    Same issue in VSCode Codex extension, how come it is unfixed for so long? Always have to waste some tokens just to send a message to switch to a better model...

    It is still broken btw! How a trillion dollar company can produce such startupish slop? Your devs have access to best models in the world and this is their end product.... very underwhelming.
