Hi, I am new to VAPI, I have noticed that VAPI allows you to configure idle-message[] which are static responses in case user doesnt say anything. In our instance if prompt has requested user with some information to which they havent responded, we would like to play a custom no-input message and request for that information again (instead of playing a static message like, are you still there?) Is it possible to have vapi use LLM to play a more dynamic (contextual) idle message ?

@_jagz_ Hello and welcome to VAPI! I'm glad to hear you're exploring the capabilities of our Voice API. Yes, VAPI can indeed be configured to provide a more dynamic and contextual idle message. Instead of using static responses, you can leverage the LLM to generate a custom message that takes into account the context of the conversation and the information that was requested from the user. To implement this, you would need to set up a system where the LLM is triggered when the user does not respond. The LLM can then generate a message that references the specific information that was requested, prompting the user to provide the necessary response. For example, if the user was asked for their account number and did not respond, the LLM could generate a message like, "I noticed you haven't provided your account number yet. Could you please share it with me so we can proceed?" This approach ensures that the idle message is not only a reminder for the user to respond but also a helpful nudge that guides them towards providing the specific information needed to continue the interaction. If you need assistance setting this up or have any further questions, please feel free to ask!

@Vapi we are trying to exactly achieve that, In my understanding VAPI needs to let LLM know that user hasn't responded for it to generate such a response (even if I include that in the system prompt), but I am unable to figure out how to trigger that?

@_jagz_ To achieve a dynamic response when the user hasn't replied, you would need to set up a mechanism within VAPI that detects when there's no input from the user after a prompt. Once this no-input event is detected, VAPI should trigger the LLM to generate a contextual response. Here's a general outline of the steps you might take: 1. **Detect No-Input**: Configure your VAPI system to recognize when the user has not provided a response within a certain timeframe after a prompt. 2. **Trigger LLM**: Once a no-input situation is detected, trigger the LLM to generate a contextual message. This would involve sending the current conversation context to the LLM. 3. **Generate Message**: The LLM uses the provided context to create a relevant and dynamic message that prompts the user for the required information. 4. **Play Message**: The generated message is then played back to the user as the no-input response. To set this up, you would typically need to work with event handlers or callbacks within your VAPI application that can handle the no-input scenario. If you're unsure about how to configure these triggers and handlers, you may need to consult the VAPI documentation or reach out to the support team for more detailed guidance on implementing this feature. If you have access to the VAPI dashboard and the necessary permissions, you can navigate to the "Model" section and select "Custom LLM" to begin setting up the integration. If you need further assistance with the technical setup, please let me know, and I can provide more detailed instructions or direct you to the support team for additional help.

@Vapi - it would be great if you can direct me to the support team. I am able to do that with custom LLM but not able to do so when VAPI is in the mix

@_jagz_ Certainly! If you're experiencing difficulties integrating the Custom LLM with VAPI for dynamic no-input responses, the best course of action would be to reach out to the VAPI support team for specialized assistance. They will have the expertise and access to guide you through the process and troubleshoot any issues you're encountering. Please contact the VAPI support team for more information on this. They will be able to provide you with detailed instructions and support tailored to your specific setup and requirements.

no you have to pass idle messages before LLM cannot generate idle messages during the call.

actually there is a way to do that by spoofing a "user" message to do that that tells the LLM that user hasnt responded so "assistant" can generate idle message, but I couldnt find a way to insert a dummy message into the conversation through VAPI API which you would otherwise do directly via chat-completion API

yeah i undestand there is no way to dynamically generate or spoof the message as of now
