In a certain sense, all open models skimp on fine-tuning. Since ChatGPT gets user feedback, OpenAI theoretically sits on a growing pile of data that can be used for continuous fine-tuning and alignment. For local models, you'd have to look for new checkpoints every few months or track good and bad responses and do your own alignment.
