Top artificial intelligence that can write code and solve math problems keeps failing at basic spelling at the level of kindergarten. Google's recently upgraded AI summary feature (AI Overview) has once again become a target of ridicule in the tech community due to frequent elementary spelling mistakes. In a series of public tests, the AI not only failed to count the letters in a word but also misspelled "Google".

Failure to Count Letters Leads to Ridicule

According to user feedback, Google's AI summary shows extremely absurd performance when dealing with basic spelling. It claims that "poop" contains the letter r and misspells the last names of presidents as incorrect letter combinations. In response to public questions from the media, Google officially stated that large language models have long struggled with counting letters in words, and the team is currently working on fixing this specific elementary mistake.

Token Architecture Causes "Illiteracy"

Researchers point out that these spelling errors are determined by the limitations of the underlying Transformer architecture of large language models. When processing text, AI does not read individual letters as humans do, but instead splits the text into numerical representations called "tokens." Since the model can only recognize encoded representations of entire words or syllables, it cannot perceive the internal structure of words. Therefore, such spelling defects are almost impossible to completely eliminate within the current technical framework.
