System design interview question
"Design an AI coding assistant that suggests code as a developer types in their editor. Suggestions must appear within a few hundred milliseconds or the developer has already typed past them, the model needs context from files it has not been given, and the code being edited is proprietary."
an extreme latency budget for an expensive model, plus context selection — deciding which fragments of a large codebase to include in a limited prompt. It differs from a chat assistant in that the user did not ask a question, the result must arrive before they type the next character, and most suggestions are discarded.
