In the LLM jargon from scratch means not fine tuning on top of an existing model that was trained by a big corp. Fine tuning the lies does not produce truth imo.

The books that worked for centuries, pubmed.gov articles, the "truth seeker people"s articles should be collected and the training should start on those. This is for health domain. Mike Adams is training one from scratch.

The truth is out there but needs some work to be found. It is not served freely to everyone.
