GPT-5 Now Powers Enterprise Tools Across Slack, Google Drive and SharePoint

OpenAI announced that over 1 million business customers now directly use its products—making it the fastest-growing enterprise platform ever. This milestone includes companies paying for ChatGPT for Work and organizations using OpenAI’s developer APIs. Industry leaders like Amgen, T-Mobile, Target, Cisco, Morgan Stanley and Thermo Fisher Scientific have already adopted OpenAI’s tools to transform customer experience, streamline workflows and embed intelligence throughout operations.

The company, as noted in openai.com, credits its rapid enterprise expansion to the massive consumer adoption of ChatGPT, which now reaches 800 million weekly users. That familiarity has driven fast onboarding and shorter pilot phases for corporate clients. Within just two months, ChatGPT for Work usage grew 40%, surpassing 7 million seats, while ChatGPT Enterprise subscriptions increased ninefold year-over-year. OpenAI’s broad integration strategy is also accelerating adoption: companies can now use OpenAI models across collaboration tools like Slack, SharePoint, and Google Drive, with GPT-5 optimized for reasoning and data citations.

To support its skyrocketing enterprise growth, OpenAI rolled out new tools and integrations. Its Codex model—for code generation and automation—saw usage jump 10x since August, cutting engineering review times at Cisco by 50%. AgentKit allows companies to create and deploy enterprise-grade AI agents in days instead of months, with firms like Carlyle Group reporting 50% faster development and 30% improved accuracy. Meanwhile, new multimodal capabilities like Sora 2 for video, Image Generation APIs, and Realtime APIs for voice expand creative and operational possibilities across sectors.

OpenAI’s growing influence is reflected in measurable ROI: according to a Wharton study, 75% of enterprises see positive returns from AI, with fewer than 5% reporting losses. Companies like Indeed, Lowe’s, and Intercom have reported double-digit performance gains using OpenAI models. Looking ahead, OpenAI is positioning itself as the “operating system for work,” enabling businesses to build custom agentic workflows, integrate into popular platforms like Shopify, Etsy, and Salesforce, and transform how global industries operate.
