OpenAI held its big unveiling earlier this week, showing off the much more human-sounding and emotional ChatGPT-4o model with a big push for its voice mode.

With Google following up on its I/O keynote, it looks like the technology giant isn't just looking to AI rivals. In fact, held a little AI screening of the event. Michael Chang, from Google DeepMind Gemini and the Project Astra team, shared a video showing the company's Gemini chatbot watching GPT-4o at work.

Taking on X, Chang said "Gemini and I also had the opportunity to see the @OpenAI live announcement of gpt4o using Project Astra!""

"Congratulations to the OpenAI team, super impressive work!

In the video, Gemini is performing a transcription of the GPT-4o reveal event, attributing the quotes to the correct speaker and providing audio commentary.

Chang asks Gemini to give him a summary of "what happened" as part of the demo, and Gemini refers to the OpenAI team by name, but also explains what was shown on stage.

At the point where GPT-4o works to solve algebraic equations, Gemini solves equations, and OpenAI's model works through steps. Gemini details the steps to solve and gives praise to the opponent for how it solved the equation. Impressive stuff.
