The issue requests adding Claude as a new LLM option for the Xiao Ai speaker. Start by examining how existing LLMs (e.g., ChatGPT via openai.py) are integrated in the xiaogpt codebase. Identify the common interface or adapter pattern. Then implement a new module for Claude using Anthropic's API. Pay attention to any specific requirements mentioned in the comments of issue #242. Ensure the new integration follows the same configuration and error handling patterns.
