Google 宣布了一系列重磅更新，包括最新的视频生成模型 Veo 2、图像生成模型 Imagen 3，以及一款全新的创意工具 Whisk。这些技术为视频创作、图片生成和创意表达带来了全新的可能性。
Veo 2：让视频生成更具电影感
Veo 2 是谷歌新一代视频生成模型，能够制作出高质量的视频，覆盖多种题材和风格。它不仅提升了对现实物理和人物动作的理解，还能捕捉电影级的细节和质感。例如，你可以要求它生成：低角度的动态镜头，穿梭于场景中；科学家在实验室中显微镜下专注的特写；35mm镜头拍摄的乡村蜂窝场景，阳光洒在蜂农和蜂蜜罐上等各种风格的视频。这些画面不仅清晰度高达 4K，还充满艺术性和电影感，甚至可以在几分钟时长的视频中保持一致的风格。Veo 2 还支持用户通过提示词选择各种镜头参数（如“18mm镜头”）或视觉效果（如“浅景深”），生成专业级画面。
在测试中，Veo 2 的生成质量在与其他领先的 AI 视频模型性比，它还减少了常见的 AI 生成问题，比如多余的物体或不合理的细节，让生成结果更加真实自然。
Cinematic shot of a female doctor in a dark yellow hazmat suit, illuminated by the harsh fluorescent light of a laboratory. The camera slowly zooms in on her face, panning gently to emphasize the worry and anxiety etched across her brow. She is hunched over a lab table, peering intently into a microscope, her gloved hands carefully adjusting the focus. The muted color palette of the scene, dominated by the sickly yellow of the suit and the sterile steel of the lab, underscores the gravity of the situation and the weight of the unknown she is facing. The shallow depth of field focuses on the fear in her eyes, reflecting the immense pressure and responsibility she bears.Veo 2 prompt: This medium shot, with a shallow depth of field, portrays an adorable cartoon girl with wavy brown hair and lots of character, sitting upright in a 1980s kitchen. Her hair is medium length and wavy. She has a small, slightly upturned nose, and small, rounded ears. She is very animated and excited as she talks to the camera and lighting and giggling with a huge grin.Veo 2 prompt: The camera floats gently through rows of pastel-painted wooden beehives, buzzing honeybees gliding in and out of frame. The motion settles on the refined farmer standing at the center, his pristine white beekeeping suit gleaming in the golden afternoon light. He lifts a jar of honey, tilting it slightly to catch the light. Behind him, tall sunflowers sway rhythmically in the breeze, their petals glowing in the warm sunlight. The camera tilts upward to reveal a retro farmhouse with mint-green shutters, its walls dappled with shadows from swaying trees. Shot with a 35mm lens on Kodak Portra 400 film, the golden light creates rich textures on the farmer’s gloves, marmalade jar, and weathered wood of the beehives.Veo 2 prompt: A low-angle shot captures a flock of pink flamingos gracefully wading in a lush, tranquil lagoon. The vibrant pink of their plumage contrasts beautifully with the verdant green of the surrounding vegetation and the crystal-clear turquoise water. Sunlight glints off the water's surface, creating shimmering reflections that dance on the flamingos' feathers. The birds' elegant, curved necks are submerged as they walk through the shallow water, their movements creating gentle ripples that spread across the lagoon. The composition emphasizes the serenity and natural beauty of the scene, highlighting the delicate balance of the ecosystem and the inherent grace of these magnificent birds. The soft, diffused light of early morning bathes the entire scene in a warm, ethereal glow.Veo 2 prompt: A perfect cube rotates in the center of a soft, foggy void. The surface shifts between different hyper-real textures—smooth marble, velvety suede, hammered brass, and raw concrete. Each material reveals subtle details: marble veins slowly spreading, suede fibers brushing with wind, brass tarnishing in slow motion, and concrete crumbling to reveal polished stone inside. Ends with a soft glow surrounding the cube as it transitions to a smooth mirrored surface, reflecting infinity.Veo 2 prompt: A cinematic shot captures a fluffy Cockapoo, perched atop a vibrant pink flamingo float, in a sun-drenched Los Angeles swimming pool. The crystal-clear water sparkles under the bright California sun, reflecting the playful scene. The Cockapoo's fur, a soft blend of white and apricot, is highlighted by the golden sunlight, its floppy ears gently swaying in the breeze. Its happy expression and wagging tail convey pure joy and summer bliss. The vibrant pink flamingo adds a whimsical touch, creating a picture-perfect image of carefree fun in the LA sunshine.Veo 2 prompt: The sun rises slowly behind a perfectly plated breakfast scene. Thick, golden maple syrup pours in slow motion over a stack of fluffy pancakes, each one releasing a soft, warm steam cloud. A close-up of crispy bacon sizzles, sending tiny embers of golden grease into the air. Coffee pours in smooth, swirling motion into a crystal-clear cup, filling it with deep brown layers of crema. Scene ends with a camera swoop into a fresh-cut orange, revealing its bright, juicy segments in stunning macro detail.Veo 2 亮点

Imagen 3：图像生成更精美多样
相比上一代，Imagen 3 的图像生成能力有了显著提升。无论是逼真的摄影风格，还是抽象的艺术风格，它都能以更高的细节和更丰富的质感还原用户的创意。
例如，你可以通过提示词生成：瓦片质感的陶艺场景，手工艺人用金色能量塑造陶器；雪林中一只红松鼠，毛发细节清晰可见；充满蒸汽与离别情感的1940年代欧洲火车站。Imagen 3 对用户提示的响应更准确，并在多种艺术风格之间切换自如。从印象派到动漫，从抽象艺术到写实摄影，它都能满足用户需求。
Imagen 3 prompt: An extreme close-up of a craftsperson's hands shaping a glowing piece of pottery on a wheel. Threads of golden, luminous energy connect the potter’s hands to the clay, swirling dynamically with their movements. The workspace is filled with rich textures—dusty shelves lined with tools, scattered clay fragments, and beams of natural light piercing through wooden shutters. The interplay of light and energy creates an ethereal, almost magical atmosphere
Imagen 3 prompt: A close-up shot captures a winter wonderland scene – soft snowflakes fall on a snow-covered forest floor. Behind a frosted pine branch, a red squirrel sits, its bright orange fur a splash of color against the white. It holds a small hazelnut. As it enjoys its meal, it seems oblivious to the falling snow.
Imagen 3 prompt: A foggy 1940s European train station at dawn, framed by intricate wrought-iron arches and misted glass windows. Steam rises from the tracks, blending with dense fog. Two lovers stand in an emotional embrace near the train, backlit by the warm, amber glow of dim lanterns. The departing train is partially visible, its red tail lights fading into the mist. The woman wears a faded red coat and clutches a small leather diary, while the man is dressed in a weathered soldier’s uniform. Dust motes float in the air, illuminated by the soft golden backlight. The atmosphere is melancholic and timeless, evoking the bittersweet farewell of wartime cinema.
Imagen 3 prompt: A portrait of an Asian woman with neon green lights in the background, shallow depth of field.
Imagen 3 prompt: A close-up, macro photography stock photo of a strawberry intricately sculpted into the shape of a hummingbird in mid-flight, its wings a blur as it sips nectar from a vibrant, tubular flower. The backdrop features a lush, colorful garden with a soft, bokeh effect, creating a dreamlike atmosphere. The image is exceptionally detailed and captured with a shallow depth of field, ensuring a razor-sharp focus on the strawberry-hummingbird and gentle fading of the background. The high resolution, professional photographers style, and soft lighting illuminate the scene in a very detailed manner, professional color grading amplifies the vibrant colors and creates an image with exceptional clarity. The depth of field makes the hummingbird and flower stand out starkly against the bokeh background.Imagen 3 亮点
- 更亮眼的图像效果，色彩更鲜艳，构图更优秀，细节更丰富。
- 支持多种艺术风格，从写实到幻想，转换流畅。
