When NOT to use langserve
- When you prefer using frameworks or tools that are not built around Python's ecosystem and require languages like JavaScript or Java.
- If your project specifically requires a non-FastAPI backend for serving models because of specific performance criteria, constraints, or compatibility issues with FastAPI.

- Tags unique to dialog: api, chatgpt, nlp, nltk.
- Also covers LLM Frameworks.
- dialog ships Docker support for self-hosted deployment.
- Use dialog when you need to deploy a Retrieval-Augmented Generation (RAG) model without deep knowledge or experience with API development.
When NOT to use dialog
- Do not use dialog if your project requires customization beyond the provided structure, as it is based on a predefined framework in [dialog-lib](https://github.com/talkdai/dialog-lib).
- If your deployment environment does not support or require Docker, Dialog may not be suitable since its setup relies heavily on Docker and Docker Compose.
