OpenAI Expands Free Access to Powerful GPT-5.6 Models

conversations powered by GPT-5.6 Luna, its fastest and most cost-efficient model. The rollout also introduces a new "Think" button, allowing users to invoke deeper reasoning for more complex questions without paying for a premium subscription.

Meanwhile, Plus and Pro subscribers are getting an improved version of GPT-5.6 Sol, OpenAI's flagship reasoning model. The update focuses on better factual accuracy, stronger handling of dates, numbers, and sources, and introduces a new control that lets users adjust how deeply the AI reasons before responding.

The move comes as competition in the AI market intensifies, with rivals offering increasingly capable open-weight and lower-cost models. By bringing more powerful AI to free users, OpenAI is betting that wider access will strengthen ChatGPT's position as the world's most-used AI assistant.

Why It Matters

Advanced AI is no longer reserved for paying subscribers. Millions of users can now access smarter models and more capable reasoning, making high-quality AI assistance available for everyday work, learning, and creativity.

The Upside

Free users gain significantly more capable AI without subscription costs, while paid users benefit from improved accuracy and greater control over reasoning depth. This could accelerate AI adoption across students, professionals, and businesses.

The Downside

Even with stronger models, AI can still make mistakes or produce inaccurate information. Expanded access also increases infrastructure costs for OpenAI and raises expectations for reliability as millions more users rely on these systems daily.

Looking Ahead

The AI race is increasingly shifting from building the smartest models to making them available to everyone. OpenAI's latest rollout signals that premium-level AI capabilities are steadily becoming the new baseline rather than an exclusive feature.
