LLM packages which one to choose?

I had a conversation, with ChatGPT, this friday, on a question related to org-mode and remote execution of source block.

I have been impressed by its capabilities, and I totally agree with you, it is an over enthusiastic flatterer.

I prefer to use claude-code, codex like terminal tools directly in emacs. This meets my most needs.
