NVIDIA Triton Inference Server is the best choice for deploying multiple models from different frameworks (TensorFlow, PyTorch, ONNX) in production. Triton provides a unified platform for serving models, supporting diverse frameworks with high performance on NVIDIA GPUs via features like dynamic batching and multi-model management. Option A (Clara Deploy SDK) is healthcare-specific. Option B (TensorRT) optimizes inference but isn't a full serving solution. Option C (DeepOps) aids deployment automation, not model serving. NVIDIA's Triton documentation emphasizes its versatility and efficiency for production inference across frameworks.
