Updated our release of ClaudeSmalltalk today to better support the OpenAI codex models, and added xAI support. 
Any Pharo developer who would like to assist in altering the code base to support Pharo? 

In asking the various LLM models to explain for example the class 'FMSound' I found that xAI Grok 4.1 Fast gave the best answer as compared to OpenAI, Anthropic, and Qwen. It is significantly cheap too.
