This is the honest, numbers-first breakdown of running large language models locally versus in the cloud in 2026 — including the costs that hide in the corners.

Local models were slow, clumsy, and a fraction as capable as the frontier systems you could reach through an API. If you wanted quality, you paid per token and moved on with your life. That equation has quietly inverted for a large and growing set of use cases, and the reason is not a single breakthrough but the accumulation of many. Open-weight models in the 7-billion to 70-billion parameter range now handle the bulk of everyday tasks — summarization, classification, extraction, retrieval-augmented generation, routi...
