The trick: Scope Swap
Free users got the unlimited model.
Paying users kept the one that is right more often.
free ChatGPT users now get unlimited text chats on GPT-5.6 Luna, the new Free and Go default, with factual errors 62% less common than GPT-5.5-Instant, per OpenAI's August 6 announcement, fully rolled out since the week of August 10.
Before you read on. Your call?
TRUE, BUT
62%
the giveaway is genuine and the word unlimited arrives pre-qualified. OpenAI's own sentence caps it: unlimited text chats come 'subject to abuse guardrails', which are not enumerated anywhere, and 'Limits will still apply for file uploads, images and other tools.' The 62% is a relative figure from OpenAI's internal testing, not an independent evaluation, with no published sample or task mix. And the tier split does the quiet work: Luna is the fast, cheap variant; the model OpenAI describes as more reliable with facts, GPT-5.6 Sol, is the one Plus and Pro subscribers pay for. Free users got more quantity. The accuracy upgrade is the product being sold.
