In August 2026, OpenAI reached over one billion weekly active users and two million enterprise customers. To compete with Anthropic and Chinese laboratories, the company implemented price reductions across the GPT-5.6 family. While Anthropic maintains a larger market share, Ramp data indicates OpenAI is seeing faster enterprise spending growth, rising 82% quarter-over-quarter. OpenAI has expanded its ecosystem with a macOS plugin for Apple Messages, WebMCP support for autonomous desktop tasks, and simultaneous multi-account integration for Google services. Recent feature updates include the launch of GPT-Live and a temporary chat mode. This privacy-focused feature allows users to interact without the system accessing previous chats or using session data to update long-term memory. To ensure security, OpenAI retains copies of these dialogues for a maximum of 30 days before permanent deletion. Additionally, the platform introduced ‘Deep Research’, a tool that enables the collection and analysis of data from multiple web sources simultaneously, alongside expanded file and PDF analysis capabilities. On August 31, 2026, OpenAI experienced a global service disruption impacting the ChatGPT Work module, though backend developer infrastructure remained operational. In the defense sector, the Pentagon integrated ‘ChatGPT Mil’ into its GenAI.mil platform for unclassified logistics and administration tasks, following the exclusion of Anthropic’s Claude due to supply-chain risk designations. OpenAI’s advertising arm, ChatGPT Ads, reached an annualized revenue run rate of approximately $1 billion in less than 200 days. The service has expanded to more than 40 countries, including 31 European markets. Advertisements are targeted toward Free and Go subscription users, while Plus, Pro, and Enterprise tiers remain ad-free. OpenAI has introduced a self-service Ads Manager to support small and medium-sized businesses. In September 2026, OpenAI updated ChatGPT Voice, allowing Pro subscribers to access GPT-5.6 Sol and GPT-6 Astra.
