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.
