OpenAI said July 31 that its artificial intelligence platform has more than one billion active users [1].

This milestone signals the rapid integration of generative AI into global daily life and suggests a shift toward mass-market dominance as the company expands its corporate footprint.

Along with the user milestone, the company said that more than two million businesses now use the platform [1]. The growth comes as OpenAI adjusts its pricing strategy to maintain a competitive edge in the AI cost race [3].

To accelerate adoption, OpenAI implemented an 80% price cut for its GPT-5.6 Luna models [3]. This pricing shift lowers the barrier for developers and enterprises to integrate high-level reasoning models into their own software products.

Under the new pricing structure, GPT-5.6 Luna costs $0.20 per million input tokens [3]. The cost for output tokens is now $1.20 per million [3].

While most reports confirm the platform has surpassed the billion-user mark [1], some sources indicate that weekly active users are nearing that threshold [1]. The platform continues to expand its global reach, becoming one of the fastest applications to reach this scale of adoption [2].

OpenAI has not provided a detailed breakdown of regional growth, or the specific ratio of free to paid subscribers within this user base. However, the focus on business adoption and token pricing suggests a strategic pivot toward the API and enterprise markets.

The combination of a massive user base and aggressive price reductions for GPT-5.6 Luna indicates that OpenAI is prioritizing market share over short-term margins. By slashing token costs, the company is attempting to lock in enterprise developers and create a network effect that makes it difficult for smaller competitors to attract a similar scale of users.
