When NOT to use Langchain-Chatchat
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- If you are looking for a cloud-based solution that does not require local deployment and management.
- When your project specifically requires a different set of language models that are not supported by Langchain-Chatchat, such as models that are not listed in its documentation.
- If your use case does not benefit from the integration of RAG and Agent functionalities, and you are looking for a simpler chatbot solution.
- When you need a solution that is tightly integrated with a specific cloud provider's services, as Langchain-Chatchat is designed for local deployment and may not offer the same level of integration.
