Grok 4.5

Grok 4.5 is xAI's chat model, available here through Lithovas's unified API. It answers questions, writes, reasons, and calls tools in a conversation. It accepts a standard OpenAI-style messages array and streams a reply. Requests run server-side with your Lithovas credit balance, so you get xAI quality without managing a separate xAI account or key.
