Frequently asked questions

Quick answers.

What is a multimodal language model?

A multimodal language model extends a language model to handle more than text, such as images, audio and video, so one system can read, see, listen and respond. Some can also generate images or speech.

How is it different from a vision language model?

A VLM handles images (and sometimes video) plus text. Multimodal is the broader term and also covers audio and speech. Every VLM is multimodal, but not every multimodal model is only a VLM.

What does omni or any-to-any mean?

It describes models that accept several input types and can produce several output types, for example listening to speech and answering in speech, from one model.

Are multimodal models more error-prone?

They can misread small visual details, mishear audio or invent content. Verify important results and test on your own data.

How do I choose between an API and an open model?

APIs are quick to start and managed for you. Open models give more control over data and cost but you host and tune them. Evaluate on your own tasks.
