The maximum payload size for asynchronous AWS Lambda functions is now 256KB. Previously, the limit was 128KB. Lambda supports multiple invocation modes today. Now, you can pass larger payloads when a function is invoked asynchronously, allowing Lambda to operate more seamlessly with services like SNS that already support larger payloads. Read our documentation to learn more about the asynchronous invocation type. 

There is no additional cost associated with invoking Lambda functions with an increased payload size. This feature is available in all regions where Lambda is available. For more information on where AWS Lambda is available, see the AWS region table. Please visit our product page for more information about AWS Lambda or log in to the AWS Lambda console to get started.
