ChatGPT’s impressive growth as a consumer app continues as the chatbot is on track to hit 700 million weekly active users this week, the company says.

The app had earlier reached 500 million weekly active users as of the end of March, noted Nick Turley, OpenAI VP and head of ChatGPT’s app, in a post on X. He also said the app has grown 4x since last year.

“Every day, people and teams are learning, creating, and solving harder problems. Big week ahead. Grateful to the team for making ChatGPT more useful and delivering on our mission so everyone can benefit from AI,” he posted.

The app’s popularity increased after OpenAI launched an upgraded image-generation feature, powered by the GPT-4 model, in March. In early April, the company’s COO, Brad Lightcap, said that more than 130 million users had created over 700 million images in just a few days after the launch.

The company has also seen an increase in subscribers. Last week, Lightcap said that ChatGPT had 5 million paying business users, up from 3 million in June.

In a recent report, market intelligence firm Sensor Tower noted that users are using ChatGPT for more than 12 days a month on average, only behind Google and X. The report also said that in H1 2025, users spent an average of 16 minutes per day on the app.
