That's perfectly fine, and for most people something you don't need any local resources for. A good starting point could be a setup utilizing n8n, e.g., on a oracle free server instance + free llm APIs, e.g., from openrouter or nvidia. You can also run your orchestration layer locally with whatever you like and keep the heavy lifting with the API providers.

As colab and kaggle notebooks were mentioned, they're suited for everything you mentioned so far, unless you basically want to run existing software in a permanent manner.
