The specification change that matters is the context window moving from 32,000 tokens to 128,000 for smaller models and up to 256,000 for larger ones, because it changes which problems are solvable without infrastructure. A 32,000-token limit means retrieval, chunking and index management; at 128,000 many tasks fit whole and the workarounds become unnecessary. The deployment range runs from a browser with zero ongoing server cost through local runtimes to one-click hosted endpoints, and the strategically significant detail is interface compatibility — a local model speaking the same protocol as hosted APIs is substitutable without changing application code, which makes placement an operational choice rather than an architectural commitment. That is what makes open weights competitive: not being better, but making switching free.
