### Product Version

- [ ] Amazon SageMaker Studio Classic
- [ ] Amazon SageMaker Studio
- [x] It is not related to SageMaker Studio

### Product Category

Inference and Endpoints

### Description

Serverless Inference is an excellent offering for workloads with intermittent or unpredictable traffic, thanks to its automatic scaling and pay-per-request pricing model. However, the lack of GPU variations currently limits its applicability for ML use cases that benefit from GPUs and CUDA acceleration.

### Other Details

_No response_

The issue names Amazon SageMaker Serverless Inference but provides no repository files, tests, or implementation entry point. Start by reviewing the Serverless Inference product area and determine the requirements for GPU and CUDA variants; done would require a concrete product decision or implementation scope for that support.
