I think most of HN has only tried ChatGPT with GPT-3.5 in December 2022 when the OpenAI servers were getting hammered. That is why they're impressed by these slow and low quality local models and mistakenly think they're on par with OpenAI's offerings.
Honestly even reddit and teenagers on TikTok have a more accurate view on OpenAI vs. local LLMs than HN.
