#  Introduction   Thanks especially to contemporary large language models, natural language processing (NLP) is a fundamental pillar of modern AI and software systems. You'll find NLP techniques and technologies powering everything from search engines and chatbots to automated customer support routing and entity extraction pipelines. When it comes to production-grade NLP in Python, spaCy is the undisputed industry standard. spaCy is designed specifically for production use, offering industrial-strength speed, pre-trained statistical and transformer models, and an intuitive API. Unfortunately, many developers treat spaCy as a simple black box monolith. They load a model, run it on text, and accept the default processing speeds and extraction limits. When scaling from a local prototype to processing millions of documents, these default configurations can become computational bottlenecks, leading to latency, bloated memory footprints, and missed domain-specific entities.…
