ChatGPT opens latest AI model access to free users

OpenAI is set to democratize access to its cutting-edge artificial intelligence by making its latest model available to free users. The company announced that a lightweight version of its GPT-5.6 model, named 'Luna,' will be accessible to all users, removing previous limitations that required paid subscriptions for advanced AI capabilities.

Luna is described as the fastest and most cost-effective among the components of GPT-5.6. It will serve as the default model for both free and low-cost 'Go' subscription tiers. While OpenAI has not provided an exact date, they indicated that free users could expect access as early as next week, allowing for unlimited text-based conversations.

We will make the lightweight model 'Luna' of GPT-5.6 available to users without limits.

However, certain functionalities, such as file uploads and image generation, will continue to have usage limits, even for users accessing the Luna model. OpenAI stated that the primary goal behind this initiative is to provide a more advanced AI experience to a wider audience. "Through updates, more people will be able to continue asking questions, developing ideas, and getting help when they need it," the company said.

Despite OpenAI's stated intentions, industry observers suggest that the move might also be a strategic response to increasing competition. The performance of low-cost Chinese AI models has been steadily improving, potentially pressuring OpenAI to engage in more aggressive price competition to maintain its market share.
