open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
multimodal — A model that works with more than text — reading images, audio, or video, and sometimes generating them too.
fine-tuning — Taking a trained model and training it a bit more on your own examples so it gets better at one specific job.
