## Common questions

### Can I switch NLP services while keeping existing Parlant config and data?

In 1.6 this was unsupported, but it was fixed in 1.7.0. Use the latest release.

### Do I need a separate Parlant client library to call the server?

Yes. Use pip install parlant-client for Python or npm install parlant-client for TypeScript; without it your app cannot create or control agents.

### Which environment variables should I set when using Ollama with Parlant?

Set OLLAMA_MODEL, OLLAMA_EMBEDDING_MODEL, and OLLAMA_API_TIMEOUT. These choose the models and wait time.

### Which local port is used for the example server playground?

Use the test playground on port 8800 on localhost. If it does not load, check that the server is running and that port is not blocked.

### What does production deployment of Parlant involve?

Production deployment requires changes beyond local setup. The guide covers Kubernetes with authentication, persistence, and scaling.
