GPT-5.2 still can't solve the infamous strawberry question despite billions in AI investment
OpenAI's GPT-5.2, released in December 2025, continues to incorrectly count two r's in the word strawberry when there are actually three. The error stems from the model's tokenization process, which splits the word into st-raw-berry tokens. While other AI models like Claude, Gemini, and Perplexity answer correctly, ChatGPT's tokenized input/output design creates persistent limitations in basic letter counting tasks that a seven-year-old could solve.
