  • Optional cloud access: Connect to services like OpenAI, Anthropic, Gemini and Groq when internet-based models are required
  • Custom assistants: Create tailored assistants for writing, coding, summarizing and more
  • OpenAI-compatible API: Includes a local API server at localhost:1337 for tools expecting the OpenAI format
