ChatGPT use is exploding inside companies

OpenAI has released new data showing strong growth in enterprise use of its tools.

ChatGPT message volume has risen eightfold since November 2024, and many workers say they save up to an hour a day.

The update follows CEO Sam Altman’s recent warning to staff about rising competition from Google.

According to the Ramp AI Index, 36% of U.S. businesses using enterprise AI tools now choose ChatGPT Enterprise, compared with 14.3% using Anthropic.

Even so, most of OpenAI’s revenue still comes from consumers, a group that’s also being courted, with increasing success, by Google’s Gemini.

This comes as OpenAI commits $1.4 trillion to infrastructure over the next few years, making enterprise growth essential.

The report also shows companies are using AI more deeply.

Use of “reasoning tokens” has increased 320 times year-on-year, suggesting more complex workloads, though this also raises cost and energy concerns.

Custom GPTs are up 19x and now make up 20% of enterprise messages; BBVA alone uses more than 4,000 of them.

OpenAI says these tools save workers 40–60 minutes a day.

Enterprise use is rising quickly, but advanced features are still underused.
Custom GPTs are becoming a major part of corporate workflows.
Higher reasoning-token use shows deeper adoption but also brings cost and sustainability questions.

Employees also report that AI is helping them take on tasks they previously couldn’t, including technical work.

Coding-related messages from non-engineers rose by 36%.

OpenAI acknowledged potential risks and pointed to its security tool Aardvark as one option to identify vulnerabilities.

Despite higher usage, many businesses still aren’t using advanced features like data analysis and reasoning.

OpenAI says full adoption takes time and requires changes to workflows.

The report also shows a growing gap between “frontier” users and slower adopters.
