Hi everyone, I’m Raghav Hinduja Swiss based IT-Professional. I’m trying to use OpenSearch ML to deploy custom machine learning models but I’m stuck. I’m not sure how to upload or register a model, what formats are supported, or if any conversion is needed. I’m also confused about how to call the model for inference, which APIs to use, and best practices for testing and integration. Can anyone share a clear step-by-step workflow for using custom ML models in OpenSearch?
