OpenAI's GPT-4o Was Tested Under the Alias 'im-also-a-good-gpt2-chatbot'

OpenAI's GPT-4o was tested on LMSYS Chatbot Arena under the anonymous label im-also-a-good-gpt2-chatbot before the model was publicly announced. The alias was not a separate product, but one of several names used to evaluate GPT-4o ahead of its May 13, 2024 launch.
