OpenAI also released the weights for Whisper. Some model releases, like LLaMa from Meta, just contain the code for training and the data. You can train the weights yourself, but for LLaMa that takes multiple weeks on very expensive hardware.
(LLaMa also released the weights for researchers and they leaked online, but the weights are not open-source.)
When a company releases a model including the weights, you can download their pre-trained weights and run inference with them, without having to train by yourself.
