Your model repeats phrases and gets stuck in loops on long generations. How do you fix degeneration?
Neural text degeneration is a known failure of likelihood-maximizing decoding, not a broken model. The fixes are specific decode-time knobs. Here is which lever to reach for and what each one costs.
Updated Sep 2026 · Grounded in real GenAI, LLM, and AI/ML engineering interview loops and written to a senior-engineer editorial bar.
Neural text degeneration is a known failure of likelihood-maximizing decoding, not a broken model. The fixes are specific decode-time knobs. Here is which lever to reach for and what each one costs.
Lead with where the obvious approach breaks, because that is the judgment they are screening for — most candidates jump straight to the happy path and lose the room.
Then walk the failure back through the pipeline in order, naming the one metric the customer's exec sponsor actually cares about before you propose the fix.
