From Cloud APIs to Running Fine-Tuned AI Models on Your Own Hardware

What if I tell you, that $500 monthly API bill is optional. So is the “We need a GPU server to run this model”. The engineers who know about quantisation and LoRA are quietly running the same models at a tenth of the cost, on hardware they already own. The ones who don’t are signing cloud invoices. I was in the second group until recently and now am documenting my learnings and findings. Learn these two things and your relationship with AI infrastructure changes permanently. Your costs drop. Your latency drops.
