The information in this article is current as of August 2026. Notion AI plans, usage limits and supported models may change as the product is updated.
Notion AI officially introduced usage limits on August 3, 2026. Business and Enterprise plans now track both usage within a rolling six-hour window and total usage across the monthly billing cycle. When a workspace approaches its limit, certain AI features may be temporarily paused until earlier usage gradually expires, the next billing cycle begins, or the workspace switches to purchased Notion Credits.
A few days before the new system took effect, a Plus user on Reddit’s r/Notion community reported that their AI allowance was exhausted after sending only two messages using Kimi K3. However, the post was later deleted, making it impossible to verify the account’s previous usage, prompt length or actual deduction method. Plus already provides only a limited number of AI trial responses, so the exhausted allowance cannot be attributed entirely to Kimi K3.
These two cases involve different allowance systems, but they reflect the same broader change: Notion AI is moving away from a usage model that once felt nearly unlimited and invisible toward one that is measurable, restricted and potentially subject to additional charges.
How Do Notion AI Usage Limits Work? The August 3 Changes Explained
The Notion AI usage limits that took effect on August 3, 2026 primarily apply to Business and Enterprise workspaces.
The system checks both short-term usage and cumulative usage across the billing cycle, preventing a small number of accounts from consuming excessive computing resources within a short period.
This does not mean that every user receives a fixed, publicly disclosed number of messages.
Notion has not announced how many Agent requests each plan includes, how many images can be generated or how much allowance each model consumes. Actual usage may vary according to the task, input length, output length and selected model.
What Is the Difference Between the Six-Hour Rolling Window and the Monthly Allowance?
The six-hour allowance is calculated on a rolling basis. It does not reset completely at a fixed time.
For example, if a large task generates significant usage at 10:00 a.m., that usage will begin to leave the six-hour window after 4:00 p.m.
If AI continues to be used during that period, newer activity will also remain within the calculation. As a result, access may not be restored exactly six hours after the interface first displays a limitation.
The monthly allowance is calculated according to the workspace’s billing cycle.
If usage within the six-hour window has already fallen but the monthly allowance remains exhausted, some AI features may still be unavailable.
Users must then wait for the next billing cycle or, where enabled by an administrator, continue using the service through Notion Credits.
Which Notion AI Features May Be Restricted?
When usage approaches the limit, Notion Agent, page translation, image generation and certain Skills may be paused.
The restriction methods are not necessarily identical across all features. AI Meeting Notes, Custom Agents and Workers may also follow separate usage or billing rules.
Notion displays the current allowance status, warnings and estimated recovery time in the Usage dashboard.
Workspace administrators can review overall usage through workspace settings, while individual members can view usage information associated with their own accounts.
Can Notion Credits Be Used Immediately After the Allowance Runs Out?
A workspace that has purchased Notion Credits does not automatically allow every member to continue using AI beyond the included allowance.
An administrator must first enable the relevant setting that permits standard Notion AI usage exceeding the plan allowance to consume Credits.
If the workspace has not purchased Credits, or if the administrator has not enabled overage usage, users must wait for usage to expire from the rolling window or for the next billing cycle to begin.
Notion Credits were originally used primarily for additional computing features such as Custom Agents.
Under the new system, Credits can also serve as a continuation method when standard Notion AI usage exceeds the included allowance.
However, these uses continue to exist alongside one another. The Custom Agents billing system has not simply been transferred directly to ordinary Notion AI chat features.
Why Did a Plus User Run Out of AI Allowance After Only Two Messages? The Limited Trial Is the Main Reason
Since Notion revised its AI plans in May 2025, full Notion AI access has primarily been included with Business and Enterprise plans.
Free and Plus users receive only a limited number of trial responses.
The Plus subscription fee mainly covers features such as file uploads, collaboration, websites, charts and version history. It does not include unrestricted access to Notion AI.
Upgrading from Free to Plus also does not necessarily provide a new set of AI trial responses.
If an account has already used part of its trial allowance, the user may still see an allowance-exhausted message shortly after upgrading.
Notion Has Not Published a Fixed Number of Plus Trial Messages
Notion has not stated exactly how many AI responses are included in the Plus trial or whether all AI functions use the same deduction method.
Running out of allowance after two messages may indicate that the account had already consumed part of its trial allocation. It may also have been affected by prompt length, attached page content or output size.
A request that asks AI to search an entire workspace, read several documents and produce a long response will generally require more processing than a simple request to revise one sentence.
Is the Plus Plan Enough for Long-Term Notion AI Use?
If Notion AI is used only occasionally to test summaries, revise text or ask questions about a page, the limited Plus trial can help determine whether the features meet your needs.
If you intend to use Notion Agent, enterprise search, AI Meeting Notes or large-scale page organization every day, Plus is not a reliable long-term AI plan.
These workflows generally require a Business plan or above, along with an assessment of whether the workspace’s usage limits can support the actual workload.
Upgrading to Business does not mean that AI becomes completely unlimited.
After August 3, 2026, full Notion AI access remains subject to the rolling six-hour limit and monthly allowance management, although the available usage is significantly greater than the trial access offered to Free and Plus users.
Does Kimi K3 Consume More Notion AI Allowance? What Can Currently Be Confirmed
Kimi K3 is a reasoning model that requires substantial computing resources, but Notion has not published a formula showing how usage is calculated for each model.
In other words, K3’s technical characteristics and higher public API pricing can be confirmed, but it is not currently possible to calculate how much Notion AI allowance a single K3 response consumes.
The deduction ratio between K3 and other models is also unknown.
Kimi K3 Cannot Disable Reasoning Completely
Kimi K3 does not offer a fully non-reasoning mode. Users can only adjust the intensity of its reasoning through different reasoning effort settings.
