Prefill vs. decode intuition LLM inference has two distinct phases. Prefill builds understanding from the prompt. Decode generates one token at a time. The first phase is about comprehension. The second is about execution. Engineering follows the same pattern. Spend more time understanding the problem than implementing the solution. A faster decode rarely compensates for a poor prefill. Good systems optimize both. #ai #llm #inference #systems #devthoughts
