-        Although training is free for all custom generative and custom template models, creating the training dataset for all models requires running the Layout model on the training documents. Customers are responsible for this cost.

         Custom generative models also rely on the auto label feature to speed up the generation of the labeled dataset. There's a cost associated with this action. While the build operation for template and generative models is free, creating the labeled dataset can result in some minimal costs.
 
-        Custom neural models have a limit on the number of models/the amount of time that models can be trained for free. The first 10 hours of training are free. If training a single model for longer than 10 hours or training multiple models that exceed the 10 hour limit, you need to enable paid training by setting a training budget. See [training a custom neural model](concept-custom-neural.md) for details. 
+        For `v4.0 2024-07-31-preview`, custom neural models can be trained for free for a **maximum of 10 hours**. Whether you are training a single model for the 10 hours, or training multiple models for the total of 10 hours, you won't be charged for the first 10 hours. After using up the free 10 hours, you will be **automatically charged by the extra training hour**. This new paid training feature enables training models for an extended duration to process larger documents. For more information on this paid training feature, check [custom neural model billing section](concept-custom-neural.md#Billing).
         
-        For v3.0 or v3.1 models the paid training tier only applies to added models, the training time per model isn't configurable.
+        For `v3.0 2022-08-31` or `v3.1 2023-07-31`, custom neural models can be trained for free for a maximum of 20 training sessions, with each session capped at 30 minutes of training duration. Once you use up all of the 20 training sessions, you can submit Azure support ticket to increase the training session limit. For increasing the limit, 2 training sessions will considered as 1 training hour. For more information on ways to increase the limit, check [custom neural model billing section](concept-custom-neural.md#Billing). **Note that for `v3.0` and `v3.1`, paid training feature is unavailable. Paid training feature for custom neural model is only available on `v4.0`.**
