The community members are discussing how to integrate a router query engine into a chat engine. They have tried using an agent, but it did not work well. They also tried changing the condense prompt, which provided better results. However, the agent requires a lot of tuning, and the community members have tried both the OpenAI agent and the React agent, with limited success. The OpenAI agent did not work at all, while the React agent gave some good answers but did not send the right query to the router query engine when asking for more questions in a chat. Finally, the community members mention that the router retriever did not work very well either.
