Claim: LLMs let teams skip months of data collection by prompting or synthetic generation, but production needs benchmarks and cost controls. Example: YouTube experiments classify “is this video part of a series” using only titles, 10 examples in the prompt, a smaller 8B model in batch, and hits about 0.88 accuracy on a golden benchmark. Pipeline choices include synthetic data augmentation for rare cases and swapping LLM embeddings into cheaper downstream models to cut inference cost.
