Introduction: Why LLM Performance Matters
Ever notice how your AI assistant starts snappy but then… starts dragging or slowing down?
It’s not just you. That slowdown is baked into how large language models (LLMs) work. Most of them generate text one token at a time using something called autoregressive decoding. And here’s the catch – the longer the response gets, the more work the model has to do at every step. So the lag adds up.
