From GPT‑4 to Claude, these models have become the backbone of many developer‑centric tools—code completion, documentation generation, automated testing, and even full‑stack scaffolding. Yet, the dominant deployment paradigm remains cloud‑centric: developers send prompts to remote APIs, await a response, and then act on the output. ...
