We will try to create a YouTube video for this. **Q: Where can we find the other strings to use different OPENAI_MODELs?** A: In the documentation, I have used ChatGPT 3.5 Turbo and GPT 4 models. You can view these APIs at [https://platform.openai.com/docs/models](https://platform.openai.com/docs/models) . **Q: So, I would switch the endpoint if I want to start fresh again without context, correct?** A: Yes, you should switch the endpoint. You can check the available endpoints at [this OpenAI link](https://platform.openai.com/docs/models/default-usage-policies-by-endpoint) . **Q: I see the document on GitHub.**** Are you planning on having an example on GitHub for us to download?** A: Yes, we will soon add this to our GitHub repo, but we cannot set a date for that. **Q: So, this can also allow me to create multiple assistants in the chat?** A: Yes, you can create multiple assistants in the chat. **Q: I just got caught up. Where do we get the file restaurant_menu.txt?** A: It is available in [this GitHub link](https://github.com/SyncfusionExamples/create-a-custom-chat-bot-with-openai-apis-blazor-and-maui-integration) . **Q: Do we face file ownership issues still?** A: No, we don’t face any file ownership issues. **Q: Can Markdown support be added to the chat?** A: Yes, you can add Markdown support. When we deserialize the JSON, we can add code accordingly to evaluate the Markdown. **Q: Can the search work with DB and or Excel?** A: Yes, the search will also work for DB and Excel. **Q: Can you recommend any particular vector store?** A: We don’t recommend a specific database, but any vector database should be compatible. **Q: Do you have a specific YouTube channel or videos with other tutorials?** A: Yes, we do.
