In our previous chapters, we laid the groundwork for using LangExtract by setting up your environment and understanding how to define extraction tasks using schemas. Now, it&rsquo;s time to get to the heart of the matter: the LangExtract API itself.</p> <p>This chapter will guide you through the core functions that empower you to perform structured information extraction. We&rsquo;ll focus primarily on the star of the show: the <code>langextract.extract()</code> function. You&rsquo;ll learn how to use its various parameters to precisely control your extraction tasks, from specifying your input text to selecting the underlying Large Language Model (LLM) and fine-tuning performance.</p>
