## AI overview

App.build adds support for running open-weight LLMs through Ollama, LMStudio, and OpenRouter to generate applications without depending on cloud APIs. The article discusses cost, rate-limit, privacy, and local-hardware considerations, including example inference speeds.

## Source excerpt

App.build now supports open weights LLMs via Ollama, LMStudio, and OpenRouter - enabling you to generate complete applications end-to-end without cloud API dependency or associated costs. Why Run App.build Locally? Zero API costs Cloud LLM APIs can become expensive fast during ex...
