"""OpenAI Bot Implementation.
This module implements a chatbot using OpenAI's GPT-4 model for natural language
processing. It includes:
- Real-time audio/video interaction through Daily
- Animated robot avatar
- Text-to-speech using ElevenLabs
- Support for both English and Spanish
The bot runs as part of a pipeline that processes audio/video frames and manages
the conversation flow.
