April 2026: Key delivery was the Voxtral-4B-TTS-2603 SageMaker Deployment Example (text + multimodal) in aws-samples/sagemaker-genai-hosting-examples. Implemented end-to-end deployment of Voxtral-4B-TTS-2603 using vLLM-omni on SageMaker, including text generation and multimodal data flows. The work was merged via PR #184 from Christian-kam/kamwang-updates (commit c4deedc113bbfcf12647cbcf402f8220ffdafcdd). This provides a reusable hosting/deployment pattern for GenAI models on SageMaker and a concrete customer proof-of-concept, reducing time-to-value for customers evaluating multimodal inference on SageMaker.
