| Quota reached | Behavior | 
| --- | --- | 
| Message length (15,000 characters) | The message box shows a character count, and you cannot submit the message until you shorten it. | 
| Request rate | Additional questions are throttled and return a rate limit error. Wait a moment, and then try again. | 
| Chat context | Responses no longer reflect the earliest turns in the chat. Provide the relevant context in your next message. | 

## Request a quota increase
<a name="manager-assistant-quotas-increase"></a>

The request rate is the only adjustable quota. Because it is governed by the Connect Customer agent assist `SendMessage` service quota, request an increase through AWS Support rather than in the Service Quotas console. The maximum message length and chat context quotas are fixed application quotas during preview, and cannot be increased.

## Regional differences

The request rate varies by AWS Region. The maximum message length and chat context behavior are the same in all Regions where manager assistant is available.
