary Chats?
OpenAI says it may keep a copy for up to 30 days for safety purposes, even though an unsaved Temporary Chat does not appear in your normal chat history.
Is Temporary Chat the same as incognito or private browsing?
No. Temporary Chat changes ChatGPT’s history, personalization, memory and model-improvement behavior, but OpenAI may still retain a copy for safety, limited safety systems may use prior context, and third-party services can have separate data policies.
Final Takeaway
ChatGPT Temporary Chat is no longer simply “memory off.” Since August 27, 2026, you can choose between a non-personalized Temporary Chat and a personalized Temporary Chat that uses your existing memories, custom instructions and plugins.
The key boundary is simple: personalized Temporary Chat can use existing context, but an unsaved Temporary Chat does not create new memories and does not enter your normal chat history. If you save it, it becomes a regular conversation and starts following your normal account settings.
For most people, the best approach is to choose non-personalized Temporary Chat when they want a clean one-off session, personalized Temporary Chat when existing context would improve a temporary conversation, and regular ChatGPT when they already know the conversation should remain part of their ongoing history.
Feature interfaces, eligibility and account controls can change. This guide reflects OpenAI’s published Temporary Chat behavior checked September 2, 2026.
Save or share it with someone who still thinks Temporary Chat can never use memory. The August 2026 update changed that rule.
