Replit expands access to software creation with GPT-5.6 Luna
As models become more capable, their economics are changing just as quickly. Better price performance makes advanced intelligence practical across more products, more workflows, and more moments. For software creation, that shift is narrowing the distance between having an idea and building something that works.
Replit(opens in a new window) and OpenAI have long shared a goal: making software creation accessible to anyone with an idea, regardless of technical background. Replit was an early user of GPT‑3, building with OpenAI models as natural-language software development began to take shape. Now, GPT‑5.6 Luna is powering Replit Free Mode, showing how the price performance of the GPT‑5.6 series and recent OpenAI price cuts can translate into broader access at scale.
“For the first time, you'll get access to an amazing experience where you can build applications, build agents, build all sorts of software in Free Mode. And that's powered by GPT-5.6 Luna.”
—Amjad Masad, Co-Founder and CEO, Replit
Making capable models available at scale
For Replit, model cost was one of the final barriers to making software creation widely accessible. GPT‑5.6 Luna combines the capability, price performance, and reliable inference at scale needed to make Free Mode available to millions of users.
“Thanks to OpenAI and the price cuts that you made recently, you made it possible for us to offer it to millions of users in Free Mode.”
—Amjad Masad, Co-Founder and CEO, Replit
Helping anyone shape an idea before they build
With Replit Free Mode, users can get fast, accurate answers, suggestions, feedback, and analysis in seconds without consuming usage. Because Agent understands the full context of a user's projects, it can help them plan, ideate, shape, optimize, and explore ideas before they move into Build Mode.
That continuity matters. Instead of treating exploration as separate from creation, Replit lets anyone develop an idea in the same environment where it can become working software. When a task requires more advanced reasoning, Replit can route it to GPT‑5.6 Sol, then return to Free Mode powered by GPT‑5.6 Luna while preserving project context.
For OpenAI and Replit, Free Mode is an example of what better model economics can unlock. As intelligence becomes more capable and affordable, software creation can extend beyond a small group of specialists to anyone with an idea and an internet connection.
“If we can get to a world where anyone with access to the internet can build a product, build a startup, and just kind of get started and get going, I think we're going to see another renaissance-level entrepreneurial boom like we've never seen before.”
—Sam Altman, CEO, OpenAI
That opportunity expands who can use software to solve a problem, improve a community, or make an idea real. Masad calls software "such an empowering tool" and says that increasing the number of people able to build by 100x would open that opportunity far more widely.
By pairing GPT‑5.6 Luna with an experience built around project context, Replit is turning improved model price performance into wider access. It is a step toward the shared vision behind the partnership: anyone with an idea should be able to build.
