----------
Every time an LLM generates text, it has to make a decision - which token comes next? The strategy it uses to make that decision directly affects output quality, speed, and cost. Greedy decoding and beam search are two of the most fundamental decoding strategies in modern LLM systems, and this is a question asked consistently in AI Engineer and GenAI interviews at FAANG, MNCs, and top AI startups in 2026.
We cover what greedy decoding is and why it always picks the most probable next token, how beam search improves output quality by keeping top-k sequences at every step and selecting the best at the end, a visual walkthrough of how both strategies navigate token probability trees differently, and a direct side-by-side comparison across memory, output quality, compute cost, and best use cases. A practical interview tip is included covering exactly when to recommend each strategy based on latency and quality requirements.
If you are preparing for AI Engineer, ML Engineer, or GenAI roles in 2026 - or building production LLM inference pipelines where decoding strategy directly impacts performance - this lecture gives you the depth to answer confidently.
