Introduction
OpenAI, a global leader in artificial intelligence research and development, announced on Thursday that its advanced language model, GPT-5.6 Luna, will soon become the default and primary model for users of the popular ChatGPT app across its free tiers. Most importantly, these users will gain access to unlimited text-based chats for the first time, effectively eliminating one of the longest-standing and most frustrating technical friction points for the platform’s broad non-paying audience. These major updates arrive at a critical time as the company strives to maintain its technological dominance and attract millions of new users worldwide to compete with new market players.

What is actually changing on the digital platform?
The prominent tech company, which reports that ChatGPT now reaches more than 1 billion active weekly users globally, explained that it will roll out the new Luna model as the free default choice for everyone during the course of this week. This will be accompanied by unlimited text chat capabilities, as well as the launch of an innovative new thinking button rolling out to all platforms during the week of August 10 to enhance analytical capacity. The Luna model is the smallest, fastest, and most efficient language model in the broader GPT-5.6 family launched to the public on July 9. According to OpenAI’s ongoing internal evaluations, responses containing at least one factual and informational error were significantly less common by a comfortable 62 percent using the advanced Luna model compared to GPT-5.5 Instant, the older model it now replaces as the free default choice. Notably, this unlimited access applies exclusively to written text chats, while strict limitations remain in place for large file uploads, complex image processing, interactive voice features, and high-quality photo generation due to server constraints. The company emphasizes that this free offering remains subject to strict guardrails to prevent potential misuse by bad actors or bots.
Model features for subscribers and paid tier professionals
For professional users and subscribers to premium paid tiers like Plus and Pro, OpenAI is rolling out an updated and fully optimized version of the GPT-5.6 Sol model, carefully tuned for continuous daily chats and office tasks. The company stated in its official announcement that this professional edition delivers more focused, direct answers, intelligently adapts its level of detail to match the user’s question, avoids unnecessary formatting, and provides factual corrections when simply agreeing with the user is unhelpful or misleading. Internal company data indicates that factual errors are 68 percent less common with the updated Sol model compared to the older GPT-5.5 Instant. Paid users also gain an exclusive thinking slider tool that allows them to adjust the depth of logical reasoning and analysis applied by the model for complex queries.
The heated competitive landscape and rapid price cuts
This strategic move comes amid fierce pressure from Chinese open-weight AI models, which are among the cheapest in the industry and have shaken up markets, forcing Western labs to justify their high pricing, as noted by Axios in a recent report. In a swift reaction to this competitive threat, OpenAI slashed API developer pricing for the Luna model by 80 percent on July 30, just three weeks after its official launch—a pace much faster than typical market price cuts, reflecting the company’s drive for dominance.
Excessive safety concerns, mental health, and guardrails
Meanwhile, CNET highlighted potential psychological and social risks resulting from unlimited access for emotionally vulnerable users, pointing to ongoing lawsuits in U.S. courts alleging that excessive engagement with chatbots has worsened mental health issues among young people. In response, OpenAI management reassured the public that it has implemented strong guardrails and security algorithms to prevent smart models from engaging in romantic roleplay, age-restricted challenges, or serving as a substitute for real-world human relationships—particularly for users under 18.
