Replit said GPT-5.6 Luna now powers Free Mode, letting millions of users build apps, agents and other software without paid usage.
Recent OpenAI price cuts and GPT-5.6 Luna’s improved price-performance removed a key cost barrier that had limited wider rollout of software creation tools.
Free Mode gives users fast answers, suggestions, feedback and analysis inside the same project environment, helping them plan and refine ideas before moving into Build Mode.
When tasks need deeper reasoning, Replit can route them to GPT-5.6 Sol and then return users to Luna-powered Free Mode while preserving project context.
Replit and OpenAI framed the launch as a step toward expanding software creation beyond specialists, with Replit saying the addressable builder base could grow 100x.
