Если вы хотите быстро опробовать Gemini API, вы можете использовать команды curl для вызова методов REST API. В примерах этого руководства показаны вызовы каждого метода API.
Colab использует код Python для установки переменной среды и отображения изображения, но вам не нужен Colab для работы с REST API. У вас должна быть возможность запускать все примеры curl вне Colab без изменений, если у вас установлен API_KEY , как описано в следующем разделе.
Для каждой команды curl вы должны указать подходящее имя модели и ключ API.
Настройте свой ключ API
Чтобы использовать API Gemini, вам понадобится ключ API. Если у вас его еще нет, создайте ключ в Google AI Studio.
В Colab добавьте ключ к менеджеру секретов под знаком «🔑» на левой панели. Дайте ему имя GOOGLE_API_KEY . Затем вы можете добавить его как переменную среды для передачи ключа при вызове Curl.
В терминале вы можете просто запустить GOOGLE_API_KEY="Your API Key" .
import os
from google.colab import userdata
os.environ['GOOGLE_API_KEY'] = userdata.get('GOOGLE_API_KEY')
Gemini и API на основе Content
Только текстовый ввод
Используйте generateContent , чтобы сгенерировать ответ модели на входное сообщение. Если входные данные содержат только текст, используйте модель Gemini 1.5 или модель Gemini 1.0 Pro.

"text": "In the quaint town of Willow Creek, nestled amidst rolling hills and whispering willows, there lived an ordinary boy named Ethan. Ethan's life took an extraordinary turn the day he stumbled upon an enigmatic backpack hidden in the depths of his attic.\n\nCuriosity ignited within Ethan as he lifted the worn leather straps and unzipped its mysterious contents. Inside lay a shimmering array of vibrant objects and peculiar trinkets. There was a glowing orb that pulsated with an ethereal glow, a feather that seemed to have a life of its own, and a small, enigmatic key.\n\nAs Ethan explored each item, he realized they possessed astonishing abilities. The orb illuminated his path, casting a warm glow in the darkest of nights. The feather granted him the power of flight, allowing him to soar through the skies with newfound freedom. And the key opened a portal to a hidden world, a realm of endless wonder.\n\nArmed with his magical backpack, Ethan embarked on countless adventures. He flew over the towering mountains of Willow Creek, exploring their hidden secrets. He navigated the treacherous depths of the Enchanted Forest, where he encountered mythical creatures and ancient spirits. And he ventured into distant, unknown lands, uncovering lost civilizations and forgotten treasures.\n\nWith each adventure, Ethan's knowledge and abilities grew. He learned to harness the power of his backpack wisely, using its magic to help others and protect the world from evil forces. The backpack became an extension of himself, a symbol of hope and wonder in the face of adversity.\n\nAs the years went by, Ethan's reputation as the boy with the magic backpack spread far and wide. People from all walks of life came to him, seeking his guidance and protection. And Ethan never hesitated to lend a helping hand, using his extraordinary abilities to make the world a better place.\n\nIn the end, the magic backpack became more than just a collection of objects. It was a representation of Ethan's unwavering spirit, his boundless imagination, and his unwavering belief in the power of dreams. And as long as Ethan carried it with him, the magic of Willow Creek would live on, illuminating the darkest corners of the world with hope, wonder, and the limitless possibilities that resided within the heart of a child."

Ввод текста и изображений
Gemini предоставляет различные модели, поддерживающие мультимодальный ввод (модели Gemini 1.5), так что вы можете вводить как текст, так и изображения. Обязательно ознакомьтесь с требованиями к изображениям для подсказок .
Если ввод приглашения включает в себя как текст, так и изображения, используйте модель Gemini 1.5.
Следующие фрагменты помогут вам создать запрос и отправить его в REST API.

As her fingertips grazed the worn leather, a surge of warmth coursed through her body, and the backpack began to emit a soft, ethereal glow."
Конфигурация
Каждое приглашение, которое вы отправляете в модель, включает значения параметров, которые управляют тем, как модель генерирует ответ. Модель может генерировать разные результаты для разных значений параметров. Узнайте больше о параметрах модели .
Кроме того, вы можете использовать настройки безопасности, чтобы настроить вероятность получения ответов, которые могут считаться вредными. По умолчанию настройки безопасности блокируют контент со средней и/или высокой вероятностью небезопасного контента по всем параметрам. Узнайте больше о настройках безопасности .

"text": "Once upon a time, in a small town nestled at the foot of a majestic mountain range, lived a young girl named Lily. Lily was a bright and curious child who loved to explore the world around her. One day, while playing in the forest near her home, she stumbled upon a hidden cave. Intrigued, she stepped inside, and to her amazement, she discovered a dusty old backpack lying in a corner.\n\nCuriosity piqued, Lily reached out and picked up the backpack. As soon as her fingers brushed against the worn leather, she felt a strange tingling sensation coursing through her body. Suddenly, the backpack began to glow, emitting a soft, ethereal light that filled the cave.\n\nWith wide-eyed wonder, Lily opened the backpack to find it filled with an assortment of magical objects. There was a compass that always pointed to the nearest adventure, a magnifying glass that could reveal hidden secrets, a telescope that allowed her to see distant lands, and a book that contained the knowledge of the universe.\n\nOverjoyed with her discovery, Lily took the magic backpack home and began using its contents to explore the world in ways she had never imagined. She followed the compass to discover hidden treasures, used the magnifying glass to uncover the secrets of nature, gazed through the telescope to witness the wonders of the cosmos, and delved into the book to learn about the mysteries of the universe.\n\nAs Lily's adventures continued, she realized that the magic backpack was more than just a collection of enchanted items. It was a symbol of her own limitless potential and the power of her imagination. It taught her that with curiosity, courage, and a touch of magic, anything was possible.\n\nNews of Lily's magical backpack spread throughout the town, and soon, children from all around came to her, eager to learn about its wonders. Lily welcomed them with open arms, sharing her stories and inspiring them to embark on their own adventures.\n\nAnd so, the magic backpack became a beacon of hope and wonder, reminding everyone that the world is full of hidden treasures waiting to be discovered, if only one has the courage to step into the unknown."

Встраивание
Встраивание — это метод, используемый для представления информации в виде списка чисел с плавающей запятой в массиве. С помощью Gemini вы можете представлять текст (слова, предложения и блоки текста) в векторизованной форме, что упрощает сравнение и сопоставление вложений. Например, два текста, которые имеют схожую тему или настроение, должны иметь схожие вложения, которые можно идентифицировать с помощью методов математического сравнения, таких как косинусное сходство.
