Please add support for Google Gemini 3.8, 3.7 or 3.6. Currently 3.5-flash is the newest and its outdated. We've been building with Vapi now for nearly 3 years, averaging 60k mins/mo and have found google's gemini 3.5-flash to be the best all round LLM for complex multi-agent squads with large dyanmic prompts and complex workflows but it has some issues. Happy to explain the issues in more detail if needed.
