Build AI Apps Instantly with Replit AI Integrations

Traditionally, building AI apps required complex initial setup steps such as creating developer accounts, obtaining API keys, and reviewing documentation. However, with Replit AI Integrations, developers can now build AI apps instantly within the Replit environment without any of this hassle.

Users can start development simply by requesting the desired functionality from Replit Agent, without needing to create separate accounts or manage API keys. Replit automatically handles credential provisioning, model connection, and billing integration in the background.

The major available models are as follows:

• GPT: Text and image models
• Gemini: Multimodal (text, image, audio/video) models
• Claude: Text and reasoning models
• OpenRouter-based models: Over 300 models including Llama, Grok, Mistral, and more

Replit Agent automatically selects the optimal model depending on the task. It uses GPT for general text and image tasks, Gemini for multimodal inputs like audio or video, and OpenRouter models when special-purpose or open-weight models are needed.

All usage and costs can be transparently checked on the Replit dashboard, and pricing follows a structure based on public API rates.
