# Claude AI models now available for Lovable app features

> Lovable apps can now use Anthropic's Claude models (Fable 5.1, Opus 5.5, Opus 5, Sonnet 5, Haiku 4.5) for chatbots, document analysis, PDF field extraction, and structured output with no separate Anthropic account required. This expands developer options beyond OpenAI with access to Claude's capabilities.
