Like &amp;quot;these are the techniques that work best for lightweight models&amp;quot; but not necessarily assuming those as a general rule of thumb for &amp;quot;heavyweight models.&amp;quot;&lt;p&gt;Even something like the discussion of synthetic data on model collapse is a good example of where there might be a very significant difference in the effect on model quality for a cheaper and less sophisticated model generating synthetic data to feed back into itself and a much more complex and sophisticated model. Maybe the lesson is actually &amp;quot;recursive training on synthetic data leads to model collapse &lt;i&gt;in lightweight and medium weight models&lt;/i&gt;.&amp;quot;&lt;p&gt;So while the writeup is a great one on fine tuning 7B models with LoRA, I would be curious just what % of the recommendations hold true in replication for even just a 65B model.</text><parent_chain></parent_chain></comment><story><title>Practical Tips for Finetuning LLMs Using LoRA (Low-Rank Adaptation)</title><url>https://magazine.sebastianraschka.com/p/practical-tips-for-finetuning-llms</url></story>

Especially since you can host many LoRA adapters at once for a fraction of the cost of hosting an entire model by sharing the base between the adapters. I built a little tool to make LoRA fine-tuning easier. The adapters export to Huggingface.
