"The model is open source." Half the time, it is not. Open weights and open source are not the same thing, and mixing them up is how mistakes get made. - Open weights means you can download the parameters. That is the whole definition. It says nothing about what you may do with them. - Open source properly means the license meets the Open Source Definition: free use, modification, redistribution, no field-of-use discrimination. - Many "open" models fail that test via user thresholds or use restrictions. They are open weights with strings attached. - Procurement angle: answer "is this open source?" with the license name and a link, not "well, the weights are downloadable." Stop shopping by label, start shopping by license text. And PrivateLLM deploy sets up the licensed model on your own AWS for $50 plus usage.
