Compared to GPT-4, most of them are not super great, yeah. I've tested out most of the ones released for the last weeks and nothing have been getting the same quality of results, even the medium sized (30GB and up) models that require >24GB of VRAM to run GPU. I have yet to acquire hardware to run the absolute biggest of models, but I haven't seen any reports that they are much better either for general workloads.
