LLMConfig

Large Language Model configuration.

Provider Types:

openai, anthropic, groq, mistral: Traditional LLM providers (require separate STT and TTS config)

xai_realtime: xAI Grok Realtime - Speech-to-Speech provider (STT and TTS are handled internally)

When using xai_realtime, the stt_config and tts_config fields are ignored as Grok handles the full voice pipeline.
