Which AI model is right for your task?

Claude, Gemini, GPT, Grok, it’s a lot to navigate, especially as each model comes with its own quirks and limitations. You shouldn’t have to become an AI expert just to get things done!

Meet “Auto”

At Invent, we believe the smartest AI is invisible. That’s why we created Auto, an assistant that auto-selects the best AI model for your input, whether you’re working with documents, images, videos, or audio.

  • No guessing
  • No technical headaches
  • Just results

Each model has its logo and name in a rounded white button. The background is light with a soft blue gradient in the corner, suggesting automated or dynamic AI model selection.

How does Auto decide?

By default, it uses GPT-4.1, but if you upload a file that’s not supported (like certain documents, audio, or video), it automatically switches to a broader model with more file support, such as Gemini Flash 2.

Is Auto perfect? Not yet! But it’s always working hard behind the scenes to choose the smartest tool for the job and give you the best possible response.


Not all models are created equal

Here’s the truth:
Most models cover text and images. But support for documents, audio, and video? It drops off quickly.

  • Claude and ChatGPT can process some documents, but support is patchy and limited to certain file types.
  • Grok does text and images, and that’s about it.
  • Gemini is the only true “beast” that natively supports documents, audio, and video, in addition to text and images.

Why “Auto” changes the game for UX

  • Zero Guesswork: You never have to wonder, “Is this the right model for my file?”
  • Universal Coverage: Text? Images? PDF? Podcast? YouTube video? Just upload and done!
  • Always Optimized: Auto intelligently chooses the best model for your specific file, maximizing quality and accuracy.


Real-world examples that show the Magic

  1. Upload a PDF or Word file: Auto knows which model reads it best and extracts the information you need.
  2. Submit an audio recording or video: Auto routes it to the right AI, providing the most accurate transcript or summary.
  3. Want to analyze an image, then ask questions about its content? Auto automatically combines model strengths for perfect results.

With Invent’s Auto, you get the power of the latest AI, across every format without ever having to think about model details or format restrictions.
