🧬📏💪🏻[Genstruct 7B](https://huggingface.co/NousResearch/Genstruct-7B) is an instruction-generation model, designed to create valid instructions given a raw text corpus. This enables the creation of new, partially synthetic instruction finetuning datasets from any raw-text corpus. You can build with this endpoint using🧬📏💪🏻[Genstruct 7B](https://huggingface.co/NousResearch/Genstruct-7B) available here : [NousResearch/Genstruct-7B](https://huggingface.co/NousResearch/Genstruct-7B).

examplecofee = """A cortado is a Spanish beverage consisting of espresso mixed with a roughly equal amount of warm milk to reduce the acidity,[1][2] although the exact ratios have considerable regional variation.[3] The milk in a cortado is steamed, but not frothy and "texturized" as in many Italian coffee drinks.[4] The cortado is commonly served all over Spain.[5] The word cortado is the past participle of the Spanish verb cortar (to cut), in the sense of "dilute", and can refer variously to either coffee or espresso drinks throughout Spanish and Portuguese speaking countries."""
