On August 18, 2026, Replit introduced Free Mode, an Agent mode powered by OpenAI's GPT-5.6 Luna in which everyday tasks did not use credits. Replit announced it in Replit Introduces Free Mode to Expand What is Possible with AI, together with the renaming of Economy Mode to Power Mode and a redesigned interface.

What Replit announced

• Free Mode: an Agent mode powered by OpenAI's GPT-5.6 Luna, in which everyday tasks did not use credits.
• Claim for Core subscribers: Replit said Core subscribers could create 30X more than before with Free Mode, plus up to 30 hours of chat per month, for $20 per month.
• Usage limits: Core and Pro users could use Free Mode until they reached usage limits that reset every 5 hours, or keep building in Power or Max Mode. Pro users got higher limits.
• Power Mode and Max Mode: Power Mode, formerly Economy Mode, used cost-optimized models and delivered the same or better performance than Economy Mode for the same cost. Max Mode used higher-performance models for complex work.

What it means for people building with AI

Everyday agent tasks in Free Mode did not use credits, up to usage limits that reset every 5 hours, so a flat subscription covered more of the routine work. Heavier work could continue in Power or Max Mode, and Replit Agent might suggest switching for more complex or high-value tasks.

Redesigned interface

Replit also launched a redesigned interface that moved between quick chat, tasks and complex builds and carried context across projects.
