the ROI of parameter-efficient fine-tuning (PEFT
Read more ↗1. The first obvious ROI dimension to consider is direct cost savings gained from training and computing. With PEFT, you only fine-tune 1-5% of the parameters in a model. Unlike full fine-tuning, where the entire model is trained.…

Read more ↗1. The Big Idea Behind the Transformer Instead of reading a sentence word-by-word as in an RNN, the Transformer reads the whole sentence in parallel. This alone dramatically speeds up training. But then the natural question would be:…

Read more ↗1. LLMs Don’t Have Real Memory Only a Temporary “Work Scratchpad” LLMs do not store facts the way a human brain does. They have no memory database. They don't update their internal knowledge about a conversation. What they…

Read more ↗1. When You Have Limited Compute Resources This is the most common and most practical reason. Fine-tuning a model like Llama 70B or GPT-sized architectures is usually impossible for most developers or companies. You need: Multiple A100/H100 GPUs…
