I agree that 405B isn't practical for home users, but I disagree that it defeats the purpose of open source. If you're building a business on inference it can be valuable to run an open model on hardware that you control, without the need to worry that OpenAI or Anthropic or whoever will make drastic changes to the model performance or pricing. Also, it allows the possibility of fine-tuning the model to your requirements. Meta believes it's in their interest to promote these businesses. I'd think of the 405B model as the equivalent to a big rig tractor trailer. It's not for home use. But also check out the benchmark improvements for the 70B and 8B models.
