OpenAI’s Enterprise AI Report Reveals 8x Usage Growth and Massive Productivity Gains

Summary: OpenAI’s first comprehensive enterprise AI report reveals dramatic adoption acceleration: ChatGPT Enterprise messages increased 8x year-over-year, while organizations consume 320x more reasoning tokens for complex problem-solving. Workers save 40-60 minutes daily, with 75% reporting improved speed or quality. Custom GPT usage jumped 19x, now handling 20% of enterprise messages. Technology, healthcare, and manufacturing lead sector growth, while Australia, Brazil, Netherlands, and France show 140%+ year-over-year expansion. However, a growing divide separates “frontier” workers (95th percentile) who send 6x more messages from median users, and reasoning token costs raise sustainability questions.

ChatGPT Enterprise usage surged 8x over the past year, with workers reporting 40-60 minutes saved daily and organizations consuming 320 times more reasoning tokens signaling that enterprise AI has moved from experimentation to systematic integration. OpenAI’s inaugural “State of Enterprise AI” report, released December 8, 2025, draws on real-world usage data from enterprise customers and a survey of 9,000 workers across nearly 100 organizations to document how AI is reshaping professional work.

Key Findings at a Glance

The report arrives at a pivotal moment: OpenAI serves over 800 million weekly ChatGPT users, and this consumer familiarity is creating a powerful flywheel that accelerates enterprise adoption. Unlike past general-purpose technologies that took decades to translate underlying capabilities into scaled business value, enterprise AI appears to be entering its productivity phase remarkably fast.

The Numbers Behind the Surge

Three metrics capture the magnitude of enterprise AI integration over the past 12 months:

• 8x increase in weekly ChatGPT Enterprise messages, with average workers sending 30% more messages individually
• 320x growth in reasoning token consumption via API, indicating organizations are deploying AI for complex, multi-step problem-solving
• 19x jump in structured workflow usage (Projects and Custom GPTs), now accounting for 20% of all enterprise messages

Custom GPTs specialized assistants companies build to codify institutional knowledge exemplify this depth of integration. Digital bank BBVA regularly deploys over 4,000 custom GPTs across its operations, transforming AI from a general assistant into a platform for automating specific business processes.

How Workers Are Saving Time with Enterprise AI

Across surveyed enterprises, 75% of workers report that AI has improved either the speed or quality of their work output. Time savings average 40-60 minutes per day for typical users, while heavy users report reclaiming more than 10 hours weekly. These gains compound as users engage with more advanced features and apply AI across diverse tasks.

Real-World Productivity by Department

Different functions realize value in distinct ways:

Beyond accelerating existing workflows, AI is expanding what workers can accomplish. Coding-related messages increased 36% among workers outside technical functions (engineering, IT, research), and 75% of users report completing tasks they previously couldn’t perform from data analysis to prototyping to technical documentation.

The Growing AI Adoption Divide

OpenAI’s data reveals a widening performance gap between AI “frontier” users and the median. Frontier workers at the 95th percentile send 6x more messages than median employees and engage more intensively with advanced capabilities like data analysis, reasoning models, and search. Similarly, frontier firms send 2x more messages per seat and show deeper cross-team integration.

This divide matters because time savings increase with consumption heavier users extract proportionally more value. Brad Lightcap, OpenAI’s COO, explained that frontier organizations treat AI “almost more like an operating system” rather than just software, fundamentally re-platforming company operations.

Custom GPTs and Structured Workflows

The 19x growth in Projects and Custom GPTs signals a shift from casual querying to integrated, repeatable processes. Custom GPTs enable companies to embed domain expertise, compliance rules, and brand guidelines into AI assistants that multiple teams can use consistently. This structured approach helps organizations scale AI adoption while maintaining quality and governance.

Industries Leading Enterprise AI Adoption

Technology, healthcare, and manufacturing are experiencing the fastest growth rates, while professional services, finance, and technology operate at the largest absolute scale. The breadth of adoption suggests AI is delivering value across fundamentally different business models and operational contexts.

