# gpt-sovits

Helm chart for deploying gpt-sovits microservice.

## Install the chart

```console
cd GenAIInfra/helm-charts/common/
export MODELDIR=/mnt/opea-models
helm install gpt-sovits gpt-sovits --set global.modelUseHostPath=${MODELDIR}
```

The gpt-sovits service will download model `lj1995/GPT-SoVITS` which is about 2.8GB.

## Verify

To verify the installation, run the command `kubectl get pod` to make sure all pods are running.

Then run the command `kubectl port-forward svc/gpt-sovits 9880:9880` to expose the gpt-sovits service for access.

Open another terminal and run the following command to verify the service if working:
