Создано с помощью Nano Banana 2 Запрос: "Фотография обложки глянцевого журнала. На минималистичной синей обложке крупными жирными буквами написано Nano Banana. Текст набран шрифтом с засечками и занимает весь экран. Никакого другого текста быть не должно. Перед текстом – портрет человека в элегантном минималистичном платье. Она держит цифру 2, которая находится в фокусе.
В углу укажите номер выпуска и дату "Февраль 2026 г.", а также добавьте штрихкод. Журнал лежит на полке у оранжевой оштукатуренной стены в дизайнерском магазине". -
Создано с помощью Nano Banana Pro Запрос. Создай понятное изометрическое 3D-изображение в виде миниатюрной мультяшной сцены, показывающей Лондон с его самыми известными достопримечательностями и архитектурными элементами: Используй мягкие, утонченные текстуры с реалистичными материалами PBR и мягким, реалистичным освещением и тенями. Интегрируйте текущие погодные условия непосредственно в городскую среду, чтобы создать захватывающее атмосферное настроение. Используй чистую минималистичную композицию с мягким однотонным фоном. Вверху по центру размести заголовок "Лондон" крупным полужирным шрифтом, под ним – заметный значок погоды, а затем дату (мелким шрифтом) и температуру (средним шрифтом). Текст должен быть выровнен по центру с одинаковыми интервалами и может слегка перекрывать верхние части зданий". -
Создано с помощью Nano Banana 2 Запрос. "Найди в Google Картинках изображения птицы квезаль. Создай красивые обои с этой птицей в формате 3:2, с естественным градиентом сверху вниз и минималистичной композицией". -
Создано с помощью Nano Banana Pro Запрос: "Помести этот логотип на рекламу духов с ароматом банана. Логотип идеально вписан в бутылку". -
Создано с помощью Nano Banana Pro Запрос: "Фотография повседневной сцены в оживленном кафе, где подают завтрак. На переднем плане – аниме-персонаж с синими волосами, один из людей нарисован карандашом, а другой – из пластилина". -
Создано с помощью Nano Banana Pro Запрос: "Найди в интернете информацию о том, как был воспринят запуск Gemini 3 Flash. Напиши на основе этой информации короткую статью с заголовками. Верни фото статьи, как если бы она была опубликована в глянцевом журнале о дизайне. Это фотография одной сложенной страницы со статьей о Gemini 3 Flash. Одно главное фото. Заголовок с засечками". -
Создано с помощью Nano Banana Pro Запрос: "Значок с изображением милой собаки. Фон белый. Сделай значки в ярком и тактильном 3D-стиле. Текста нет". -
Создано с помощью Nano Banana 2 Запрос: "Сделай фото с идеальной изометрией. Это не миниатюра, а фотография, которая случайно оказалась идеально изометрической. Это фотография красивого современного сада. На изображении показан большой бассейн в форме цифры 2 и надпись "Nano Banana 2".
Nano Banana – это название встроенных возможностей Gemini по созданию изображений. Gemini может генерировать и обрабатывать изображения в диалоговом режиме с использованием текста, изображений, видео или их комбинации. Это позволяет создавать, редактировать и повторять визуальные эффекты с беспрецедентным контролем.
Выбор модели
Nano Banana – это следующие модели, доступные в Gemini API:
- Nano Banana 2.1 (Gemini Nano Banana 2.1)
(
gemini-nano-banana-2.1). Обновленная версия Nano Banana 2, которая служит основной высокоэффективной рабочей моделью для генерации изображений и редактирования в чате. Она работает так же быстро и эффективно, как Flash, но при этом обеспечивает более высокое качество изображений, отрисовку текста, согласованность в многоэтапных диалогах и обоснование в Google Поиске в разрешениях 1K, 2K и 4K. - Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image)
(
gemini-3.1-flash-lite-image). Самая быстрая и дешевая модель Gemini для создания изображений. Она разработана для ситуаций, когда скорость и стоимость являются основными операционными ограничениями. Не оптимизирована для работы с несколькими референсными изображениями или для пошагового редактирования. - Nano Banana 2 (Gemini 3.1 Flash Image)
(
gemini-3.1-flash-image). Высокоэффективная модель предыдущего поколения, которая сочетает в себе высокую скорость работы, возможность генерировать изображения в разрешении 4K, обширные знания о мире и способность создавать изображения на основе нескольких референсов. Для всех новых проектов рекомендуется использовать Nano Banana 2.1. - Nano Banana Pro (Gemini 3 Pro Image)
(
gemini-3-pro-image). Премиум-модель для самых сложных визуальных задач. Она обладает обширными знаниями о мире, поддерживает расширенную локализацию, точно передает фирменный стиль и позволяет детально настраивать творческий процесс. - Nano Banana (Gemini 2.5 Flash Image) (
gemini-2.5-flash-image). Первая модель в серии Nano Banana. Хотя это надежная рабочая лошадка, рекомендуемый путь миграции – перейти на Nano Banana 2 Lite, чтобы оценить улучшенное качество, более высокую скорость генерации и более низкие цены на API.
Все сгенерированные изображения содержат водяной знак SynthID.

- Gemini 3.1 Flash Lite Image поддерживает только разрешение 1K.
- Улучшенная отрисовка текста. Модель способна генерировать разборчивый стилизованный текст для инфографики, меню, диаграмм и маркетинговых объектов.
- Обоснование с Google Поиском. Модель может использовать Google Поиск как инструмент для проверки фактов и генерировать изображения на основе данных в реальном времени, например текущих карт погоды, биржевых графиков и недавних событий.
- Не поддерживается моделью Gemini 3.1 Flash Lite Image.
- Gemini Nano Banana 2.1 и Gemini 3.1 Flash Image интегрированы с Google Картинками и веб-поиском.
- Режим мышления. Модель использует процесс "мышления" для обработки сложных запросов. Она генерирует промежуточные изображения (они видны в серверной части, но за них не взимается плата), чтобы улучшить композицию перед созданием окончательного высококачественного результата.
- До 14 референсных изображений. Вы можете использовать до 14 референсных изображений, чтобы создать итоговое.
- Новые соотношения сторон. Gemini 3.1 Flash Lite Image поддерживает соотношения сторон
1:1,3:2,2:3,3:4,4:3,4:5,5:4,9:16,16:9и21:9.
Используйте до 14 референсных изображений
Модели Nano Banana позволяют смешивать до 14 референсных изображений. Эти 14 изображений могут включать:
| Изображение Gemini 3.1 Flash Lite | Gemini Nano Banana 2.1 и Gemini 3.1 Flash Image | Изображение Gemini 3 Pro |
|---|---|---|
| До 14 изображений объектов с высокой точностью, которые будут включены в итоговое изображение. | До 10 изображений объектов с высокой точностью, которые будут включены в итоговое изображение. | До 6 изображений объектов с высокой точностью, которые будут включены в итоговое изображение. |
| Н/Д | До четырех изображений персонажей, чтобы сохранить их постоянство. | До пяти изображений персонажей, чтобы сохранить их внешний вид. |
| Н/Д | Н/Д | До трех изображений, которые будут использоваться в качестве референсов по стилю. |

Обоснование с Google Поиском для изображений (Nano Banana 2.1 и 3.1 Flash)
Обоснование с помощью Google Картинки позволяет моделям использовать изображения из интернета, полученные через Google Картинки, в качестве визуального контекста для генерации изображений. Поиск изображений – это новый тип поиска в существующем инструменте "Обоснование с Google Поиском", который работает наряду со стандартным веб-поиском.
Чтобы включить поиск изображений, настройте инструмент google_search в запросе к API и укажите image_search в массиве search_types. Поиск картинок можно использовать отдельно или вместе с веб-поиском.

Требования к показу
Если вы используете Поиск по картинкам в рамках обоснования с Google Поиском, вы должны показывать search_suggestions, полученный на шаге google_search_result. Полные требования к использованию приведены в Условиях использования.
Ответ
Для обоснованных ответов, полученных с помощью поиска по картинкам, API возвращает встроенные цитаты и метаданные атрибуции в рамках шагов ответа:
url_citationannotations – встроенные цитаты в блоке текстового контента вmodel_output, связывающие сгенерированный контент с его источником.google_search_result– содержитsearch_suggestions, фрагмент HTML-кода для показа подсказок при поиске в интерфейсе.
Генерация изображений на основе видео (Nano Banana 2.1, 3.1 Flash и 3.1 Flash Lite)
Генерация изображений на основе видео позволяет создавать новые изображения, используя контекст видео в качестве мультимодального референса. Это полезно для создания высококачественных значков видео, кинематографических постеров, сводной инфографики или новых иллюстраций, вдохновленных сценой из видео.
При генерации модель анализирует кадры видео в контексте, чтобы извлечь визуальные темы и ключевые события, а затем использует их вместе с вашим текстовым запросом для синтеза выходного изображения.
Вы можете передавать общедоступные URL YouTube напрямую в запросе к API или загружать локальные видеофайлы с помощью Files API.

Генерируйте изображения с разрешением до 4K.
По умолчанию модели Gemini 3 генерируют изображения с разрешением 1K, но также могут создавать изображения с разрешением 2K, 4K и 512 пикселей (0,5K) (только Gemini 3.1 Flash Image). Чтобы создать объекты с более высоким разрешением, укажите image_size в response_format.
Буква "K" должна быть заглавной, например 512px (05.K), 1K, 2K, 4K. Параметры, написанные строчными буквами (например, 1k), будут отклонены.

Процесс рассуждения
Модели изображений Gemini 3 – это думающие модели, которые используют процесс рассуждения ("Думающая") для сложных запросов. Эта функция включена по умолчанию, и ее нельзя отключить в API. Подробнее о том, как работает Gemini Thinking, рассказывается в руководстве.
Модель генерирует до двух промежуточных изображений, чтобы проверить композицию и логику. Последнее изображение в разделе "Размышления" – это итоговое сгенерированное изображение.
Вы можете посмотреть, как Gemini рассуждал, чтобы создать итоговое изображение.

Текст с изображениями
Стандартные модели генерации изображений создают только изображения, но некоторые продвинутые модели Gemini 3 (например, gemini-3-pro-image) могут генерировать чередующийся контент, например истории или инструкции, содержащие как текстовые блоки, так и иллюстрации в одном ответе.
Поскольку выходные данные являются сложными и чередующимися, удобные свойства, такие как .output_image или .output_text, не будут захватывать всю последовательность. Чтобы получить доступ к чередующемуся контенту и сохранить его, необходимо вручную выполнить итерацию по steps:
Python
interaction = client.interactions.create(
model="gemini-3-pro-image",
input="Write the story of the lifecycle of a monarch butterfly, interleave illustrations",
)
image_counter = 1
for step in interaction.steps:
if step.type == "model_output":
for content_block in step.content:
if content_block.type == "text":
print(content_block.text)
elif content_block.type == "image":
filename = f"butterfly_lifecycle_{image_counter}.png"
with open(filename, "wb") as f:
f.write(base64.b64decode(content_block.data))
print(f"\n[Saved illustration: {filename}]\n")
image_counter += 1

Другие режимы генерации изображений
Хотя для большинства случаев рекомендуется использовать модели Nano Banana, вы также можете попробовать специализированные модели для создания изображений:
- Imagen: Устаревшие модели Google для создания изображений по описанию (отключены).
- Veo – модель генерации видео от Google.
Генерировать изображения в пакетном режиме
Все возможности генерации изображений, описанные на этой странице, также можно использовать в пакетных заданиях с помощью Batch API. Это идеальный вариант, если вам нужно сгенерировать много изображений. Вы получите более высокие лимиты на количество запросов, но время обработки может составить до 24 часов.
Руководство по запросам и стратегии
В этом разделе приведены примеры запросов и шаблоны для распространенных рабочих процессов генерации и редактирования изображений. Каждый пример включает шаблон, который можно использовать повторно, и пример запроса для Interactions API.
Запросы для генерации изображений
Ниже приведены примеры того, как использовать текстовые запросы для создания изображений разных типов.
1. Фотореалистичные сцены
Подробно опишите сцену. Чем точнее вы будете, тем больше у вас будет контроля над результатами.

7. Постоянство персонажа: панорамный вид
Вы можете сгенерировать панорамные изображения персонажа, поочередно запрашивая разные ракурсы. Чтобы получить наилучшие результаты, включайте ранее сгенерированные изображения в последующие запросы. Это поможет сохранить единообразие. Для сложных поз добавьте референсное изображение.

Рекомендации
Чтобы улучшить результаты, используйте в работе эти профессиональные стратегии.
- Будьте максимально конкретны. Чем больше деталей вы предоставите, тем больше у вас будет контроля. Вместо "фэнтезийная броня" опишите ее: "богато украшенная эльфийская броня с узорами из серебряных листьев, высоким воротником и наплечниками в форме крыльев сокола".
- Предоставьте контекст и укажите цель. Объясните, для чего вам нужно изображение. От того, насколько хорошо модель понимает контекст, зависит конечный результат. Например, запрос "Создай логотип для бренда косметики премиум-класса в стиле минимализма" даст лучший результат, чем просто "Создай логотип".
- Повторяйте и уточняйте. Не ждите идеального изображения с первой попытки. Используйте разговорный характер модели, чтобы вносить небольшие изменения. Например, вы можете написать: "Отлично, но можешь сделать освещение немного теплее?" или "Оставь все как есть, но сделай выражение лица персонажа более серьезным".
- Используйте пошаговые инструкции. Если вы хотите создать сложную сцену с множеством элементов, разбейте запрос на шаги. "Сначала создай фон с изображением тихого туманного леса на рассвете. Затем на переднем плане добавьте покрытый мхом древний каменный алтарь. Наконец, положите на алтарь один светящийся меч".
- Используйте семантические отрицательные запросы. Вместо "без машин" опишите сцену утвердительно: "пустая, безлюдная улица без признаков дорожного движения".
- Управляйте камерой. Используйте термины из области фотографии и кино, чтобы задать композицию. Например,
wide-angle shot,macro shot,low-angle perspective.
Ограничения
- Для наилучших результатов используйте следующие языки: английский, арабский (Египет), вьетнамский, индонезийский, испанский (Мексика), итальянский, китайский (упрощенный), корейский, немецкий, португальский (Бразилия), русский, украинский, французский, хинди и японский.
- Генератор изображений не поддерживает аудиозапросы. Видео поддерживается только в Gemini Nano Banana 2.1, Gemini 3.1 Flash Image и Gemini 3.1 Flash Lite Image.
- Модель не всегда будет генерировать точное количество изображений, которое запрашивает пользователь.
gemini-2.5-flash-imageлучше всего работает, когда вы загружаете до трех изображений, аgemini-3-pro-imageподдерживает пять изображений с высокой точностью и до 14 изображений в целом.gemini-nano-banana-2.1иgemini-3.1-flash-imageподдерживают сходство до четырех персонажей и точность до 10 объектов в одном рабочем процессе.- Если вы хотите получить изображение с текстом, лучше сначала попросить Gemini сгенерировать текст, а затем – изображение с этим текстом.
- Функция Grounding with Google Search в
gemini-nano-banana-2.1иgemini-3.1-flash-imageпока не поддерживает использование реальных изображений людей из веб-поиска. - Все сгенерированные изображения содержат водяной знак SynthID.
Дополнительные настройки
Вы можете настроить формат вывода, соотношение сторон и размер изображения с помощью параметра response_format.
Формат вывода
По умолчанию модель возвращает ответы как в виде текста, так и в виде изображений. Вы можете настроить ответ так, чтобы возвращались только сгенерированные изображения (без текста разговора), указав графический формат в параметре response_format.
Чтобы запросить несколько модальностей (например, текст и сгенерированное изображение), передайте в response_format массив записей формата.
