OpenAI released GPT-5 on August 7, 2025, positioning it as "OpenAI's smartest, fastest, most useful model yet, and a major step towards placing intelligence at the centre of every business."
The model "unites and exceeds OpenAI's prior breakthroughs in frontier intelligence, spanning 4o, OpenAI o-series reasoning, agents, and advanced math capabilities." OpenAI reports that "5 million paid users now use ChatGPT business products" with organisations including "BNY, California State University, Figma, Intercom, Lowe's, Morgan Stanley, SoftBank, T-Mobile, and more" already deploying AI across their workforces.
According to OpenAI, "GPT‑5 delivers leaps in accuracy, speed, reasoning, context recognition, structured thinking, and problem-solving." Sean Bruich, Senior Vice President of AI & Data at Amgen, stated: "based on our internal evaluation, GPT-5 has met that bar and is doing a better job navigating ambiguity where context matters. We are seeing promising early results from deploying GPT-5 across workflows at Amgen including increased accuracy and reliability, higher quality outputs and faster speeds compared to prior models."
The launch coincides with "nearly 700 million people using ChatGPT weekly," reflecting widespread AI adoption. OpenAI anticipates "early adoption to drive industry leadership on what's possible with AI powered by GPT‑5, leading to better decision-making, improved collaboration, and faster outcomes on high-stakes work for organisations."
GPT-5 is "starting to roll out to Team users today, with access for Enterprise and Edu coming next week" and is "now available in the OpenAI API today." Team, Enterprise, and Edu customers will receive access to "GPT‑5 Pro, a version with extended reasoning for even more reliable and detailed answers."
GPT-5 targets enterprise deployment across organisations like Amgen, BBVA, Lowe's, Uber, Moderna, and Salesforce, offering enhanced accuracy, reasoning capabilities, and agent performance for business workflows, decision-making, and high-stakes organisational work.
OpenAI's GPT-5 launch demonstrates significant enterprise market penetration with 5 million paid business users and 700 million weekly ChatGPT users. The model's enhanced capabilities and enterprise customer testimonials position it for expanded business adoption, targeting productivity improvements, collaboration enhancement, and competitive advantage through AI-powered workflows.
