# OpenAI expands GPT-5.6 Luna access to free users with unlimited text chats

> OpenAI is making its GPT-5.6 Luna model the default for free ChatGPT users and, more strikingly, giving them unlimited text conversations. The move is possible because of cost, not charity: OpenAI cut the model's price by roughly 80 percent in July, to around 20 cents per million input tokens, cheap enough that near-frontier chat can be handed to everyone without metering each message. There are upgrades for paying users too. A new Think button lets Pro subscribers dial up reasoning for harder questions, while a companion model, GPT-5.6 Sol, is tuned for factual accuracy and adds a slider to trade speed against depth of reasoning. The pattern is the same across the industry: capability that was premium a year ago is quickly becoming the baseline. Unlimited free access is a competitive weapon as much as a feature, aimed squarely at rivals courting the same casual users. It also keeps ratcheting up expectations, because once unlimited high-quality chat is free, the pressure shifts to whatever comes next, and to how these tools get paid for at scale.