Geographically, Australia, Brazil, Netherlands, and France each exceeded 140% year-over-year customer growth. International API customer expansion topped 70% over six months, with Japan hosting the largest corporate API customer base outside the United States. These patterns indicate enterprise AI adoption is a global phenomenon rather than a Silicon Valley trend.

Beyond Speed: AI Enabling New Capabilities

The report challenges the assumption that AI merely automates existing work. While efficiency gains are real, one study found ChatGPT users completed business writing tasks in 17 minutes versus 27 minutes without AI, a 59% productivity improvement  the more profound impact may be democratizing capabilities.

When non-technical workers can write functional code, perform statistical analysis, or generate marketing assets previously requiring specialists, AI reduces the gap between intent and execution. This capability expansion could reshape team structures, skill requirements, and career paths across industries.

What’s Driving the Enterprise Shift

Consumer adoption creates a unique advantage for ChatGPT’s enterprise expansion. With 800 million weekly users already familiar with the interface and capabilities, enterprise rollouts face less friction, pilots are shorter and ROI materializes faster. OpenAI’s enterprise offerings (ChatGPT Enterprise, Team, and Edu) now serve 1.5 million users, up from 600,000 in April 2024, and are deployed across 92% of Fortune 500 companies.

The Infrastructure Behind the Growth

OpenAI has committed $1.4 trillion to infrastructure investments over the coming years, making enterprise revenue growth essential to its business model. Organizations access GPT models either through Microsoft Azure or directly via OpenAI’s API, with API usage showing particularly strong growth 320x increase in reasoning tokens suggests systematic integration into products and services.

However, this growth raises sustainability questions. Reasoning tokens correlate with increased energy usage and cost, potentially creating budget pressures if organizations experiment heavily without optimizing for value. OpenAI has not yet disclosed typical enterprise budget allocations for AI or addressed long-term cost sustainability.

Challenges and Concerns

Despite positive headline metrics, enterprise AI adoption faces meaningful obstacles. The report notes that even highly active ChatGPT Enterprise users aren’t fully leveraging advanced tools like data analysis, reasoning, or search suggesting adoption requires deeper workflow integration and mindset shifts rather than just software deployment.

Brad Lightcap acknowledged this challenge: “There are firms that still very much see these systems as a piece of software… And then there are companies that are really starting to embrace it, almost more like an operating system”. Closing this gap requires organizational readiness, change management, and process redesign capabilities that don’t scale as quickly as model performance.

The 36% increase in coding messages from non-technical teams also raises security concerns. More “vibe coding” by workers without software engineering backgrounds could introduce vulnerabilities and bugs. OpenAI pointed to Aardvark, its agentic security researcher currently in private beta, as a potential solution for detecting exploits.

The Competitive Landscape

OpenAI’s enterprise push comes amid intensifying competition. According to Ramp’s AI Index, 36% of U.S. businesses subscribe to OpenAI tools compared to 14.3% for Anthropic, a significant lead, but one OpenAI must defend against multiple threats. Google’s Gemini poses a particular challenge to OpenAI’s consumer base, which still generates the majority of revenue, while Anthropic’s B2B focus and open-weight models target enterprise customers directly.

CEO Sam Altman’s internal “code red” memo about Google’s competitive threat, sent one week before this report’s release, underscores the stakes. The timing of the enterprise AI report appears designed to reframe OpenAI’s position as the enterprise leader just as competitive pressure mounts.

What This Means for Organizations

OpenAI releases new features or capabilities roughly every three days, making organizational readiness not model performance the primary constraint on AI value creation. The report functions as both a benchmark showing how leading enterprises deploy AI today and a roadmap for organizations still in early adoption stages.

The widening gap between frontier and median users suggests first-mover advantages may compound over time. Organizations that treat AI as infrastructure for re-platforming operations, rather than point solutions for specific tasks, appear positioned to capture disproportionate value. As Ronnie Chatterji, OpenAI’s chief economist, noted: “When you look at historically transformative technologies like the steam engine, it’s when firms adopt and scale these technologies that you really see the biggest economic benefits”.
