Replit Launches Free Mode with GPT-5.6 Luna for Software Creation

Replit has launched Free Mode, powered by GPT-5.6 Luna, enabling users to turn their ideas into working software without worrying about token costs. This new feature is set to democratize software creation, making it accessible to a broader audience.

Impact on Developers

Developers who previously subscribed to a GLM Coding Plan are now limited to the OpenAI Chat Completions-compatible protocol. Despite this, Replit's new offering provides a cost-effective alternative for those looking to build software.

Pricing and Availability

On the API, the price remains unchanged from GLM-5.2: $1.40 per million input tokens and $4.40 per million output tokens. Cached input costs $0.26 per million tokens, while Replit currently lists cached-input storage as free for a limited time.

Benefits of GPT-5.6 Luna

Replit claims that GPT-5.6 Luna offers substantially stronger coding and long-horizon agent performance, making it a powerful tool for developers.

• Stronger coding capabilities: GPT-5.6 Luna provides enhanced coding performance.
• Long-horizon agent performance: The model is designed to handle complex tasks over extended periods.
• Cost-effective alternative: Replit's new offering is more affordable compared to other options.
