The graph above is the Elo chart from the LMSys arena. See that number circled in red a foot above the rest? That’s the mysterious “im-also-a-good-gpt2-chatbot” model that’s been doing the rounds on Twitter.

It’s also the new OpenAI model: GPT-4o (“Omni”). As early users thought from interacting with the gpt2-chatbot models, it’s better than GPT-4. Well, way better. I bet no one thought it’d be 60 Elo points better than GPT-4 turbo, the previous best model in the world.¹

For comparison, look at the models from other companies — Gemini 1.5 Pro, Claude 3, and Llama 3–70B (4, 5, and 7 respectively) — all trying desperately to reach the performance level of a 1.5-year-old model (with recent updates but old nonetheless).