This means that even when the final visible answer contains only a few paragraphs, the model may still generate additional reasoning tokens at the API level.
For complex tasks, the hidden reasoning process may be longer than the answer shown to the user, increasing the overall computing requirements.
K3’s public API output price is US$15 per million tokens, while K2.6 costs US$4 per million output tokens.
The difference in public pricing is substantial, but these figures belong to Moonshot’s API pricing and cannot be treated as Notion AI’s internal allowance-conversion standard.
Notion Has Not Disclosed How Kimi K3 Usage Is Converted into Allowance
The original Reddit poster stated that they had selected Kimi K3 within Notion.
However, Notion’s public documentation currently does not provide a complete listing for K3 or a conversion table comparing usage across different models.
It is therefore reasonable to infer that advanced reasoning models generally require more computing resources.
It would not be accurate, however, to claim that K3 always consumes the most allowance or that the two-message case was definitively caused by K3.
Actual usage may also be affected by:
- The length of the input documents
- Whether the AI searches the entire workspace
- The requested output length
- The number of tool calls
- The length of the conversation context
The model is only one of several variables.
Choosing a Model Also Means Choosing Resource Consumption
Users do not need to select the most powerful available model for every task.
Correcting spelling, rewriting sentences, organizing meeting highlights or adjusting formatting generally does not require prolonged reasoning.
Auto mode or a more efficient model will often be sufficient.
Advanced reasoning models are more appropriate when comparing multiple sources, handling complex conditions, planning large projects or performing multi-step analysis.
This allocation strategy cannot guarantee a fixed percentage of savings, but it can prevent simple work from consistently using a high-cost model.
How Can You Reduce Notion AI Usage? Four Adjustments You Can Make Immediately
Notion has not published an exact usage-conversion formula, but users can still reduce unnecessary consumption through task planning, model selection and conversation management.
Use Auto or an Efficient Model for Simple Tasks
For text polishing, summarization, formatting and straightforward questions, begin with Auto or a more efficient model.
These tasks do not usually require extensive reasoning. Selecting an advanced model may increase processing requirements without producing a meaningful difference in quality.
If Auto does not produce an acceptable result, switch models for that specific task instead of beginning every request with a high-level reasoning model.
Check the Usage Dashboard for Allowance and Recovery Information
Business and Enterprise users can review both the rolling six-hour usage and the monthly allowance.
When a feature is paused, first determine whether the short-term limit has been reached or whether the allowance for the entire billing cycle has been exhausted.
The two situations require different responses.
Usage within the six-hour window gradually expires over time. A monthly allowance generally requires waiting for the next billing cycle or using Notion Credits where the workspace permits it.
Keep Related Work in the Same Conversation
If the same task is divided across several new conversations, the AI may need to reread background material and interpret the requirements again.
Keep related work within the same conversation and clearly state the objective, output format, length and restrictions in the initial request.
This can reduce repeated explanations and unnecessary regeneration.
When working with many documents, avoid attaching the entire workspace. Include only the pages required to complete the task.
A shorter prompt is not necessarily more economical.
If insufficient information causes several rewrites, the total usage may exceed the cost of providing complete instructions once.
Confirm Administrator Settings Before Using Notion Credits
If a workspace intends to use Notion Credits after exceeding its included allowance, administrators should first confirm that the relevant permissions have been enabled.
They should also establish a spending limit and decide which members are permitted to consume Credits.
Without restrictions, members may begin using Credits automatically after the plan allowance is exhausted, leaving administrators to discover the additional cost only at the end of the month.
Administrators should regularly review Credits usage records to determine whether the majority of consumption comes from standard Notion AI, Custom Agents or other separately billed features.
Following the launch of Notion AI usage limits, one of the easiest mistakes is to treat every allowance issue as the same problem.
Business and Enterprise users are subject to the rolling six-hour window and monthly allowance. Plus users are dealing with a limited trial. The two systems should not be compared as though they operate under the same rules.
Kimi K3 does require more reasoning resources, and its public API output price is higher than K2.6. However, Notion has not explained how model costs are converted into its internal usage allowance.
The deleted Reddit example involving two messages lacks a complete usage history and should not be treated as a fixed rule that applies to every account.
The more practical response is to check the Usage dashboard, assign simple tasks to Auto or a more efficient model and reserve advanced reasoning models for genuinely complex work.
What has become clearer is the amount of usage remaining—not the complete method used to calculate its cost.
Frequently Asked Questions
No.
The six-hour allowance is calculated on a rolling basis. Earlier usage gradually leaves the calculation after more than six hours rather than resetting completely at a fixed time.
If the monthly allowance has been exhausted, users must still wait for the next billing cycle or use Notion Credits where permitted by the workspace.
The new Notion AI usage limits took effect on August 3, 2026 and primarily apply to Business and Enterprise workspaces.
The system tracks both usage within a rolling six-hour window and the monthly allowance. Certain AI features may be paused when usage approaches the limit.
The Plus plan includes only a limited Notion AI trial and does not provide full AI access.
The allowance may have been exhausted quickly because the account had previously consumed part of its trial responses, or because of the prompt length and scale of the task.
A two-message example alone is not enough to conclude that a specific model caused the allowance to run out.
Kimi K3 cannot completely disable its reasoning mode, and its public API output price is higher than K2.6, so it generally requires more computing resources.
However, Notion has not published its model-specific allowance-conversion formula. It is therefore impossible to confirm exactly how much Notion AI allowance one K3 response consumes.
Yes, but the workspace must first purchase Credits and an administrator must enable overage usage.
If the workspace has no Credits or the necessary permission has not been enabled, users must wait for usage to expire from the rolling six-hour window or for the next billing cycle to begin.
