Sam Altman, CEO of OpenAI, has praised Prafulla Dhariwal, a Pune native, for his pivotal role in the development of GPT-4o, the latest groundbreaking AI model introduced by OpenAI. Altman’s commendation came just two days after the debut of GPT-4o, with the ‘o’ standing for Omni.

Dhariwal, a research scientist at OpenAI, leads the Omni team and is credited as the mastermind behind GPT-4o. Altman took to social media platform X to acknowledge Dhariwal’s contributions, stating, “GPT-4o would not have happened without the vision, talent, conviction, and determination of @prafdhar over a long period of time. That (along with the work of many others) led to what I hope will turn out to be a revolution in how we use computers.”

Dhariwal highlighted the collaborative effort behind the model’s creation. “This launch was a huge org-wide effort, but I’d like to give a shout-out to a few of my awesome team members who made this magical model even possible!” he wrote on X.

Dhariwal, who humorously introduces himself on his website with, “My name sounds like truffle, but with a P,” has been with OpenAI since 2016. Starting as a research intern, he has climbed the ranks to become a research scientist, focusing on generative models and unsupervised learning.

His portfolio includes co-creating GPT-3, the text-to-image platform DALL-E 2, the music generator Jukebox, and the reversible generative model Glow & PPO.

In 2009, Prafulla Dhariwal won the National Talent Search Scholarship and a gold medal at the International Astronomy Olympiad. He later earned gold medals in the International Mathematical Olympiad (2012) and International Physics Olympiad (2013), and achieved top scores in various entrance exams. Dhariwal graduated from MIT in 2017 with a perfect GPA of 5.0/5.0 in Computer Science (Mathematics).
