ChatGPT hits 200 million active weekly users, but how many will admit using it?

On Thursday, OpenAI said that ChatGPT has attracted over 200 million weekly active users, according to a report from Axios, doubling the AI assistant's user base since November 2023. The company also revealed that 92 percent of Fortune 500 companies are now using its products, highlighting the growing adoption of generative AI tools in the corporate world.

The rapid growth in user numbers for ChatGPT (which is not a new phenomenon for OpenAI) suggests growing interest in—and perhaps reliance on— the AI-powered tool, despite frequent skepticism from some critics of the tech industry.

"Generative AI is a product with no mass-market utility—at least on the scale of truly revolutionary movements like the original cloud computing and smartphone booms," PR consultant and vocal OpenAI critic Ed Zitron blogged in July. "And it’s one that costs an eye-watering amount to build and run."

Despite this kind of skepticism (which raises legitimate questions about OpenAI's long-term viability), OpenAI claims that people are using ChatGPT and OpenAI's services in record numbers. One reason for the apparent dissonance is that ChatGPT users might not readily admit to using it due to organizational prohibitions against generative AI.

Wharton professor Ethan Mollick, who commonly explores novel applications of generative AI on social media, tweeted Thursday about this issue. "Big issue in organizations: They have put together elaborate rules for AI use focused on negative use cases," he wrote. "As a result, employees are too scared to talk about how they use AI, or to use corporate LLMs. They just become secret cyborgs, using their own AI & not sharing knowledge"

The new prohibition era

It's difficult to get hard numbers showing the number of companies with AI prohibitions in place, but a Cisco study released in January claimed that 27 percent of organizations in their study had banned generative AI use. Last August, ZDNet reported on a BlackBerry study that said 75 percent of businesses worldwide were "implementing or considering" plans to ban ChatGPT and other AI apps.

As an example, Ars Technica's parent company Condé Nast maintains a no-AI policy related to creating public-facing content with generative AI tools.

Prohibitions aren't the only issue complicating public admission of generative AI use. Social stigmas have been developing around generative AI technology that stem from job loss anxiety, potential environmental impact, privacy issues, IP and ethical issues, security concerns, fear of a repeat of cryptocurrency-like grifts, and a general wariness of Big Tech that some claim has been steadily rising over recent years.

Whether the current stigmas around generative AI use will break down over time remains to be seen, but for now, OpenAI's management is taking a victory lap. "People are using our tools now as a part of their daily lives, making a real difference in areas like healthcare and education," OpenAI CEO Sam Altman told Axios in a statement, "whether it's helping with routine tasks, solving hard problems, or unlocking creativity."

Not the only game in town

OpenAI also told Axios that usage of its AI language model APIs has doubled since the release of GPT-4o mini in July. The suggests software developers are increasingly integrating OpenAI's large language model (LLM) tech into their apps.

And OpenAI is not alone in the field. Companies like Microsoft (with Copilot, based on OpenAI's technology), Google (with Gemini), Meta (with Llama), and Anthropic (Claude) are all vying for market share, frequently updating their APIs and consumer-facing AI assistants to attract new users.

If the generative AI space is a market bubble primed to pop, as some have claimed, it is a very big and expensive one that is apparently still growing larger by the day.
