MLX AI Model selection Not Working

when I

Download one of the available MLX models to use on my Mac. It downloads & when I hit Start MLX, it does nothing. When I try to run an operation, it wants an API key for OpenAI. Is there no setting to select which model to use anymore? If I have three different API keys for Anthropic, Gemini, & OpenAI, how do I select the one I want to use at that moment in MLX? It's defaulting automatically & the MLX feature isn't working. Is there a fix? Somebody figured it out? I'm currently updated
