They have not improved in the one way that I use them today, which is coding. It is like talking to a halfwit, and I always end back up with codex.
Asking a direct question is not hostile. I'm glad to hear you've found a use for a smaller model that generates value. It gives me hope for the future, that said, I think we are still a long ways away from needing HPC in DC's.
Different people have different requirements. I use my local model for coding regularly. It doesn't help the conversation that things like quant, config, harness, and even prompting are equally as important to your outcomes as the choice of model.
