// cómo funciona

Cómo funciona

  1. Install the runtime

    One binary or app gets you a working local model setup.

  2. Download a model

    Pick a size that fits your RAM/VRAM; smaller models run on laptops.

  3. Chat or integrate

    Use the built-in UI, or point OpenAI-compatible clients at it.

  4. Go private

    Airplane mode works — your prompts never leave the device.
