How can I use it with Vapi already? I tried using it as a custom model. Provider: custom-llm Model: meta-llama/llama-4-scout-17b-16e-instruct Custom LLM URL: https://api.groq.com/openai/v1/chat/completions Then added the Groq API key in the Custom-LLM provider keys, didn't work for me. I tried using OpenRouter after, but I coulding pick the provider to be Groq. How did you pull it off @Pigeon ?
