Q&A
READERS QUESTIONS OF THE WEEK
Why should a business use open-source AI instead of ChatGPT or Claude APIs?
Open-source models run on your own hardware or private cloud. You pay zero token markups to third parties, keep all customer data completely private, and cut monthly AI expenses by 60% to 80% on high-volume tasks.
Can these models run on a normal office computer?
Smaller models like Laya (300M) and quantized versions of Needle3 (14B) run easily on a modern laptop or a single desktop with a modest graphics card. Heavy models like Atria require dedicated cloud servers.
