1+ mon, 1+ week ago   (1231+ words) How modern RAG pipelines work, what they look like in production, and how they've evolved beyond the naive "embed, search, stuff" pattern. Retrieval Augmented Generation (RAG) is a pattern for giving a language model access to information it wasn't trained…...

1+ mon, 1+ week ago   (849+ words) When the original prompt-engineering playbook was written, the state of the art was GPT-3.5, and you could roughly double a model's math accuracy by appending Let's think step by step to your prompt. That trick worked because the base model…...
